STM32CubeMX + CAN + HAL

I have a STM32F373VCT6 MCU with CAN bus connected to PD0 and PA12 pins. I also have an old project which have these pins configured by hands and CAN bus works properly for this project. Now, I need to create new project for this MCU and I try to do i...

Empty STM32L4R5 (with factory default settings) will try peripheral boot through system memory no matter what (bug?). PA9 then becomes output (as USART1_TX). Shall we use a resistor for VBUS?

Strangely an empty STM32L4R5 will try to boot from system memory and then will try all peripherals turning GPIOs to outputs while trying. Of course this is very dangerous if not taken into account in the design of boards that are to be started with "...

UDP echo server stress test crash in RTOS - but succeed in bare-metal

Hello,In STM32H743 there is echo udp server test. We test it using stress test from PC (sending udp)It behaves very well, without any issues.We than moved to LwIP_HTTP_Server_Socket_RTOS, and added the udp echo test there (we need the udp test runnin...

Can semaphore in FreeRTOS be used for triggering less than 1ms ?

Hi, I wish to use FreeRTOS to create task with semaphore to wake up the task for every 2kHz. I know FreeRTOS timer tick is 1ms (1kHz) the most. I create a HW timer to interrupt every 2k. Question, is the semaphore and the task able to be woken up eve...

STM32H7 USB driver fails highest optimization (-O3)

People (and me) 'complain' about, compiling a project with USB HAL drivers with highest optimization (GCC with -O3) does not work. You had to fall back to -O2.Sure, I found the reason and easy to fix:The low-level driver, file 'stm32h7xx_ll_usb.c' ha...
