oled-displays page 3 specifications may be changed without prior notice. printing error reserverd pinout self definied character all these character display modules got the feature to create 8 own characters (ascii codes 0..7) in addition to the rom fixed codes. 1.) the command ?cg ram address set? defines the ascii code (bit 3,4,5) and the dot line (bit 0,1,2) of the new character. example demonstrates creating ascii code $00. 2.) doing 8 times the write command ?data write? defines line by line the new character. 8th. byte stands for the cursor line. 3.) the new defined character can be used as a ?normal? ascii code (0..7); use with ?dd ram address set? and ?data write?. adresse im cg ram setzen daten des zeichens adresse hex bit hex 7 6 5 4 3 2 1 0 01 000 000 $40 xxx 0010 0 $04 001 $41 0010 0 $04 010 $42 0 0 1 0 0 $04 011 $43 0 0 1 0 0 $04 100 $44 1010 1 $15 101 $45 0111 0 $0e 110 $46 0 0 1 0 0 $04 111 $47 0 0 0 0 0 $00 it must be noted that the character font setting must be performed at the head of the program before executing any instructions other than the busy flag and address instruction. otherwise, the function set instruction cannot be executed unless the interface data length is changed. it is possible to choose one of the shown char sets. the english/japanese char set is setted by default . you have to set the bits ft1/ft0 of function set register: ft 1 ft 0 description 0 0 englisch japanese character font table 0 1 western european character font table 1 1 0 english russian character font table 1 1 western european character font table 2 pin symbol level descript ion 8 bit-mode 4 bit-mode 1 gnd l(0v) ground ground 2 vcc h(5v) supply voltage supply voltage 3 n.c. --- not connected not connected 4 rs h/l h: data, l: instruction code h: data, l: instruction code 5 r/w h/l h: read, l: write h: read, l: write 6 e h, h- >l enable enable 7 db0 h/l data bit 0 (lsb) do not connect 8 db1 h/l data bit 1 do not connect 9 db2 h/l data bit 2 do not connect 10 db3 h/l data bit 3 do not connect 11 db4 h/l data bit 4 data bit 0 (lsb) 12 db5 h/l data bit 5 data bit 1 13 db6 h/l data bit 6 data bit 2 14 db7 h/l data bit 7 (msb) data bit 3 (msb) 15 n.c. --- not connected not connected 16 n.c. --- not connected not connected
