Hi to all,I'm trying to write my own I2C class, but SDA seems not willing to collaborate.Here is pins configuration:#define I2C1_SCL 8 // PB8#define I2C1_SDA 9 // PB9MYI2C::MYI2C(){ if(!(RCC->AHBENR & RCC_AHBENR_GPIOBEN)) RCC->AHBENR ...
I am working with stm32H743 MCU, sometimes when I add a function, its calling caused a hard fault, when I move the function to another place in the code, the fault is resolved.What can be the reason?
I have a strange issue. I use printf function in a uart port for print some variables that I use in my code. This works perfectly in cortex m4, but now in cortex m0, the variable printed show me 0, in the next code:uint8_t flash_ext_init(void){ ui...
I almost migrated all my code from Hal to LL and I am really happy for the execution improvent and better size footprint of the code.However, I can not find a way to make/get a equivalent function as hal_gettick provide me. Usually I use state machin...
I set these as GPIO outputs, but turning them on seems to be ignored. I read somewhere that LSE should be off to use these, and it is turned off, as I can see it in STM32CubeMX.Is there something else I need to do to use these 2 pins as GPIO outputs...

A follow-up to this thread - for stm32L433 (Cortex-M4F):https://community.st.com/s/question/0D53W000014wcE5SAI/how-to-get-segger-rtt-to-work-with-sleep-modes-on-stm32Like that thread, I already have DBG_SLEEP, DBG_STOP, and DBG_STANDBY set - but the ...
I have tried to setup a minimal project where I configure the P-NUCLEO-WB55 board to trigger an interrupt (falling edge) when I press a button, that will toggle the blue LED (L1). I tried buttons SW1, SW2, SW3, all have the same problem: when I press...
Posted on October 25, 2017 at 11:53Hi all,I am using STM32L433, and checked the manual that it supports rx timout for the uart. I am using cubeMX v4.22.1 with Cube L4 firmware Package v1.9.0. I try to receive unknown sized data from UART3 but i do n...
