FATFS f_open issue when text file reaches 64kB
Hi all,I'm using an STM32F413 to write to an uSD card via DMA over SDIO. I'm using the FATFS (R0.12c). Up until now, I've been writing to the SD card by firstly mounting, opening the file, write, write, write... then closing and unmounting. I'm writ...
Resolved! H743 QSPI DMA
Hi All,Probably easy question, I would like to use DMA with QSPI (e.g. HAL_QSPI_Receive_DMA) but STM32CubeIDE/MX (1.16.0) is not giving me any options to configure it.There are no options, my parameter settings are belowQSPI is working fine in Indire...
Resolved! Unknown PWM CH2 error STM32F030C8
Hi in custom design arrive problem , that seems as hard to solve. TIM3 CH1 and CH2 config: TIM_TimeBaseStructInit(&timer); timer.TIM_Prescaler = 1-1; //48Mhz/1/2000=24kHz timer.TIM_Period = 2000-1; timer.TIM_ClockDivision = 0; timer....
STM32L496 Determine EXTI wake-source when processor has been put in STOP mode
My project uses multiple different GPIO's configured as EXTI interrupt sources, and there is a point where, after calling the API:HAL_PWREx_EnterSTOP2Mode(PWR_STOPENTRY_WFE)Some different instructions should be executed depending on which EXTI rising...
Resolved! USB issues related to USART speeds -- STM32L072
I've been working on an STM32L072 based project involving USB and USART4. I ran into an issue that puzzled me, so I figured I'd post about it here to help others. If there is a solution to this problem, even better!My original design used USART4 as a...
Resolved! STM32H725/735 max. OCTOSPI clock with Power Scale different from VOS0
Hi,The datasheet DS13311 rev. 5 defines the max. SPI clock for the OCTOSPI only for VOS0, what is the max. SPI clock for other Power Scale settings (I'm planing to use VOS1)?best regardsmartin
Resolved! Vrefint reads as 0 on some boards
I have got 3 identical boards with STM32u5a5. For improving ADC accuracy I want to calibrate Vref using Vrefint. This is working fine on one board, but on the other two boards Vrefint reads as 0 using the same software. Other ADC channels seem to wor...

Resolved! FDCAN interrupt not working
Hello, I am trying to use FDCAN but for some reason interrupt is not triggering. Im using PEAK CAN to send and recieve messages. With osciloscope I can see the data being transfared to the STM board but the interrupt doesn't trigger. The speed I wa...
