Hi,I am using stm32L431 and (32.768KHz ±20ppm 12.5pF 70kΩ) as LSE.Every day the time is update by internet, but in some cases, the clock shifting about 5 minutes.It occur aroung 2 times to week. what is probably happening?Binary data format and Alar...
Hello,I am using STM32L073V8T MCU, STM32CubeIDE. My application needs low power consumotion. When some events occurs, MCU move to standby. Than it waits new event for waking up. In other words, my application periodically check new event. After goin...
A STM32F746 on a custom board powered by the step-down regulator TPS62082 by TI doesn't start in about 90% of cases.I flashed (which always works fine) a simple test program, which flashes two LEDs alternately:int main(void) { HAL_Init(); SystemC...
Same question for STM32F100C4T6B, STM32L051R8T6 and STM32G030C6T6
The first image is PWM output when using internal oscillator & The second image is PWM output when using external crystal.
I have a system with several SPIs and logging of data to SD Card. During a test which logged data over night the system ran into a Hard Fault (INVSTATE) after some hours. My questions:What is the reason for an INVSTATE Hard Fault? How can I detect, ...
Hi,we are using stm32f745xx and bellow are our configurations.we are using total 6 timers, out of which we are using TIM6 to generate 50us interrupt.htim6.Instance = TIM6;htim6.Init.Prescaler = 1;htim6.Init.CounterMode = TIM_COUNTERMODE_UP;htim6.Init...
