Hi All,I am successfully programming and debugging a NUCLEO-STM32F401RE by its embedded ST-LINK programmer using STM32CubeIDE v.1.12.0 on a computer running Ubuntu 22.04.3 LTS, updated and upgraded.I have a second PC running exactly the same Ubuntu, ...

Hello,I have configured a CUBE IDE project to match a Nucleo-F401RE board to measure the system clock pulses (at 84MHz) between to consecutive rising edges of an external signal applied to pin PA3 (which is Timer2 Channel4 input).The Input Capture in...

I have a transmitter over USART and an STM32H7 receiving data. The transmitter always writes N bytes at a slow repetition rate, i.e. every 1 second or more.Once N data are received by the STM32H7, for example using interrupt, the function HAL_UART_Rx...

I wish to build a classical closed loop controller based on a STM32H743 interfaced via SPI to an external 16bit ADC and to a 16bit DAC. The MCU is supposed to read an ADC sample, feeding a controller routine (for example implementing a standard PID c...

Thanks for your comment: despite it was not a bad port, it forced me to try "lsusb" thus throwing a symbol-not-found error. After googling about this error I found that for some unknown reason an extra libusb file was present in folder /usr/local/lib...

Thanks waclawek.jan, that was the issue (since the beginning), i.e. using blocking calls inside the ISR. After removing them, the original code as well as the latter work as expected.Thanks for your support,Marco

I have checked the register and compared with those of the STM32L431, as far as I can argue, they are just OK. Then in the IDE I moved the input capture function from channel4 to channel1 and the interrupt started firing.Since I need two channels, th...

Many thanks for your answer.I will go through the indicated hints, but in the meantime I post the relevant main and tim code.This is the main.c:/* Private macro -------------------------------------------------------------*/ /* USER CODE BEGIN PM */ ...

Thanks to Tilen and Paul for answering with great suggestions.Tilen, the full-featured DMA approach is a great piece of code, thanks for sharing it. The approach of polling in a thread new-data arrival, provided that DMA takes care of storing them wi...
