Hello everyone, I write here to know if someone can help me,how to be sure the systick value is good ? be sure that 5 seconds are well done ?thanks to help me !

STM32 Infinite loop when Interrupts are enabled ( REPOST since my previous one doesn't load it seems)

Hi everyone.So my previous post just did not load for some reason.The problem is that for some reason I get this issue when I debug once I enable the interrupts.I am simply trying to respond on the TIM5 interrupt but I get thrown to a part of the fil...

STM32F401RE goes into infinite loop when interrupts are enabled.

I am not sure why but the moment I enable this interrupt the debugger goes to this file and just sits there. What is interesting is the stack trace changes if there are certain functions involved but the error never changes. So I removed all the func...

I would like to know if there's any example and documentation on how to use the accelerometer in this board.

STM32F401 plus VL53L1X crashes after 10 mins

Hi Guys,I'm using an STM32F401 board, accompanied an expansion board, and by a VL53L1X (people counter) sensor. It works for 10minutes then the board crashes and the only way to get it working again is by resetting the board.Hi Guys, What I'm usingST...

stm32l010 analog watchdog

Can the analog watchdog work with oversampling? If so, will it monitor only the converted values after a full oversampling cycle?

unexpected reset after changing the GPIO mode on Fly.

Dear experts, my STM32F042G6 is unexpectedly reset after I switched on fly CAN_TX GPIO to output GPIO pin. for this I did this steps.1).HAL_CAN_STOP() and then 2). GPIOA->MODER &= ~((U32) "pinX"); GPIOA->MODER|= ~(U32) "pinX");I have also made th...

Cannot use SPI TSIZE in Simplex receive only mode on STM32H7 ?

A question about this sentence of STM32H7 reference manual:Receive-only mode: COMM[1:0]=10In master mode, the MOSI output is disabled and may be used as GPIO. The clocksignal is generated continuously as long as the SPI is enabled and the CSTART bit ...
