I'm using STM32F746ZG and use five UARTs. All UARTs are working fine. Can someone tell me the procedure to change the baud rate on the USART once it has already been initialized? I'm using USART6 a...

I am using the STM32F7-Discovery board and have been stuck at trying to enable the DWT cycle counter. From what I've seen online this should suffice for enabling it: CoreDebug->DEMCR |= CoreDebu...

I am confused with the clock system on my STM32F7 device (Cortex-M7 microcontroller from STMicroelectronics). The reference manual does not clarify the differences between these clocks sufficiently...

I'm using STM32F746ZG and FreeRTOS. The start address of flash is 0x08000000. But I want to change it to 0x08040000. I've searched this issue through google but I didn't find the solution. I chan...

I have configured a UART to receive in DMA mode where the size of the buffer is around 64 bytes. So, basically, the HAL_UART_RxCpltCallback() DMA receive complete interrupt will only fire when 64 c...

I have a project that I have used stm32f746g discovery board. It receives data with fixed size from Uart sequentially and to inform application about each data receive completed, dma callback is us...

I have been measuring clock cycle count on the cortex m4 and would now like to do it on the cortex m7. The board I use is STM32F746ZG. For the m4 everything worked with: volatile unsigned int *D...
