Hi. I'm trying to get a spi oled display working with the pro micro. I've checked connections multiple times, tried tweaking the code, looked up solutions everywhere but no luck. I've had this display working in the past using spi but it stopped working out of nowhere... I thought it was possibly da…

[image] elwango: I try running example sketches from the SSD 1306 library which worked before. This is the code I'm using: If the example sketches are not working, then it's not a code problem. There is no point anyone looking at your code until the display works with the example sketches. Th…

[image] elwango: Adafruit_SSD1306 display = Adafruit_SSD1306(128, 64, &Wire); display.begin(SSD1306_SWITCHCAPVCC, 0x3C); // Address 0x3C for 128x32 You said this was an SPI OLED? There are no addresses with SPI, only with I²C.

Sorry I've tried with a couple of codes and that was one of them but I can't get the 128x64 spi code from the ssd1306 examples folder to work. The screen is entirely black. i've tried with a nano, uno, and the pro micro. This is the code: /**********************************************************…

Please post a hand drawn diagram showing how you wired the display, with clearly labeled pin numbers and designations on both the Arduino and the display. The photo is not very helpful. SPI wiring will not work with the example I2C display code.

Here is the wiring and some code I used with SPI OLED and Pro Micro. Sorry that the wiring may not be very clear, ask if you cannot figure it out [image] Conway's Game Of Life with 128x64 graphic LCD. UPDATE: also with 128x64 SPI OLED Showcase UPDATE: Recently…

Thanks for sharing. I tried to upload and followed your wiring. The error I get is: avrdude: butterfly_recv(): programmer is not responding I have the right board and port selected...

That's an upload error, not related to the code I shared. Can you upload the blink example sketch to the Pro Mini?
