Protection against HRTIM output locking high

I am using an STM32G474 to create an inverting buck-boost converter, but after damaging a few boards, I realized that there is a series design issue that could short 24V to ground through an inductor if the HRTIM output pin ever goes high unexpectedl...

Resolved! Excessive MCU heat after debugging

I have a design that uses two HRTIM outputs from an STM32G474 MCU to provide a PWM signal to two external half-bridge gate drivers to drive two DSMPS, a buck converter and an inverting buck-boost converter.  After several debugging sessions, the MCU ...

STM32L562 Using TIM1 to trigger ADC1 Ch1 sampling at 5 kHz with DMA1 storing to a circular buffer. Stores 12 samples, then no further samples stored. What can stop this chain from functioning?

Here is the setup (Using timer 1 - 16 Mhz clock, counter = 3200) using OC channel to produce scope signal on output pin):void MX_TIM1_Init(void) {   /* USER CODE BEGIN TIM1_Init 0 */   /* USER CODE END TIM1_Init 0 */   TIM_ClockConfigTypeDef sC...

STM32F4 discovery timer and dma sampling

Good evening to everyone,I'm trying to sample various signals, both low frequency and high frequency. For the low frequency, I'm using a timer, while for the high frequency, I'm using DMA. I would like to perform read scans with the ADC, selecting th...
