We encountered an issue with the SPI3 peripheral on F4xx and F7xx series chips where the RXNE bit of the status register would be set right after enabling the SPI peripheral after re-configuring it.This is clearly impossible as no transaction is perf...
ADC polling of multiple channels
Hello,After setting up a 4 channel read with DMA, I ran into the problem, that the value of the internal temperature sensor seemed to not change at all. The values of the read out potentiometer however were plausible.So I wanted to check all used cha...

Measure STM32F373 core temperature
Hi,I was measuring the STM32F373 core temperature.It seems that the core is 56°C while the environment is 23°C, no housing.Is the 56°C a reasonable temperature? It looks quite high to me.I used the settings below:
Resolved! Mixing HAL and Direct Register Manipulation
Hello. I am writing a code to read ADC data from an AC voltage sensor. I used HAL to initialize ADC 1 and USART2 for checking the values in Putty. However, I would like to use direct register manipulation to send data to USART6 so that it can transmi...
