I'm checking if there is any known conflicts between UART3 and M1PWM2.
Configure UART3 and output data on the TX pin. Scope confirms output.
Then configure M1PWM2 to generate a ~300kHz 50% signal, no interrupts, just the output signal. Scope confirms output.
However, now no signal is output on UART3 TX.
UART3 is on GPIOC. M1PWM2 is on GPIOA, PA6. Don't see how they can interact.
Is there something I don't understand?
