I/O monitoring with JTAG/SWD

I would like to monitor in real-time the state of the pins on my board (STM32F407D-DISC1) for a HIL (hardware in the loop) application.To do so I want to use the TAPs of the JTAG. I've found in the AN4989 application note that the JTAG was not suppor...

STM32H743 – DAC with DMA – more memory needed to store DAC tones

hello ST,my question is about the use of DAC with DMA on the STM32H743. I need to be able to store more tunes/tones into memory.The working code is based on an ST sample code, DAC_Ch1_EscalatorConfig(), albeit with many more samples used:HAL_DAC_Star...

Did you ever experiance a situation in which once the controller is powered, it look like there is some short inside the chip and I get a samll hole in the case and the controlle is dead and it is a short to the board ?

Hlo all, i'm trying to receive data over uart and something weird happens every time i try to receive the data, my buf variable always stays empty. can anyone suggest me the solution. I am attaching my code for your reference.

#include <stdio.h> #include <stdint.h> #include <string.h> #include <stdlib.h> //#include "stm32f4xx.h" #include "stm32f411xe.h" #include "uart.h"   #define GPIOAEN (1U<<0) #define PIN5 (1U<<5) #define LED_PIN PIN5   ...

What is proper way to resume DMA after waking up?

HiI searched everywhere but I'm stuck with starting DMA after waking up STM32L053C6U6 from stop mode. Chip displays LCD content, goes to sleep, wakes up by external interrupt on pin, receives SPI data through DMA,sends few bytes at the same time, upd...
