Hello,I know it sounds like a basic and dumb question but I actually didn't find the answer.I have communication issues between 2 STM32H743 based Nucleos.On the master I use SPI1.If I use SPI1 on the Slave it works fine (repeated send/receive communi...
Hello community,I have a strange behaviour with my timer. Well probably it is not strange but the problem sits between keyboard and mouse, but hopefully you can help me find the cause.following the setup of my program:I use STM32F4 on a self-created ...
Hi,I have a school projet about preventive maintenance on WC. Due to the COVID-19, we no longer have access to the material, but we have to try to continue the project.We use a turbine which is connected to the water access (in the WC) and it will be...
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...
