Problems using a 0.96" 128x64 OLED display
Posted: Tue Jan 06, 2026 5:34 pm
I'm trying to use a 0.96" 128x64 pixel OLED display, but I haven't been successful so far.
The pixels on the X-axis seem to work fine, but the pixels on the Y-axis only work up to pixel 55. Any character placed between Y-axis 55 and 63 will not appear on the display.
In the example, I used a square that should be the size of the display, but the lower pixels on the Y-axis have problems (I've attached a photo showing what the display looks like).
I tested an Arduino using the Arduino IDE and verified that the display works fine and the pixels worked fine, but in FlowCode it doesn't work correctly. I used STM32F411CE, STM32F030F4P6 control modules and a Raspberry Pi Pico with FlowCode, and all tests with FlowCode showed the same problem.
I would like help solving this problem.
I am attaching the test flowchart.
