C++ (Cpp) TXSerialfifolevel5 Examples

Example #1

File: SerialSTM.cpp Project: m1geo/MMDVM

uint8_t TXSerialfifoput5(uint8_t next)
{
   if (TXSerialfifolevel5() < TX_SERIAL_FIFO_SIZE) {
      TXSerialfifo5[TXSerialfifohead5] = next;

      TXSerialfifohead5++;
      if (TXSerialfifohead5 >= TX_SERIAL_FIFO_SIZE)
         TXSerialfifohead5 = 0U;

      // make sure transmit interrupts are enabled as long as there is data to send
      USART_ITConfig(UART5, USART_IT_TXE, ENABLE);
      return 1U;
   } else {
      return 0U; // signal an overflow occurred by returning a zero count
   }
}

Example #2

{
   return TX_SERIAL_FIFO_SIZE - TXSerialfifolevel5();
}
