Hallo, ich versuche schon seit geraumer Zeit ein Displaytech 64128c http://docs-europe.electrocomponents.com/webdocs/06dd/0900766b806dda2b.pdf , mit der Osama's Lab GLCD-Lib zum laufen zu bekommen. Leider schaffe ich es einfach nicht, die linke Hälfte des Displays anzusprechen! Das ist mein Code:
1 | #include <avr/io.h> |
2 | #include <util/delay.h> |
3 | #include "glcd.h" |
4 | #include "graph.h" |
5 | |
6 | |
7 | |
8 | int main(void) |
9 | {
|
10 | |
11 | PORTC=0x00; |
12 | DDRC=0xFF; |
13 | |
14 | PORTD=0x00; |
15 | DDRD=0xFF; |
16 | |
17 | glcd_rst(); |
18 | |
19 | glcd_on(); |
20 | |
21 | bmp_disp(arr,1,1,127,63); |
22 | |
23 | } |
das der Headerinhalt:
1 | #include <avr/pgmspace.h> |

bin für jeden Hinweis dankbar!! grüße gueee
