Ojla,

Je že komu uspelo priklopit grafični LCD 240 x 128 pixlov na avrja in ga sprogramirat z Bascom om? Bascom namreč podpira tudi takšne displaye. Uporabljam atmega163 in 240 x 128 lcd z t6963c čipom. Meni namreč ne uspe, ali se ne prižge (kot bi bil v resetu) ali pa prižiga pixle po svoje...

Kakšne so vaše izkušnje?

Pozdrav
Tomzi.

Jp. Jaz delam z njim. Ampak bos moral vec napisat, da ti bom/o lahko pomagali... Meni vcasih stegne, ker imam preslab napajalnik...Pa sem resil zadevo za silo tako, da sem dal v blizino lcdja en velik kondenzator... in dela ok.

Saj sem napisal...
Povezave sem preveril, in so ok... zalaufat pa ga noče... Tebi je delalo iz prve?

Config Graphlcd = 240 * 128 , Dataport = Porta , Controlport = Portc , Ce = 3 , Cd = 0 , Wr = 2 , Rd = 1 , Reset = 4 , Fs = 5 , Mode = 8
'The dataport is the portname that is connected to the data lines of the LCD
'The controlport is the portname which pins are used to control the lcd
'CE, CD etc. are the pin number of the CONTROLPORT.
' For example CE =2 because it is connected to PORTC.2


'Dim variables (y not used)
Dim X As Byte , Y As Byte
Wait 3
Do
'Clear the screen will both clear text and graph display
Cls

'Other options are :
' CLS TEXT to clear only the text display
' CLS GRAPH to clear only the graphical part

'locate works like the normal LCD locate statement
' LOCATE LINE,COLUMN LINE can be 1-8 and column 0-30
Locate 1 , 1

'Show some text
Lcd "MCS Electronics"
'And some othe text on line 2
Locate 2 , 1 : Lcd "T6963c support"

'wait 1 sec
Wait 1



' draw a line using PSET X,Y, ON/OFF
' PSET on.off param is 0 to clear a pixel and any other value to turn it on
For X = 0 To 140
Pset X , 20 , 255 ' set the pixel
Next

Wait 1

Wait 1
Cls Text ' clear the text
Loop
End

Hmm, z napajanjem nebi smelo bit problem, saj če ne uporabljaš osvetlitve je poraba majhna... Jaz napajam preko 7805 na vhodu pa usmernik 12V 2A

Upam da LM7805 in ne 78L05. Hja, meni je tole delalo.
Edino vcasih se mi je zgodilo se to, da CLS ni pobrisal zaslona in sem moral uporabiti:
CLS GRAPH in
CLS TEXT skupaj, nato pa mi je LCD "sdas" OK izpisal text nanj...
Torej probaj CLS zamenjat...
