UART Stream Library

This library implement Stream over UART based on STM32CubeMX HAL Driver

How to use

Following instructions shows how to use it for USART1

1. Configure UART in CubeMX and generate the code

   UART Must be in IT or DMA mode

2. Define your UARTStream variable and initialize in main after UART init

   Global Area

   uint8_t rxBuf1[128];
   uint8_t txBuf1[128];
   UARTStream uart1;

   Main Function

   UARTStream_init(
       &uart1, &huart1,
       rxBuf1, sizeof(rxBuf1),
       txBuf1, sizeof(txBuf1)
   );

3. Add UARTStream handle into callbacks

   void HAL_UART_RxCpltCallback(UART_HandleTypeDef* huart) {
       switch ((uint32_t) huart->Instance) {
           case USART1_BASE:
               UARTStream_rxHandle(&uart1);
               break;
           // you can add more UART here
       }
   }
   
   void HAL_UART_TxCpltCallback(UART_HandleTypeDef* huart) {
       switch ((uint32_t) huart->Instance) {
           case USART1_BASE:
               UARTStream_txHandle(&uart1);
               break;
           // you can add more UART here
       }
   }

4. Start receive stream

   IStream_receive(&uart1.In);
