Looks very nice! Compliments! Where did you find the datasheet of the display? Carsten > I connected a Nokia 3310 LCD display to the C-Control. I had to convert 5 to 3 V using a LM317 and a 74HC245. The display is quite dumb in terms of characters etc. It is just a graphical display and character sets must be loaded in the microcontroller itself. The display is controlled using SPI protocol. Quite simple: data is clocked in to the data input each high->low cycle of the clock. As a demonstration I donwloaded a bitmap on the display as can be seen on picture. > > For your interest, the source code: > '-------------------------- > '------ I/O PORTS --------- > '-------------------------- > ' 1 vdd > ' 2 sclk > ' 3 sdin > ' 4 d/c > ' 5 sce > ' 6 gnd > ' 7 vout > ' 8 res > define nok_sclk port[13] > define nok_sda port[12] > define nok_dc port[11] > define nok_cs port[10] > define nok_res port[9] > define i as byte > define row as byte > define column as byte > define iloop as byte > define oloop as byte > define tmp as byte > define tmp2 as byte > define x as word > define val as byte > > goto main > > '------ SHOW A HEX NIBBLE ------------------------- > FUNCTION HEXNIBBLE(TEMP as byte) > if TEMP<10 then > put (TEMP+48) > ELSE > put (TEMP+55) > END IF > END FUNCTION > '------------------------------------------------- > '-- SHOW CONTENT OF VAL AS HEX VALUE - > '------------------------------------------------- > FUNCTION SHOW_HEX(VAL as byte) > define TEMP as byte > TEMP=VAL/16 > HEXNIBBLE(TEMP) > TEMP=VAL MOD 16 > HEXNIBBLE(TEMP) > END FUNCTION > > > > FUNCTION DELAY (DEL as byte) > for oloop=0 to DEL '10ms steps > for iloop=1 to 200 > NEXT > NEXT > END FUNCTION > > > function NLCD_Write (data as byte, mode as bit) > put data > ' Pull nok_dc true or false depending on mode > if (mode) then > nok_dc = true > else > nok_dc = false > end if > nok_cs = false > ' Clock in 8 bits of data > for i = 1 to 8 > nok_sclk = false > if (data and 80h) = 0 then > nok_sda = false > else > nok_sda = true > end if > nok_sclk = true > data = data shl 1 > next i > > nok_cs = true > End Function > > function NLCD_GotoXY (xnokia as byte, ynokia as byte) > NLCD_Write( 40h or ( ynokia and 7h ), false) > NLCD_Write( 80h or ( xnokia and 7fh ), false) > end function > > function NLCD_Clear() > ' Data bit is false > nok_sda = false > ' Data mode > nok_dc = true > nok_cs = false > > for row= 1 to 6 > ' 6 rows > for column = 1 to 84 > ' 84 columns or "pages" > for i=1 to 8 > ' Clock for the 8 bits of the "page" > nok_sclk = false > nok_sclk = true > next i > next column > next row > end function > > function NLCD_Init() > ' Set initial status of LCD pins > nok_sclk = false > nok_sda = false > nok_dc = false > nok_cs = false > nok_res = false > > ' Toggle LCD Reset > DELAY(1) > nok_res = false > DELAY(25) > nok_res = true > > nok_cs = true > ';; Extended commands > NLCD_Write (21h, false) > ';; LCD Vop > NLCD_Write (c5h, false) > ';; Temp coef > NLCD_Write (6h, false) > ';; LCD Bias 1:48 > NLCD_Write (13h, false) > ';; Standard commands > NLCD_Write (20h, false) > ';; Normal Mode > NLCD_Write (0ch, false) > > ' Clear and position at top of LCD > NLCD_Clear(); > NLCD_GotoXY(0,0); > > end function > > #main > NLCD_Init() > ' NLCD_GotoXY (0,0) > FOR x = 1 TO 504 > val = Looktab(bmp_table,x) > > NLCD_Write(val,true) > next x > end > > Table bmp_table > 00 00 00 00 00h F8h F8h 60h 80h F8h F8h 00h > C0h E0h 20h 20h E0h C0h 00h F8h > F8h 80h C0h 60h 20h 00h E8h E8h > 00h 40h A0h A0h E0h C0h 00h 00h > 00h 00h 10h 18h 48h F8h B0h 00h > 10h 18h 48h F8h B0h 00h 60h 30h > F8h F8h 00h 00h F0h F8h 08h F8h > F0h 00h 00h 00h 00h F8h F8h 00h > 00h 00h 00h 00h E0h F0h 18h 08h > 08h 18h 10h 00h F8h F8h 08h 08h > F8h F0h 00h 00h > 00h 07h 07h 00h 01h 07h 07h 00h > 03h 07h 04h 04h 07h 03h 00h 07h > 07h 01h 03h 87h 84h 80h 07h 07h > 00h 03h 07h 04h 07h 07h 80h 80h > 80h 00h 02h 06h 04h 07h 03h 00h > 02h 06h 04h 07h 03h 00h 00h 80h > 07h 07h 00h 00h 03h 07h 04h 07h > 03h 00h 00h 00h 80h 07h 07h 04h > 04h 84h 04h 00h 01h 03h 06h 84h > 04h 06h 82h 80h 87h 07h 04h 04h > 07h 03h 00h 00h > 00h 00h 3Ch 42h 42h 42h 3Ch 00h > 7Eh 02h 02h 02h 7Ch 00h 00h 00h > 00h 1Eh 21h 40h 40h 40h 21h 00h > 10h 10h 10h 00h 1Eh 21h 40h 40h > 40h 21h 00h 3Ch 42h 42h 42h 3Ch > 00h 7Eh 02h 02h 02h 7Ch 02h 7Fh > 42h 00h 7Eh 04h 02h 00h 3Ch 42h > 42h 42h 3Ch 00h 7Fh 00h 00h 00h > 00h 7Fh 03h 1Ch 60h 1Ch 03h 7Fh > 00h 41h 60h 50h 48h 47h 00h 00h > 00h 00h 00h 00h > 01h 01h FFh 00h C0h 70h 18h 08h > 08h 18h 30h E0h 80h 00h 00h 00h > 00h 00h 00h 00h 00h 00h 00h 00h > 00h 00h 00h 00h 80h 80h 80h 80h > 00h 00h 00h 00h 00h 00h 00h 00h > 00h 00h 00h 00h 00h 00h 00h 00h > 00h 00h 00h 00h 00h 00h 00h 00h > 00h 00h 00h 00h 00h 00h 00h 00h > 00h 00h 00h 00h 00h 00h 00h 00h > 00h 00h 00h 00h 00h 00h 00h 00h > 00h 00h 00h 00h > 01h 01h FFh 1Eh 03h 00h 00h 00h > 00h 00h 00h 00h 07h 1Ch F0h 80h > 00h 00h 00h 00h 00h 00h 00h 80h > E0h 38h 0Eh 03h 01h 00h 00h 00h > 00h 01h 01h 06h 18h 70h C0h 80h > 00h 00h 80h F0h 10h 18h 08h 08h > 18h 10h 60h 40h 00h 00h 00h 00h > 80h 40h 40h 40h 40h 80h 00h 00h > 80h 40h 40h 40h 80h 00h 00h 00h > 00h 00h 00h C0h 00h C0h 40h 40h > 40h 40h 80h 00h > 81h 81h FFh 80h 80h 80h 80h 80h > 80h 80h E0h 80h 80h 80h 80h 83h > 82h 82h E6h 84h 86h 82h 81h 81h > 80h 80h E0h 80h 80h 80h 80h 80h > 80h 80h E0h 80h 80h 80h 80h 81h > 81h 81h E0h 80h 80h 80h 80h 80h > 80h 80h E0h 80h 80h 80h 00h 00h > 11h 22h 22h 24h 24h 18h 00h 0Fh > End Table > |
