Resolved! DMA for USART
Hi all,I am trying assign DMA to USART3 channel on STM32MP1.I assigned it appropriately in the CubeMX but it looks like it was not able to auto-generate any code regarding the DMA assignment to the USART3.The device-tree bindings look pretty confusi...
Resolved! PWM Limits for STM32MP1
Hi all,Referring to previous discussion I had.I just want understand what are the PWM limits for STM32MP1.I can't seem to generate PWM signal below 100ms. Any inputs will be appreciated.My target frequency is 1KHz.https://community.st.com/s/question/...
