What's wrong with FMC seventh family
LCDHi all. I can’t figure out how to work in LCD interface mode. I check it with an analyzer and see that when writing a byte, instead of one FMC_NWE pulse, several are generated.

Resolved! Input signal when MCU is powered off
Hello,I will make some probes for reading electrical values (AC, Analog, digital,...), but I'm not sure what happens if I insert a signal to a GPIO when MCU is powered off.I read time ago that all GPIOs are in high impedance state when MCU is not pow...

While single stepping in Cube, debugger disappears into an ISR and won't return
Hi,I'm runningSTM32CubeIDEVersion: 1.9.0Build: 12015_20220302_0855On Linux and it's started misbehaving while trying to debug while single stepping through code.Ican get one or two steps in and it jumps off to USART3_IRQHandler and won't come back ou...
HRTIM G474RE
Hello everyone ,I have a Project where i wish to have a 8Mhz PWM pulse. For this i use the HRTIM timer at 4.9Ghz with a period of 600I have my PWM output but it seems that i can't set 0% duty cycle ? in fact duty cycle seems to not work between 0% & ...
stm32g0b1 swd interface not working
Hello community,we made a nice project with TouchGFX and STM32G071C8. We needed increase flash memory. We change mcu to STM32G0B1CE. I cannot this mcu programming over SWD. I use various STM ARMs, has never been such a problem. I test two new mcu wit...
Unexpected MCU (Microcontroller Unit) behavior during programming
Hello, I'm using an STM32F411RE MCU to control a DC motor driver, and I'm encountering an issue. Whenever I program the microcontroller using the STM32CubeIDE software, the motor starts operating.This occurs even when I connect the electronic board t...
STM32L4 mute mode using address mark detection
I am using STM32L4P5 or STM32L4R9 microcontrollers and want to implement multiple-processor serial communication with 9-bit data length.As indicated by the following picture from the RM0432 reference manual, MCU will go into normal when address bit( ...
