Hi everyone! I’m working on a project using the Radxa Zero and trying to drive an SSD1306 OLED display via SPI. I followed the architecture guidance from article about building a **new LCD library for Proteus simulation, which helped me grasp how display timing and data handling should work at the hardware level:

I’ve also checked forum threads on the Arduino Forum where users faced SPI flicker issues with SSD1306 OLEDs, and a DigiKey tutorial on stable OLED interfacing. Despite using the same wiring and code, my display flickers or resets intermittently when running multiple GPIO and SPI tasks. Has anyone experienced similar behavior on Radxa boards, and are there known workarounds like isolating power or adjusting bus speed?
