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...
UM2305 refences this document:AN5893, X-CUBE-STL functional safety package: advanced topics I can't seem to find it anywhere. Any suggestions?
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...
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% & ...
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...
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...
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( ...

Hi.I work on BMS. I want a master-slave topology. I want to use 300 slave cards and 1 master card. This BMS is for automotive. I check ST MCU. I guess, The card should be 10-bit I2C. Because I want 300 Slave cards. So, Can you Help me this subject? W...
Hi, i m reading the general HAL GPIO file, what does the 2 pointers here do? can anyone kindly advise? i see a lot of STM header and device file with these... void HAL_GPIO_Init(GPIO_TypeDef *GPIOx, GPIO_InitTypeDef *GPIO_Init){uint32_t position = 0x...
