OLED Breakout Board 16-bit Color with microSD not working

Post by jlaiosa »

I doing a project with a Raspberry Pi Pico W running CircuitPython Version 8.04 and the OLED Breakout Board 16-bit Color with microSD using the EYESPI Breakout Board. I copied copied the sample code, it is in the attachments and looked up other examples to figure out the pins. I am using the EYESPI Breakout Board with the adafruit_st7789 library. I checked the pins with a scope and I am getting activity on all the pins except RST which is high. I check all the connections and reinstalled the EYESPI cable. However nothing shows up on the display, it stay dark. I checked and 3.3V is on the EXESPI Breakout Board. All the items mentioned were ordered from Adafruit on Mars 1, 2023, invoice number 3027953.

Any ideas?

Thanks.

John

Post a photo showing your hardware and connections and we'll take a look. 800x600 images usually work best.

Sorry for taking so long getting back to you. I rechecked my wiring again and made sure the flex cable between the ST7789 and the SSD1351 SPI Interface was seated all the way in. I also probe the SPI signals on the on the SSD1351 SPI Interface and there were present. The only signal that was floating was the MISO signal. Is that signal needed for the display? Does not seem to make sense but I don't know. Is it possible the display is bad? The display acts if there is an enable is not set. Unfortunately I took some pictures of the wiring with my iPhone and I having trouble reducing the size of the images. I will keep working on that. I this a popular display? Have you had trouble with it.

Thanks for the help.

Sorry, I meant to ask you in my last post. The display board has a pin for 5V. Do I need to also add 5V to the board in addition to the 3.3V?

Thanks for the help.

Disregard the last question, I was not reading the documentation correctly.

Any suggestion on were to go from here? Can I get a new board/display? Do you have another display that you would suggests? I would like to get this project moving. I did it with plain grey ribbon cable so sending you a picture probably will not help you. I am am experienced engineer with both hardware and software experience so feel confident about my wiring.

Thanks again for your help.

I also checked all the voltages on the display board including the 13V for the display. I also triple checked the connections again to make sure.

Thanks for the help.

I bought another SSD1351 display and wired it to a ESP32-S3 directly to the SPI bus and it worked the first time. I am suspect that that the original display is bad. I am not sure what to do with the original display.
