How to use correctly The ADC using the HAL with interrupts on STM32L4 Nucleo board?

We're trying to read from the ADC from 2 channels by using EOC interrupts.When we read the values seems like the channels are wired together.As such we can't distinguish between whether they come from one channel or the other. Here is the code that w...

How to detect that console have just connected to HAL UART?

I need my code called when something connects to the HAL UART.I have a simple mini-debug that just prints something to the UART and I see it on a console connected to the STM debug COM port. I noticed that the HAL_UART_Transmit() always returns HAL_O...

I am working on reading an External 3 bit parallel CMOS ADC (4MSPS)(from MAX2771 board) digital output through STM32H7 board , my only concern if the STM32H7 can handle this amount of samples and save it to pc ?

ADC time spends

Hi All.I am building a function using ADC with DMA.what i did in the while loop is just toggling a GPIO Pin.but it seems that the while loop will be interrupted when ADC is triggered.does it means that when ADC is triggered, while loop will be stoppe...

STM32L432KC ADC DMA overrun in continous mode and circular buffer

Hi, I have several issues trying to run ADC in continous conversion mode with DMA circular buffer. The fact is that is starts to work normally but after a random time adc raise the overrun flag and adc and dma stop running. I´ve tried multiple clock ...
