2 ea kit320-8 *) also available at http://www.lcd-module.de/deu/disk/disk320.zip general the ea kit320 is a fully assembled control and operating unit with a variety of integrated functions. the display has very compact dimensions and offers excellent super-twist contrast, which means the unit can be put into operation immediately. it is controlled via the standard rs-232 or rs-422 interface. in addition to complete graphics routines for display output, the operating unit also contains a wide variety of fonts. graphics commands similar to high-level language are used for programming. there is no longer any need for the time-consuming programming of character sets and graphics routines. the ease of use offered by macros and input via touch panel make it a real power display. hardware the operating unit is designed to work with an operating voltage of +5v. a supply voltage of 9..35v is also possible. serial asynchronous data transfer is carried out in rs-232 or rs-422 format. the transmission format is set permanently to 8 data bits, 1 stop bit, and no parity. rates between 2,400 baud and 115,200 baud can be selected by means of dip switches. rts and cts handshake lines are available. data format: touch panel the ea kit320-8ctp and -8lwtp versions are equipped with an integrated touch panel. you can make entries and menu or bar graph settings by touching the display. the labeling of the ?keys? is flexible and can also be changed during runtime (different languages, icons). the drawing of the individual ?keys? and the labeling is handled by the integrated software. software the operating unit is programmed by means of commands, such as draw a rectangle from (0,0) to (64,15) . no additional software or drivers are required. strings can be placed with pixel accuracy. flashing attributes can be assigned as often as you like ? for graphics as well. text and graphics can be combined at any time. up to 16 different character sets can be used. each one can be zoomed from 2 to 8 times. with the largest character set, the words and numbers displayed will fill the screen. accessories floppy disk for macro creation a floppy disk (ea disk320) is required for macro programming *) . this converts the commands entered in a text file into a code that can be read by the operating unit, and programs them into the flash prom. cable for pc to enable simple connection to pcs (specifically for macro programming), we provide an optional 1.5m cable and a 9-pin sub-d female connector (ea kv24-9b). simply insert it into com 1 or com 2 and get started. note: the cable is not suitable for the rs-422 version ea opt-rs4224. 3 ea kit320-8 rs-422 connector j3 pin symbol function 1 vdd + 5v supply 2 data in- receive data 3 data in+ receive data 4 data out- transmit data 5 data out+ transmit data 6 hs in- handshake 7 hs in+ handshake 8 hs out- handshake 9 hs out+ handshake 10 gnd 0v ground rs-232 connector j3 pin symbo in/out function 1 vdd - + 5v supply 2 dcd - connected to dtr 3 dsr - connected to dtr 4 txd out transmit data 5 cts in clear to send 6 rxd in receive data 7 rts out request to send 8 dtr - see pin 2, pin 3 9 - - nc 10 gnd - 0v ground baudrates dip switch data format 8,n,1 1 2 3 on on 2,400 off on on 4,800 off on 9,600 off off on on 19,200 off on 38,400 off off on 57,600 off off 115,200 off off off extension j5 pin symbol in/out function 1 vu - 9..35v supply 2 vdd - + 5v supply 3 gnd - 0v, ground 4 txd5 out transmit data 5 rxd5 in receive data 6 rts5 out request to send 7 cts5 in clear to send 8 reset in l: reset 9 scl out i2c b us, c lock 10 sda in/out i2c b us, d ata view from rear side supply voltage in the standard model, the supply voltage of +5v is fed in via the screw-type terminal j1. in the case of the version for 9v to 35v (ea opt-9/35v), the power is supplied via j2. important: it is imperative that the polarity is correct. even very brief polarity reversal can damage the entire operating unit immediately and irreparably. baud rates the baud rate can be set by means of the three dip switches on the left. when the equipment is delivered, the setting is 9,600 baud (dip 3 on). please note that the internal data buffer is only 128 bytes. the rts handshake line must therefore be queried (+10v level: data can be accepted; -10v level: display is busy). the data format is set permanently to 8 data bits, 1 stop bit, no parity. rs-232/rs-422 the operating unit is shipped with an rs- 232 interface as standard. the pin assignment of connector j3 is then as shown in the table on the left. j3 has a grid of 2.54mm. if the operating unit is ordered together with the ea opt-rs4224 option, special rs-422 drivers are fitted. the pin assignment in the table on the right then applies. incidentally, the same serial data with 5v levels and ttl logic is available at the j5 eyelet strip. these levels are suitable for direct connection to a c. if these signals are used, 4 solder straps lb1, lb2, lb 5 und lb 6 has to be opened ! 4 ea kit320-8 inputs and outputs all ea kit320 operating units are supplied with 8 digital inputs and 8 outputs (5v cmos level, non-isolated). 8 outputs each line can be controlled by means of the ?esc y w? command. the maximum current per line is 6ma. it is therefore possible to connect an led (low current) directly to an output. higher currents can be amplified by means of external transistors. 8 inputs the inputs can be queried and evaluated (?esc y r?) directly via the serial interface. it is also possible to call a bit/port macro automatically in the event of changes at the inputs. automatic port querying can be deactivated by means of the ?esc y a 0? command. port macros: up to 256 port macros can be addressed by means of the binary combination of 8 inputs. bit macros each only affect one input. bit macro 1..8 is called at one of inputs 1...8 in the event of a change to high level. bit macros 9..16 are called in the event of a change to low level. at each change of the input port, the bit macros are executed first, followed by the port macro. if there is no macro defined, the new port status is sent via rs232/rs422. each of the macros can change the contents of the screen or switch outputs. this allows a wide range of control tasks to be carried out. to create the macros, you need a pc and the floppy disk ea disk320. note: the logic circuitry is designed for slow operations; in other words, more than 3 changes per second cannot be easily executed. if an input is open, this is evaluated as high (internal 100 kohm pullup). inputs and outputs via opt ocouplers (ea opt -opto16) the inputs and outputs can be equipped optionally with optocouplers (ea opt-opto16). the inputs and outputs are then isolated from the rest of the electronic components as well as each other. the connection is made via 16 different screw-type terminals. voltages of 5..35v can be applied directly at all 8 inputs. voltages of over 4v are identified as high (h) level; voltages of under 2v are identified as low (l) level. voltages between 2 and 4v are undefined. the collector and emitter of a transistor are each implemented as outputs on the screw-on terminals. each output can switch a maximum of 10ma. note: the negative pole of each screw-on terminal can be interconnected by closing solder straps lbi1..8 or lbo1..8. in addition, these solder straps can be connected to system gnd (solder 0 ? bridge rgnd). note: the optocouplers invert the input logic (all inputs open: port macro n255). it is advisable here (in the power-on macro, for example) to use the ?esc y i 1? command to evaluate the inputs inversely (i.e. all inputs open: port macro n0). in- and output j120 pin symbol function pin symbol function 1 vdd +5v supply 2 gnd 0v, ground 3 out1 / mo8 port output 1 matrix output 8 4 in1 / mi8 port input 1 matrix input 8 5 out2 / mo7 port output 2 matrix output 7 6 in2 / mi7 port input 2 matrix input 7 7 out3 / mo6 port output 3 matrix output 6 8 in3 / mi6 port input 3 matrix input 6 9 out4 / mo5 port output 4 matrix output 5 10 in4 / mi5 port input 4 matrix input 5 11 out5 / mo4 port output 5 matrix output 4 12 in5 / mi4 port input 5 matrix input 4 13 out6 / mo3 port output 6 matrix output 3 14 in6 / mi3 port input 6 matrix input 3 15 out7 / mo2 port output 7 matrix output 2 16 in7 / mi2 port input 7 matrix input 2 17 out8 / mo1 port output 8 matrix output 1 18 in8 / mi1 port input 8 matrix input 1 19 gnd 0v, ground 20 vdd +5v supply 5 ea kit320-8 type 1: 2x2 matrix type 2: 1x4 matrix type 3: 4x0 matrix external matrix keyboard a matrix keyboard (anything from individual keys to an 8x8 matrix keyboard) can be connected at the plug-in connection j120. the number of inputs and outputs of the ports (n1,n2=1..8) used is defined and the key debouncing is specified (n3=0..7 in 50ms increments) by means of the ?esc y m n1 n2 n3? command. please note when an external keyboard is connected that the digital inputs are reduced by the number n1 and the outputs are reduced by the number n2. each key is generally switched between an output and an input. each input has a 100k ? (approx.) pullup. in order to identify double keystrokes, the outputs must be decoupled from each other. this is best done with schottky diodes (e.g. bat 43). transmitting the keystrokes at each keystroke (key number 1..64), the associated matrix macro is executed or, if no macro is defined, the key number is transmitted with code letters. the release of the key is not transmitted. if the release of the key is to be transmitted as well, this can be done by defining matrix macro no. 0. note if the cts handshake line does not permit transmission, up to 8 keystrokes are stored in the key buffer. when the buffer is full, older keystrokes may be lost. determining the key number: key no. = (output no. - 1) * no. of inputs + no. of outputs (output = mox, input = mix). example: connection of 4 keys in 3 variations - variant 1: the 4 keys are defined as a 2x2 matrix by means of the ?esc y m 2 2 ..? command. the keys are connected to 2 inputs (mi1, mi2) and 2 outputs (mo1, mo2). the outputs are decoupled from each other by means of diodes so that double keystrokes can be identified. there are 6 inputs and 6 outputs available as port connections. - variant 2: the 4 keys are defined as a 1x4 matrix by means of the ?esc y m 1 4 ..? command. the keys are connected to 4 outputs (mo1, mo2) and read in via input mi1. there are 7 inputs and 4 outputs available as port connections. - variant 3: if only one output is used (4x1 matrix), the keys can also be connected to ground and read in directly at the inputs (= 4x0 matrix). the 4 keys are defined at the 4 inputs (mi1..mi4) by means of the ?esc y m 4 0 ..? command. there are 4 inputs and 8 outputs available as port connections. 6 ea kit320-8 connection for dot-matrix display you can connect a single external dot-matrix module (with hd44780 or compatible) with 1x8 up to 4x20 or 2x40 characters at eyelets j6 and j7. this dot-matrix display can be addressed very conveniently by means of ?esc t xx? terminal commands. alternatively, ?esc l xx? commands are available for controlling the hd44780 directly. a potentiometer for contrast adjustment is already fitted. a suitable series resistor r led can be fitted for led backlighting. macro programming single or multiple command sequences can be grouped together in macros and stored in the data flash. you can then start them by using the run macro commands. there are different types of macro: normal macros (0..255) these are started by means of an ?esc mn xx? command via the serial interface or from another macro. a series of macros occurring one after the other can be called cyclically (movie, hourglass, multi-page help text). these automatic macros continue to be processed until a command is received via rs-232 or another macro is activated (e.g. touch, port or matrix macro). touch macro (1..255) started when you touch/release a touch field (only in versions with a touch panel - tp) or issue an ?esc mt xx? command. menu macro (1..255) started when you choose a menu item or issue an ?esc mm xx? command. bit macro (1..8) or (9..16) started when a voltage is applied/changed at individual inputs in 1..8 (bitwise) or by means of an ?esc mb xx? command. bit macros 1..8 respond to a rising edge, whereas bit macros 9..16 respond to a falling edge of inputs 1..8. port macro (0..255) started when a voltage is applied/changed at the 8 inputs in 1..8 (binary combined) or by means of an ?esc mp xx? command. matrix macro (0..64) matrix macro 1..64: started when you press a key or issue an ?esc mx xx? command. matrix macro 0: started on release when a key is no longer depressed or by means of a command. the matrix keyboard is connected at the inputs and outputs; a single 8x8 matrix keyboard can be connected at most. power-on macro started after power-on. you can switch off the cursor and define an opening screen, for example. reset macro started after an external reset or after a voltage drop under 4.7v (vdd-vss). watchdog macro started after a fault/error (e.g. failure). important: if a continuous loop is programmed in the power-on, reset or watchdog macro, the display can no longer be addressed. in this case, the only thing you can do is: dip switch 5 to on, power-off, power-on and then dip 5 to off. the macros then have to be read in again. dotmatrix connector j6 + j7 pin symbol pegel description 1 vss l 0v, ground 2 vdd h +5v supply 3 vee - display voltage 0v-5v 4 rs h/l register select 5 r/w h/l h:read/l:write 6 e h enable 7 d0 h/l data0(lsb) 8 d1 h/l data 1 9 d2 h/l data 2 10 d3 h/l data 3 11 d4 h/l data 4 12 d5 h/l data 5 13 d6 h/l data 6 14 d7 h/l data7(msb) 15 a - anode (rled) 16 k l kathode (=vss) 7 ea kit320-8 256 images stored in the internal data flash to reduce the transmission times of the serial interface or to save storage space in the processor system, up to 256 images can be stored in the internal data flash. they can be called using the ?esc u i? command or from within a macro. all images in the windows bmp format (monochrome images only) can be used. they can be created and edited using widely available software such as windows paint or photoshop (only black and white = 1 bit). creating individual macros to create your own macros, you need the following: - the ea disk320 *) floppy disk, which contains a compiler, examples and fonts - a pc with a com1 or com2 serial interface and approximately 500kb of hard disk space - a text editor such as wordpad or textpad to define a sequence of commands as a macro, all the commands are written to a file on the pc (e.g. demo.kmc). you specify which character sets are to be integrated and which command sequences are to be in which macros. once the macros are defined, you start the program c:>kitcomp demo.kmc. this creates a data flash file called demo.df, which is then automatically stored in the data flash with the baud rate entered. this only takes a few seconds, and you can then use your user-defined macros immediately. you will find a detailed description of how to program macros, together with examples, in the files doku.doc (for word) and doku.txt (dos) on the ea disk320 *) floppy disk. write protection for macro programming pcb rev.c and newer: by setting dip switch 6 (write enable) to off, you can prevent the programmed macros, images and fonts from being overwritten inadvertently. after successful programming, this dip switch 6 should be set to off. (caution: on older pcb boards rev.a and rev.b (before 2002) dip switch 6 had reverse meaning: on=write protect; off=programming possible) *) also available at http://www.lcd-module.de/deu/disk/disk320.zip 8 ea kit320-8 internal font 5: 7x12 monospaced internal font 6: 8x16 monospaced internal font 1: 4x6 monospaced internal font 2: 5x6 monospaced internal font 3: 6x8 monospaced internal font 4: 8x8 monospaced 9 ea kit320-8 tip: font effects with large fonts, you can use the command 'esc zm' mode (link, pattern) to produce interesting effects through overlaying (writing and offsetting a word several times). original font 8x16 with zoom 3 at position 0,0 without pattern "outline font" produced by overlaying (exor) at pos. 1,1 overlaying (exor) of the "outline font" at pos. 2,2 . results in an "outline font with fill" overlaying ( or ) with 50% gray pattern of the "outline font" at pos. 0,0 . results in a "font with pattern fill" e.g. external font 10: geneva15.fxt proportional e.g. external font 7: chicago.fxt proportional font examples this hardcopy shows 6 internal and 8 external fonts. integrated and external fonts there are 6 monospaced character sets integrated as standard that can be used in terminal and graphics mode. each character set can be increased in height from 1 to 8 times in graphics output. independently of this, the width can also be increased two to eight times. each character can be positioned with pixel accuracy . text and graphics can be combined as required. several different font sizes can also be displayed together. each text can be output left justified, right justified or centered. rotation in 90 steps is also possible (for vertical installation of the display, for example). macro programming permits a further 10 fonts to be integrated. proportional character sets are also possible (in graphics mode only); these look better and take up less space on the screen. all conceivable fonts up to 255x240 pixels in size can be created using a text editor and programmed in using the kit compiler. 10 ea kit320-8 all functions at a glance ea kit320: command table 1 after reset command codes remarks comands for outputting strings output string l: left justified, c: centered r: right justified esc z l xx1 yy1 text ... nul a string (...) is output to xx1,yy1. nul ( $00), 'lf' ($0a) or 'cr' ($0d) = end of string; several lines are separated by the character '|' ($7c); text between two '~' ($7e) characters flashes on/off; text between two '@' ($40) characters flashes inversely; c r set font f n1 set font with the number n1 (1..16) 5 font zoom factor z n1 n2 n1 = x zoom factor (1x..8x); n2 = y zoom factor (1x..8x) 1,1 add. line spacing y n1 insert n1 pixels between two lines of text as additional line spacing text angle w n1 text output angle: n1=0: 0; n1=1: 90; n1=2: 180; n1=3: 270; 0 text mode v n1 mode n1: 1=set; 2=delete; 3=inverse; 4=replace; 5=inverse replace; 4 text pattern m n1 link text with pattern no. n1; 0 = do not link text with pattern 0 string for terminal esc z t text ... command for outputting a string in a macro to the terminal draw straight lines and points draw rectangle esc g r xx1 yy1 xx2 yy2 draw four straight lines as a rectangle from xx1,yy1 to xx2,yy2 draw straight line d xx1 yy1 xx2 yy2 draw straight line from xx1,yy1 to xx2,yy2 continue straight line w xx1 yy1 draw a straight line from last end point to xx1, yy1 0 draw point p xx1 yy1 set one point at coordinates xx1, yy1 point size/line thickness z n1 n2 n1 = x point size (1..15); n2 = y point size (1..15); 1,1 graphic mode v n1 set drawing mode n1: 1=set; 2=delete; 3=inverse; 1 pattern m n1 set straight line/point pattern no. n1; 0 = do not use pattern 0 change/draw rectangular areas delete area esc r l xx1 yy1 xx2 yy2 delete an area from xx1,yy1 to xx2,yy2 (all pixels out) invert area i xx1 yy1 xx2 yy2 invert an area from xx1,yy1 to xx2,yy2 (invert all pixels) fill area s xx1 yy1 xx2 yy2 fill an area from xx1,yy1 to xx2,yy2 (all pixels on) area with fill pattern m xx1 yy1 xx2 yy2 n1 draw an area from xx1,yy1 to xx2,yy2 with pattern n1 (always set) draw box o xx1 yy1 xx2 yy2 n1 draw a rectangle xx1,yy1 to xx2,yy2 with fill pattern n1 (always replace) draw frame r xx1 yy1 xx2 yy2 n1 drawaframeofthetypen1fromxx1,yy1toxx2,yy2(alwaysset) draw frame box t xx1 yy1 xx2 yy2 n1 draw a frame box of the type n1 from xx1,yy1 to xx2,yy2 (always replace) bitmap image commands image from clipboard esc u c xx1 yy1 the current contents of the clipboard are loaded to xx1,yy1 with all the image attributes load internal image i xx1 yy1 nr load internal image with the no.

(hex: $23, dec: 35). - the command letters come directly after the ?#? character. - the parameters are transmitted as plain text (several ascii characters) followed by a separating character (such as a comma ?,?). - strings (text) are written directly without quotation marks and concluded with cr (hex: $0d) or lf (hex: $0a). 2. binary mode - the escape character corresponds to the character esc (hex: $1b, dec: 27). - the command letters are transmitted directly. - the coordinates xx and yy are transmitted as 16-bit binary values (fiirst the low byte and then the high byte). - all the other parameters are transmitted as 8-bit binary values (1 byte). - strings (text) are concluded with cr (hex: $0d) or lf (hex: $0a) or nul (hex: $00). no separating characters, such as spaces or commas, may be used in binary mode. the commands require no final byte , such as a carriage return (apart from the string $00). 15 ea kit320-8 example codes can be output in ascii mode for terminal.exe #zl117, 32,test zeppelinstrasse 19 d- 82 205 gilching phone +49-8105-778090 fax +49-8105-778099 http://www.lcd-module.de ea kit320-8 dimensions w/o touch panel dimensions with touch panel all dimensions are in mm all dimensions are in mm frontpanel ea 0fp320-8 panel cut out all dimensions are in mm mouser electronics authorized distributor click to view pricing, inventory, delivery & lifecycle information: electronic assembly: ? ea kit320-8ctp |
