Posted on December 20, 2015 at 14:56Hi !
I need to implement a Rx-uart at 250k bauds with variable length but the problem is that I'm with the CubeMX configurator and I don't know how to do it.
I was also trying to receive the data in DMA but when I call HAL_UART_Receive_DMA, I receive a 0x00 at the first byte but when I call HAL_UART_Receive_IT at the same place, I receive the byte I need. (0xCC)
If someone can help me...
Here is some code :
void HAL_TIM_IC_CaptureCallback(TIM_HandleTypeDef *htim)
{
if (htim->Instance==TIM2)
{
if(HAL_TIM_ReadCapturedValue(&htim2,TIM_CHANNEL_2) >= 176)
{
HAL_UART_Receive_DMA(&huart1,data_rdm_discovery,38);
}
}
} /*when I have a break of 176 us I call HAL_UART_Receive_DMA(&huart1,data_rdm_discovery,38)*/
Then I analyze the packet with the rxcplt_callback
#hal #uart #!stm32 #stmf1
