Resolved! Timer -> DMA -> SPI

Hi,      I am having trouble getting the Timer to trigger a DMA -> SPI operation. Namely, I want to set the timer up to run,. Then, get every overflow event to trigger the DMA to move a byte into the SPI. The SPI should auto-send. Then, the cycle rep...

Resolved! USART DMA with LL drivers on STM32H7A3

I've been writing apps using the STM HAL drivers for a while.  I'd like to move to the low level drivers in order to have a better understanding of what's happening in my app.  Comms over a UART with DMA is a critical part of most of my apps so I'm s...

Resolved! STM32L0 -> DMA, parallel operations

Dumb question, can the DMA perform separate, parallel operations with the different channels? For example, could I use the DMA to transmit with the UART and the SPI devices at the same time without one interrupting the other? I'm unclear from readin...

What is the Stm32L4 VDD12

"Hello, while examining the STM32L412C8 microcontroller, I came across the term VDD12. What is VDD12, and can I use the peripherals without making the VDD12 connection? In other words, is it mandatory to make the VDD12 connection?"

One pulse mode configuration

Hello to everyone,I would like to know more about 'one pulse mode'. I'm using a STM32F446RET and I need to generate 1 or more pulses when an event occours.In my project, channel 1 of TIM9 is the pin chosen to generate the waveforms.I got that the 'on...
