Hello,
I'm working on a project involving a 3-phase inverter circuit. My goal is simply to design a 3-phase inverter circuit capable of delivering around 200 watts. I'm sharing the circuit and the code I'm trying to implement below. I'm planning to use an STM32 as the microcontroller, but I'm encountering multiple errors in the main.c file when working with STM32CubeIDE. Is there a better approach I should follow, or could you help me identify the issues in the code?
