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 ...

Resolved! Read 96 bit UDID through serial bootloader or SWD

Hello,I am working on the STM32F103xx. I need to read out the 96 bit UDID (unique device ID) of the devices during production. Is there any way of reading this out from the serial bootloader on UART1 or through the SWD interface? I searched the AN315...

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...
