someone know if it possible to change LPTIM source mux while running? for example to change from LSI to PCLK1? LSI is 37Khz and I want the PWM to run in 1khz so I use count 37, but I want to generate more step then 37 and still remain in 1Khz for PWM

What's wrong with this WWDG initialization code?

Based on the info in the STM32 reference manual, I would have thought this code to start up the WWDG would work (after processor reset). // sets up the WWDG with a period of about 1 sec, no lower limit inline void StartWwdg() { LL_APB1_GRP1_EnableC...

USART Receive multiple characters

Hello,I am trying to recognize a number sent to USART:If I send '123' over USART to MCU then MCU receives only '3' (the last character). Variable recv has uint8_t (unsigned integer) type. How could I receive the complete number ('123')?I am using STM...

how we should configure the gpios using LabVIEW

Hai,I just want to enable the gpio through the LabVIEW using VISA communication, for this how can i make changes in stm32 firmware code to enable the gpio through the labview, if anyone have idea about to how to write the firmware code to access the...

What happens, if in the single-port DMA, DMA_CMARx is overwritten while DMA is enabled?

The description of DMA_CMARx (and also DMA_CPARx) register in single-port DMA (AN2548) says:This register must not be written when the channel is enabled.What wrong may happen if this register is written when the channel is enabled?This of course is ...

SDMMC breaks when interrupted during writing?

Hi,I'm trying to sample data inside an ISR, write it to a buffer, and then write the data in the buffer to an SD card. The SD interface uses the SDMMC devices.It seems that when the ISR interrupts the SDMMC performing a write, the SDMMC errors and re...

NUCLEO-G474RE pwm issue

i am using NUCLEO-G474RE board, TIM1 to output PWM wave, it works fine ,i can see the pwm wave through scope, but when i use HAL_TIM_PWM_Stop(&htim1, TIM_CHANNEL_3);HAL_TIMEx_PWMN_Stop(&htim1, TIM_CHANNEL_3);to stop PWM , there is a attenuated wavefo...

I am using STM32G483CE MCU. I can't find out what will be the default value of DBANK bit in Flash Option Register. In Reference Manual it's default value is given as 0xFXXX XXXX. So which value we have to consider 0 or 1?

Also Which is better option to use Single Bank mode or Dual Bank Mode?I want to upgrade my application via bootloader and at the time of upgrade it is not necessary to continue currently running operation.And In DBANK bit ,description is written as ,...
