I've created a single pulse that executes for about 150ms. When it's complete I was expecting HAL_TIM_PWM_PulseFinishedCallback() to be called, however, it never is.Doing this:if (HAL_TIM_OnePulse_Start(&htim1, TIM_CHANNEL_1) != HAL_OK) { /* Starti...
Hi there,I want to do a printf redirected to a Tera Term using the USART2 on the STM32F407G-Disc1, but it doesn't print while the same code works on the NUCLEO-F401RE. I found this instruction in the user manual UM1472. Does it mean that I have to u...
Hi guys,I am struggling for a few days with the MAX31850K (Cold-Junction Compensated, 1-Wire Thermocouple-to-Digital Converters) so I was hoping that some of you might have experienced the same issue.The chip is soldered on my custom PCB (I am not us...
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...
The PDF, which contains the link is called STM32U5_Application_Development_Workshop_Installation_Procedure.pdf. See page 34 of 49.
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 ...
