Hey, I'm having some issues with setting up clocks for my STM32F411CEU custom board with HAL.Using PLLCLK from HSI ends up with Hardfault, around where RCC is being configured.The only way I don't get hardfaults is:1) if I set System Clock Mux to HSI...

Hello, I am trying to send a message using SPI DMA. I also enabled UART DMA. When both of them are executing, SPI DMA does not work. I implemented SEmaphore Mutex as well. Below are my code and SPI and UART drivers. Can anyone help me --------------...
I'm using an STM32H747XI Discovery board for testing. I seem to have the opposite problem of everyone else, my DTCM value is NOT clearing upon losing power. I have the following in my LD script: MEMORY { ... /* Put NOINIT at the top of the DTCM bloc...
I am transfering data array from an array to PWM register of TIM1.int16_t sin_table[20]= { 0, 39, 77, 113, 147, 177, 202, 223, 238,247, 250, 247, 238, 223, 202, 177, 147, 113, 77, 39};HAL_TIM_PWM_Start_DMA(&htim1, TIM_CHANNEL_1, (uint32_t *)sin_table...
Hello everyone!I have a problem with filling the buffer with data when I receive it via UART using an interrupt. I use a microcontroller of the STM32G03 series. Packets are sent at a frequency of 4 times per second. As a result, the buffer is filled ...
Hi STM32 enthusiasts, I’m reaching out to the community for advice and guidance on an issue we’re facing while developing an external loader for our custom board. We’ve been working with the STM32H730IBK6Q chip and an external memory MX25LM51245GXDI0...
Hi I want to understand Rx message process in case of can2. Rx fifo code I have tested when I used only CAN1 it is working fine. I have put RxFifoMSgpendingcallback function in IRQhandler and further code is working fine for when I used only one (CAN...
Hi all!I have NUCLEO stm32G474RE board, and I am playing with HRTIM.I am trying to take advantage of fault logic, found in HRTIM module.HRTIM can have GPIO hardware input, which can shut down all HRTIM outputs, without any software overhead.Now, I wo...
Today, for the first time I tried to set up RTC alarm using STM32U5G9 MCU. I need RTC alarm (IRQ) to fire on every second change, that is, when subsecond counter is zero - it is configured to count 32kHz clock pulses from 32k to 0 using 15-bit subsec...
