ea 9777-3 page 3 electronic assembly reserves the right to change specifications without prior notice. printing and typographical errors reserved. quick start 1.) installation the evaluation board is conntected to a free usb-port of the pc with the delivered usb-cable. windows detects the new hardware. drivers for all supported different windowsversions are found on the cd in the folder: d:\drivers: after successfully installing the driver, both green leds (left and right) will shine. the eval-boards of the both tft-displays (ea evalediptft57 & ea evalediptft70) do need an external power supply. the supplied ac-adaptor has to be plugged in. once the eval- board is powered the green led at the bottom right is lit. the next step is installing the ea kit-editor and compiler of edip-series. the setupfile ?setup lcd-tools portable? is found in the root-directory of the cd. please follow the instructions of the installer. 2.) first-time operation of display mount your edip on the evaluation board. make sure that it is mounted correctly, pin 1 is placed in the lower left corner. 3.) compile and flash the display run ea kit-editor and choose a project. to open a project, please go to the context menu: ?file- >open? and select a file (*.kmc). during installation of kit-editor some examples are installed, please find them under: :\lcd tools\data\edip - intelligent graphic displays\edip???\how to use\. please make sure to use the right folder, suitable for your module. please choose a subject you are interested in and open one of the project files. to compile the project and download it onto the module only one additional click is needed. the farest right icon ?compile? starts compilation and downloads the successfully compiled project automatically to the display.
ea 9777-3 page 4 electronic assembly reserves the right to change specifications without prior notice. printing and typographical errors reserved. 4.) useful tool ?ea lcd terminal? after starting the terminal (from ea kit-editor: the second icon from the right) a dialog is shown with all present serial interfaces. please choose the one labeled with ?x: edip programmer (comx)?. the evaluation board has the baudrate 115200. please activate the small-protocol (shift+f8) to exchange data and commands with the display. 5.) useful tool ?ea bitmapedit? the ea bitmapedit is a simple image processing program. it?s designed to use with the edip-series, it can save and load all formats (e.g. *.g16, *.bh7) of ea edip- series. in addition, you can create elementary animations, by dragging the single pictures onto the editor. 6.) useful tool ?ea instrument editor? the ea ediptft-series is able to show analogue pointer instruments. to create those instruments you have to use this editor.
ea 9777-3 page 5 electronic assembly reserves the right to change specifications without prior notice. printing and typographical errors reserved. ea 9777-3usb evaluationboard the evaluation board provides a variety of features, starting with leds to indicate data-transfer, ending with potentiometers to use the analogue inputs of ea ediptfts. the lands j8 are directly connected with the corresponding pin of the edip. if you remove the 0r- resistors the periphery is completly disconnected. please refer to the schematic on the last page. note: not all functions of the evaluation board are supported by every display of the edip-series. function of potentiometer both potentiometers are connected to the anolgue inputs of the ediptfts. they set the voltage of ain1 and ain2 between gnd and vdd.
ea 9777-3 page 6 electronic assembly reserves the right to change specifications without prior notice. printing and typographical errors reserved. function of jumpers - ?disable power on macro?: if a continuous loop is programmed either in poweron-, reset-, watchdog- or brownout-macro, the display is no longer adressable. in this case you have to restrain the run of power-on-macro. this is done by the jumper: switch power off, set the jumper to the right (dpom to gnd). now you have to re- power the module and release the jumper or set it to the left (dpom is open). - ?disable protocol?: the small-protocol can be disabled. this might be helpful espacially in the early stage of development. it is strongly recommended to activate the protocol in series, to monitor data- transfer. if the jumper is set to the left, the protocol is deactivated (dprot to gnd). if the jumper is set to the right or left open, the protocol is activated (dprot open). you have to reset the module if you want to change the protocol-mode. - ?testmode?: each edip includes a testmode, which can be activated with the help of a jumper: set the jumper to the left (test to gnd) and a test screen will be displayed. if you want to change to normal operation you have to release the jumper or set it to the right (test open) and reset the module. function of leds - ?usb-power? (green): this led indicates a connected usb-cable. - ?vdd power? (green): this led indicates the evaluation board to be power-supplied - ?usb-txd? (red): this led indicates data is transferd to the edip. - ?usb-rxd? (green): this led indicates data is send by the edip. - ?sbuf? (orange): this led glows if data is present in the sendbuffer of the display (sbuf low). - ?output 1-8? (green): these leds are directly connected to the outputs of the ediptft. they are lit if the output of ediptft is set to high. the ea edip320-8 has no outputs, so this function is not available. testmode on protocol off dpom active
ea 9777-3 page 7 electronic assembly reserves the right to change specifications without prior notice. printing and typographical errors reserved. usb-interface the evaluation board is connected to a free usb-port of your pc using the supplied usb-cable. the usb-interface is located at the upper left corner of the evalation board. if you connect the usb-cable, the led ?usb-power? (green) is on. if the driver for windows is installed correctly the led ?usb driver? is also lit. the scope of delivery includes a cd on which you can find the drivers for the board under ?d:\driver\. these drivers are designed for windows 2000, xp, vista, 7. to install the drivers please follow the instructions of your operating system. function of pushbuttons - ?resetbutton?: as long as you push this button the ea edip is in reset mode (reset to gnd). after release of button poweronmacro is run. - ?input 1-8?: these 8 buttons are directly connected to the inputs of the ea ediptfts. if you push a button the corresponding input is grounded. please refer to the schematic on the last page of this datasheet. (external) powersupply the eval-board has a 2.1 mm power socket for external supply. the supply range is between 12v to 28vac. external supply is optional if you are using the starterkit ea evlaedip320, i.e. normally power over usb is used. both of the starterkits of ea ediptft-series need external supply, an ac-adapter is included with your delivery. the supply source is selcted by a solder bridge, which is preset correctly.
ea 9777-3 page 8 electronic assembly reserves the right to change specifications without prior notice. printing and typographical errors reserved. port expansion ea 9777-2pe (included in ea evalxxx) the optional adapter board ea 9777-2pe expands the evaluation board with important interfaces: ?real? rs232, rs232 cmos, rs485, spi and i2c. the board consists of 5 individual adapter boards, which have to be carefully broken asunder the perforation. each adapter board has two leds two indicate data transfer. in addition there is a dip-switch. the adapters intermit the usb connection between evaluation board and pc and configures the edip for the desired interface. please make sure to reset the display every time you change the interfaces. to reuse the usb connection again, you have to removethe adapter board and reset the display. pin connectors of the board in connection with interface expantion the pin coennectors, you can see on the board ea 9777-3usb provide the repective interfaces. attention: the following description of pin connectors are only operable if the optional available adapter board ea9777-2pe is mounted.
