STM32L072 – LPTIM1 external pulse counting with LSE in STOP mode not working
STM32L072 – LPTIM1 external pulse counting with LSE in STOP mode not workingDescription:Hello,I am trying to configure LPTIM1 on an STM32L072 to count external pulses from a button connected to PB5 (LPTIM1_IN1). The goal is to keep counting pulses wh...
STM32N6 VENC Hardware Handshake with MJPEG encoding
The VENC peripheral on the N6 boasts a hardware handshake path with the DCMIPP peripheral, potentially allowing full compression of each frame to occur with very little active RAM. From what I can find, the DCMIPP capture starts, then the VENC is tol...
Struggling with custom bootloader on STM32L433 (only simple applications work)
I have written a custom bootloader that is running on a Nucleo-L433RC-P board. The application uses USB CDC to call the bootloader and the bootloader uses USB DFU to download the application. I wanted to use USB to call the custom bootloader, rather ...
Infinite loop at startup when optimization enabled.
Our STM32H745XIH microcontroller enters an infinite loop after updating the software with “Release” compilation flags (optimization enabled). This only happens with a specific build, and changing a single piece of code that is definitely not related ...
STM32U5G9J-DK1 MIPI DSI pinout issue
I'm attempting to use a custom LCD daughter board designed to plug onto the STM32U5G9J-DK1 in place of the round display that comes with the DK1. The schematics for the DK1 have a note in read indicating that the DSI_CK_N and DSI_CK_P pins are revers...
Using ADC1 VBAT pin on STM32U535 to measure the battery supply voltage of my system
Hi,My battery (++ LTO/Bucks) that runs everything on my PCBA is connected to VBAT (pin 1). Before the connection I have a voltage divider factor of roughly 1.374, but what I read on the pin via ADC1 channel 18 (what VBAT is routed to internally) seem...
Confusion about ICACHE errata on the STM32U575
The errata for the STM32U575 series includes the following: We would like to use the first option of the 2 listed workarounds (the one that does NOT require disabling and reenabling the ICACHE). Does ST have any implementation examples of this worka...

RTC_ISR.INIT is not quite write protected by PWR_CR.DBP
In 'F427 (and all RTCv2-containing STM32), some RTC registers are write protected: prior writing to them, it is necessary:1.enable backup domain access by setting PWR_CR.DBP2. unlock a RTC write protection by writing two key values into RTC_WPR Break...
