I have configured CAN module 1 on the STM32F412 and it works fine when initialized with a certain BAUD rate (For example 500K). I have a GPIO input, which when toggled needs to changed the BAUD rate to 250K. The sequence I am following with STM32Cube...
I got the CAN bus on the STM32F412 with STM32Cube_FW_F4_V1.25.2 - up and running but I have noticed that the Initialization configuration requires the filter to be enabled and configured properly. If the filter is not configured and enabled, the CAN...
Hello everyone,We are using STM32G070 on a prototype board which will be in production soon. My problem is that when the board comes from the subcontractor, we can't program the microcontroller from UART. We succeeded to program it from UART after us...
Currently, I am facing an issue with synchronization between ADC and DAC.ADC and DAC are both configured to use DMA1 in circular mode. ADC and DAC are both triggered by TIM4. I enable TIM4 right before main loop and observe perfect synchronization be...
I am unable to clear the EXTI pending register it always stays high and probably that is what is causing interrupt to trigger again and again. I am attaching snippets of code .Please Help me figure out the issue . #include "stm32l0xx.h" ...
Hi, i am controlling my stepper motor by giving commands through modbus in stm32f103. I am able to drive motor in one direction . But i am not able to drive my motor in another direction by sending command through modbus. can anyone please help me...
Hello,I am trying to get a simple GPIO toggle working with the NUCLEO H743ZI board. I noticed that when I try using the GPIO port F pins, even though the port registers are configured correctly and I can see the bit changing in the GPIOF_ODR register...
I use STM32F407IGT6 as a SPI master.I use SPI in interrupt mode with HAL_SPI_TransmitReceive_IT(). In ISR HAL_SPI_IRQHandler(), hspi->TxISR(hspi); is always executed while hspi->RxISR(hspi); is never executed.I traced down in HAL_SPI_IRQHandler().wh...
I'm using a Nucleo F746ZGThe SPI is setup in RX only slave mode and uses DMA Double buffer mode. The data rate changes, but at max I should be writing right at 126 kBytes per second to the drive. I'm using fatfs and USB driver with the cubemxide sou...
I am using STM32F746G-DISCO board. And want to store all my variables in .data section instead of .bss section.This is just to make enough space available in .bss section for my DMAs.My question is that how can I do this? Can any one give me some ref...
