STM32H7 SPI DMA only works when breakpoint is set in debugger

Hi, I have a custom board based on the STM32H745 and I'm trying to understand an issue I'm experiencing with the SPI Interface. I have a BMP280 attached to SPI1 on the M4 coreand I've successfully written a driver for it both using DMAs and Interrup...

On 'F407, RTC Backup Registers cannot be read using SWD if RDP Level 1 is set

In STM32F407 locked to RDP Level 1, with a battery on VBAT, I keep some (not critical) data in the RTC Backup Registers. In an attempt to investigate an incident, I tried to read out content of these registers using SWD. While I was able to read RTC ...

Resolved! USART 2 Transmit not working

Board : STM32F746GI configure USART1 with same configuration. USART1 is working fine. I did same configuration for USART2 also, but USART2 not working. I don't know what's happening.Thanks Manikandan D

Push button: is there a need for software debouncing?

Hi. I am trying to trigger and external interrupt using a push button (rising edge trigger and use internal pull down). When the push button is pushed, the variable cnt should be incremented and the pulse width of the PWM shall be changed according;...

Incorrect RTC operation in STM32L073CZ

Good afternoon.I have developed a device for collecting data from sensers and storing them in external memory.During testing, I revealed a failure in the operation of the device.Investigation of the behavior showed that there is an error in the RTC o...
