Hello all,I am very lost and would appreciate any advice. Currently, my final goal is to send an ADC buffer using HAL_UART_Transmit_DMA. But I am stuck on transferring a chronologically ordered array starting from 240 - 289. #define ADC_BUF_LEN 50uin...

Hello,I am struggling to use multiple USARTs. I tested that USART2 works fine but I cannot get USART1 and USART3 to work. If I can't use multiple USARTs at the same time, I would like to use only USART3. However, USART3 does not work. Do I need to ch...

Hello all,I am trying to capture the rising and falling edge of a timer by calling HAL_TIM_IC_CaptureCallback function. I set timer1 as pwm generation and timer2 as input capture direct mode. I am following an example code online. I was able to trigg...

One more question, for value 256 or any values that are multiples of 256 (512, 768, ....) seems to give the wrong value because after 255 (which in hex FF)it should be 256 (which in hex 100) but the one gets ignored (as you can see from the counter 3...

Thank you for your answer!Could you elaborate on what you mean by "arbitrary bytes"? Is it because I did not set the bytes' size?I am using Python to decode on the PC sideAfter the code reads a binarydata = serialPort.readline()*** data looks like b'...

The solution was to connect tx and rx of usart3 to FTDI cable, not rely only on the usb cable connected to the nucleo board

Thank you!The problem was I did not connect a wire between PWM port to IC capture port.
