Previous post: https://community.st.com/t5/stm32-mcus-embedded-software/dma-on-stm32l011f4/td-p/742092 I am working with code on the STM32L011 that uses DMA to read data from USART2. I received excellent help on this forum before and I'm hoping fo...

I'm trying to program an STM32L011F4 to transmit data through USART2 by way of the DMA controller. My code compiles but the IRQ handler for DMA is never called. Either I have not correctly initialized the DMA controller or there is another problem ...

My Nucleo-G031K8 can no longer be programmed using STM32CubeProgrammer or from STM32CubeIDE. When attempting to connect using STM32CubeProgrammer I receive the following text: UR connection mode is defined with the HWrst reset mode Error: Est...

A simple solution and an embarrassing oversight.I finally noticed that I was setting pin A0 (USART2 RX) to AF4 rather than AF0. My code now works correctly. Thank you for your suggests. -A

Are there any specific register values that I should be looking for? If my DMA settings look correct, then maybe I do need to take another look at my USART code. -A

That was a good suggestion. However, I am still not seeing the reason why the code is not receiving incoming data. I must still be a setting with DMA.

Very good question. I should have mentioned that I am able to use polling and interrupts without DMA to receive data from USART2. This proved to me that the hardware is correct. I believe my configuration of DMA maybe at fault and was hoping to hav...
