PiOLED - 128x32 not working

Post by spotdar »

This is regarding the PiOLED that I purchased as a part of the order (Order Confirmation No: 1753086-6216155603).

I was using the PiOLED successfully on both my RPi3B+ and RPiZeroW. I ran all the examples on your GitHub with no issues. Then, suddenly the PiOLED stopped displaying anything. I tried everything but it didn't work. i2cdetect -y 1 showed up the device at the correct address 0x3c on both the Pis. But on running the examples, nothing showed up on the display of the PiOLED. The examples ran with no errors.

I removed the PiOLED from the RPi Zero W pins and connected it using Jumper cables. Still no go.

Suddenly, a day later, the PiOLED again started working correctly. I ran all the examples with no worries and I figured maybe its just a loose connection.

Again. later that day, it stopped displaying. I rebooted the Pi, changed the baud rate for i2c back and forth and enabled i2c on and off but the i2cdetect showed the device correctly but nothing appears on the display.

So, here are the steps that I performed before this problem started:
1. Run stats.py from the examples
2. PiOLED displayed the stats refreshing every 0.1 seconds
3. I CTRL+C'ed the stats.py to end the program
4. PiOLED continued to display the image for the last stat for quite sometime.
5. After an hour, the PiOLED didn't display anything
6. I ran stats.py again but nothing appears on the PiOLED again

Any idea what is going on?

Sounds like an intermittent electrical connection. Can you post a photo of the front and back of the PiOLED (removed from Pi).

Sure, I have attached the photos. Please let me know if you need a more closer picture, this is the best my phone could get a focus lock on the tiny led.

Thanks

Thanks. Those look fine. Can you get one more showing the ribbon cable. It looks like theres some stuff on it? Is it damaged at all?

No its not damaged. That's the smudge marks of an electrical tape that I removed to take the pictures above. Its glue. I can clean it and take another shot of the ribbon cable. It just appears like damage but if you see the picture taken from the back, you can see there is no damage.

OK, so it's not that. Just to make sure I understand - it was intermittent, but now it shows nothing?

Nope, I had my PiOled fixed in a box covered with electrical tape. Pictures below. The smudge is from the electrical tape on the right hand side just above the ribbon.

Sorry for the confusion, on Tuesday the OLED stopped working. On Wednesday, it automatically started working and I put it in the box and covered the box with electrical tape and I took a picture of the black box to show it to my friend. The picture with the OLED in the black box was taken yesterday when it was working perfectly fine until it stopped displaying. Today, I took the OLED out of the box to take pictures for you.

I have attached the pictures of the ribbon from under a magnifying glass after cleaning the smudges from the electrical tape.

My apologies, I misread this question. It was intermittent and by that I mean it would just stop displaying suddenly without even touching it. Then it started displaying again only once and now shows nothing again.
