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...
Hi, I am trying to learn register programming, so I am trying to write a code for STM32G071rb for blinking LD4 which is connected to Pin PA5 using Registers. But unfortunately not only the LED is not blinking, but also the code stocks in line 43 duri...
Anyone Have Example code for STM32L496ZG Internal Flash read and Write
I would like to use the STM32H730AB as the central controller for a wireless sensing device. For this device, the MCU will drive an external 8-bit ADC at 40 MSPS. This ADC generates an output signal across 8 output pins, 1 for each bit of the digital...
