Posted on December 24, 2015 at 08:31Hello All,
I try to send an uint8_t array over SPI with DMA, but the microcontroller going to hard fault handler. The C code is generated by STM32cubeMX.
My source code is:
/* USER CODE BEGIN 0 */
&sharpdefine meret 100
uint8_t spitx[meret];
/* USER CODE END 0 */
int main(void)
{
/* USER CODE BEGIN 1 */
/* USER CODE END 1 */
/* MCU Configuration----------------------------------------------------------*/
/* Reset of all peripherals, Initializes the Flash interface and the Systick. */
HAL_Init();
/* Configure the system clock */
SystemClock_Config();
/* Initialize all configured peripherals */
MX_GPIO_Init();
MX_DMA_Init();
MX_SPI1_Init();
/* USER CODE BEGIN 2 */
for(uint16_t i=0;i<meret;i++)
{
spitx[i]=127;
}
HAL_SPI_Transmit_DMA(&hspi1,spitx,meret);
/* USER CODE END 2 */
/* Infinite loop */
/* USER CODE BEGIN WHILE */
while (1)
{
/* USER CODE END WHILE */
/* USER CODE BEGIN 3 */
}
/* USER CODE END 3 */
}
Can someone help to me?
