Stuck in sleepmode
I tried using the sleep mode in STM32L053R8, it gets stuck in this condition. what is the reason. if((ulpbit != 0) && (vrefinbit != 0)){SET_BIT(PWR->CR, PWR_CR_ULP);}

STM32G474VET3: comparator characteristics
Hi, The propagation delay and offset error mentioned below for integgrated comparator. Can it be changed at higher temperature at 125 Deg c. So what will drift in propagation delay and drifts of comparator value at higher temperature lets say at 125 ...
Resolved! I2C Interrupts
I want to know the difference of the below 4 cases. Why the results are not as expected. Stm32 board is an i2c master with speed of 400kbps and slave is software simulation using Aardvark Total Phase Control Software.uint8_t i2c_tra[10] = { 0x1, 0x2,...

HiI successfully got USB DFU bootloader running based on this video.But one question: why is FLASH_PROGRAM_TIME 50 ms?How is this value dervied? What is the minimum possible value?Thx.
Resolved! STM32F769, generate a 2kHz clock on PC9.
Hi,I'd like to have a 2kHz clock source on PC9, I was wondering if I can use TIM3_CH4 or TIM8_CH4 to do it. May you please help me to figure out it? My question is how to generate a 2 kHz clock on PC9 if I would like to use TIM3_CH4 or TIM8_CH4? Howe...
Debugging problems on STM32G0B1 Nucleo board in conjunction with flash memory erasing/programming
I have a very strange behaviour when using the (on-board) ST-Link debugger on the STM32G0B1 Nucleo board using the Flash Programming example contained in the STMCubeG0 package (v1.5.0).I use Keil MDK IDE v5.36, CMSIS- & STM32G0 device support package...
STM32 microsecond delay function with polling method
Hi,I am using stm32f0. I try to microsecond delay function. But, I observe that TIMx->CNT not increasing.I probably mistake on configutration function. But I could not solved. In 29 line, UF flag not to be setHere is my code; void ledconfig(){ GP...
Resolved! How to debug Stm32H755 Cm4 Core to get SPI clock running.
Hey Everyone, I am having an issue with the stm32h755 dual debugging. Im trying to run cm4 by itself without cm7. But the issue im having is, whenever I reset the MCU and check the SPI lines, I see a clock running. When I debug just cm4, I do not se...
