I figgered it out. Can fill and clear screen, cant get single pixels yet…
[code]
//-----------------------------------------------
void readid(void){
//read id = 7
unsigned char id;
twistart(); //send start
twiadr(0x78 + 1); //adr + read bit
id = Get_byte_and_NACK(); //read id byte from oled
twistop();
cprintf(“id %02x\n”,id);
}
[/code]
