Option Byte Programming Failed
Hi,We have used STM32F427IIH6 MCU to create custom board. We assembled first proto batch of 10 boards. All boards were perfectly flashing. While testing one board stopped flashing.Based on error message we checked write protection option byte status....
Problem with timer interrupt STM32F427Vit6 (TIM14)
Hi everyone!In my program I have an input which is turning on and off. If the input is not turn on in 3 second I need to detect this. I'm using Timer14 with interrupt. If the input is turn on, the timer is stopped, reseted and start counting from th...
How can I reduce cache-misses in order to optimize the energy efficiency?
I have to deploy an algorithm with a lightweight deep learning-based approach on a low-power STM System-on-Chip based on an Arm Cortex-M-class MCU or Arm Cortex-A-class MPU. Is there a way to reduce cache-misses or a way to reduce the CPU stalls on c...

How to get started with FATFS, USB and HDMI
Hi everyone i am new to using peripherals like HDMI and USB with my applications and i wanted to get started with it but i didnt simply want to go with HAL libraries instead i want to understand the basics of them and how to start from scratch. Also ...
STM32U599 Fail extended calibration when using HAL_ADCEx_Calibration_Start() API
Hello, I am facing an issue when trying to calibrate the STM32U5. I am using the API call `HAL_ADCEx_Calibration_Start()`, SDK Version: 1.3.0.When I run the `HAL_ADCEx_Calibration_Start()` the board hangs and goes off into a limbo state. Even the deb...
STM32H7 Timer Triggered SPI Transfer no interrupts
I am trying to create a repeating trigger to start an SPI transfer to read 12 x 16 bit values from an external ADC.I have configured the SPI with a Rx DMA to receive the data and have created a timer to trigger a second DMA to write to the SPI->CR1 r...
Resolved! STM32F405 - Backup SRAM not preserved
I have a STM32F405 with a coin cell on VBAT and I haven't been able to get the Backup SRAM or RTC to preserve contents when removing main power. The same code works fine on another board that has a STM32F407. //Works on STM32F407 - Fails on STM32F40...
