OLED testing && waiting for the proofing to come back [Copy link]

        I was tired from the business trip these two days. I feel dizzy after sitting in a car for a few hours because I am old. To summarize the work of these days, I first tested I2C to drive an OLED screen. I just glanced at the document. I dare to do this thanks to the code summarized by the forum friends before. Thanks again @ljj3166 for the link https://en.eeworld.com/bbs/thread-925896-1-1.html. So I only put my test pictures here. The initialization, read and write codes of I2C are basically copied, but the unused storage addresses are changed. Then I drew a PCB top board, which is the same size as the GD32F350 bottom board and is directly connected through pin headers. Its main function is to adjust the brightness of a 4-way LED light source. The hardware block diagram is as follows: The schematic screenshot is as follows: (I prefer to draw the schematic on one sheet without paging , so the screenshot may be blurry, but it’s not technically difficult anyway) Then it’s the PCB. I just placed the order today so it’s definitely not that fast. I’ll put a 3D simulation picture below: Finally, here’s a photo of me in Huizhou during my business trip. I had a little fun while suffering from motion sickness.

The schematic is too blurry, can you share it...

You can find a lot of schematic diagrams of OLED modules on Taobao or Baidu.

OK, thanks
