We're porting some existing working code to the STM32G031J6M6. On pin 5, we are using TIM3CH3, and passing high time data from an 8 bit array to the 16 bit CCR3 register, and the waveform is as expected - correct.On pin 4, we are using TIM2CH1, and p...

Thanks for the reply.The code that we used for TIM2CH1 was a tight loop, polling the registers (the execution time of the standard STM drivers is too long in this instance)In the end, we have removed the TIM2CH1 code and used TIM3CH3 and TIM3CH2. TIM...

Thanks for the reply.I took a look at the DMAMUX, and ruled it out by writing a loop that updated the CCR1 register when the channel 1 flag was set in the SR. The result is the same.The reaction looks as if the CNT register is sometimes not resetting...
