STM32H743 Internal Flash (single sector) going bad

Hi,I had a question with respect to the internal flash of the stm32 chip that we are using. After much investigation, it seems that the erase operation (via the HAL_FLASHEx_Erase_IT() function in software or using the ST-link utility directly) is "sl...

Run two DMAs simultaneously on STM32F407

I am working on a project that uses an STM32F4 disc board to read and write external ADC and DAC with two SPI interfaces. SPI1 (DMA2 Stream3) is set to TX only to write waveform to a DAC, and SPI3 (DMA1 Stream0) is set to RX only to read an ADC. Whe...

Hi everyone, I'm a beginner with MCUs. I want to read ADC values from 12 channels continuously and I'd like to implement an averaging process before transmitting them through UART. I'm using Nucleo-L476RG.

Signals are similar across all 12 channels but I'm confused about how to run the averaging algorithm for 12 channels at the same time. Currently, I can get the ADC values from all 12 channels using DMA without the averaging process.To explain further...
