128x32 OLED display won't turn ON

Post by jordenc »

Having a little bit of trouble with this display. I have it connected to a pic16f690. I'm just trying to turn the thing on. As far as i know, I have the appropriate SCL, SDA lines connected. I have the VIN connected to 5 volts. When I send the start sequence, device ID, I get an ACK back, so I would think its working... but after sending:
start,
device ID,
control byte,
0xAF (turn display on),
control byte,
0xA5 (turn entire display ON),
stop.

I get nothing turning on. Any ideas what could be happening? I am new to I2C, but I am pretty sure I am getting an ACK back from the display because the SDA goes low while the SCL pulse is HIGH on the 9th cycle.

Please post clear, detailed pictures of the module, showing your soldering.

You want to see my soldering of the 6 header pins to the module? Those are the only soldered lines here. Not sure why that is relevant?

I understand. Well I did solve the problem. Ended up finding some code for a PIC running an SPI interface, and doing some tweaking for I2C. Got the screen on and everything is good now. If anyone else has problems integrating it with a PIC send me a message.
