Hi,I'm working on a custom board based on STM32L486 MCU, the microcontroller will stay most of the time in standby and will wake up using a physical button connected to SYS_WKUP3. This to say that the overall board consumption have to be as low as po...
Hi All,I want to use timer 1 for my double pulse test. To start with though I want to get it going in a simple PWM mode at first.I have gone trhough the reference amnual several times and looked at the block diagrams. I have got the registers intial...
MCU sets FLASH->SR bits: PGPERR and PGSERR all the time even immediately after it is cleared. It causes a problem with erasing flash memory. I am using RTOS(TIM1 as a base), Timers and Systick as well but I think those shouldn't be a problem.Code is...
Hi all, I'm running an application where I got to initialize an UART (by interruption) transmission at power up . So I'm a initializing like this : HAL_UART_MspInit(&huart5); MX_UART5_Init();There are the basic functions from STM32 Cube MX... When th...
I'm writing a firmware on a STM32F429ZI Discovery board. The firmware runs on Flash bank1 and erases/programs Flash bank2. When I try to erase or program bank2 the error flags PGPERR and/or PGSERR will be set without any plausible reason.Example:FL...
The MCU I use is STM32F103C8 and I need 2 PWM signals that complete each other to %100 duty cycle. ( ie: PWM1=%60 and PWM2 =%40 ). When one PWM channel is high the other one needs to be low and vice versa.The important part is, these two PWM signals ...
Hello I have NUCLEO-G474RE running at 170Mhz (24Mhz HSE [div 6] [mul 85] [div 2]) .I am using Master and TimA $ TimC hrtimer as PWM for SMPS running at 100kHz (10uS).I want to check how much available time for me if I interrupt every period and updat...
Hi Expert,I have an question about the clock config when I would like to printf via the SWO, below is my current config, but I don't know where are needs modify:Here have two SystemClock_Config function [1] and [2]:About the [2]: I from the STM32Cube...
The manual says the data received will be right aligned in the SAI_DR. Does this mean the data will be automatically shifted right if my data size less than the slot size. For example, a 24-bit data size with a 32 bit slot size? If so, how it treat t...
Hello,I know, this problem might require a careful look into the code but I would like to ask for advice about where to start from.Basically my problem is that the code does not enter in the while(1). I have the impression that this problem arised wh...
