I had the same problem when using the EPSON version of the screen. When i initialised the screen it comes on with a dull golden glow. I solve my problem by adjusting the voltages to the LED+ pin (pin 10). My volatage was too high making the contrast too high so I couldn't see any changes to pixels. Lower voltages should help. |

It is already about year since I last worked with these displays so I don't remember anymore how things exactly work. To refresh my memory I would have to read the datasheets again. But these links posted earlier look like they would have some nice example code to use and see how the initialization and other things work. http://www.deramon.de/nokia6610lcd.php http://www.apetech.de/nokia6100.php I will bookmark these for myself to have a closer look when I next time work with these displays. |

hi! Henri, ive a problem with mi library, when i send an image to the display, that is my result 
As you can see, the img ist complete, the functions are this: void gclcd_img(void) { gclcd_setarea(X_START, X_END, Y_START, Y_END); gclcd_cmd(MEMWRITE); for(i=0; i<(PIXELX*PIXELY)/2; i++) { gclcd_data(imagen[i]); } } imagen code: static const unsigned char imagen [19200]={ 0x42, 0x4D, 0x3E, 0x47, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x36, 0x04, 0x00, 0x00, 0x28, 0x00......... continue until 19200 hex values... Thnks! |
