I don't want to open another topic, but I was wondering if you guys know how to initialize the screen, without using Canon functions.I tried to write stuff in the frame buffer, but the screen is blank, backlight off, and can't see anything. So probably it needs to be turned on some way or another.
But I disagree that CHDK has no need for this, it could be used for all kinds of debugging information, before CHDK is started, maybe for porting new cameras and stuff.
void TurnOnDisplayForStartup(){ asm("bl 0xff993ac4\n");}
Ok, I have another question.Say I want to call a function from the firmware, can I do it this way?Code: [Select]void TurnOnDisplayForStartup(){ asm("bl 0xff993ac4\n");}
MOV LR,PCLDR PC, =0xff993ac4
