main.rar (1.92 KB)
这个main.c 里面含有发送与接受，当有按键时，发送数据，另一个设备接收数据,这个过程是能实现的，问题是如何才能正确显示接受到的数据

当有按键的时候，将 TxPayloadBuffer[]的数据发送出去
SW1_Data_ADDR |= SW1_MASK; // Write a 1 so we can read the switch
      if (!(SW1_Data_ADDR & SW1_MASK))
      {
         // Transmit a packet when the "Switch 1" button is pressed.
         nRED_LED_Data_ADDR &= ~nRED_LED_MASK; // Red LED On
         Delay(DELAY_COUNT); // Give the user a chance to see the LED.
         // This also guarantees the receiver has been running for at least 1ms.
         // Stop receiving so that we can transmit
         RadioAbort();
         RadioSetPtr(TxPayloadBuffer); // Set the transmit buffer
         RadioBlockingTransmit(0, PAYLOAD_LENGTH); // Send it
         ++TransmittedCount;
         nRED_LED_Data_ADDR |= nRED_LED_MASK; // Red LED Off
         // Wait for user to release the "Switch 1" button.
         SW1_Data_ADDR |= SW1_MASK; // Write a 1 so we can read the switch
         while(!(SW1_Data_ADDR & SW1_MASK));
         RadioSetPtr(RxPayloadBuffer); // Set the receive buffer
         RadioStartReceive(); // Restart the receiver
         Delay(SWITCH_DEBOUCE); // Debounce switch
      }

main里面循环检测接受的状态.
      RxState = RadioGetReceiveState();

      if (RxState & RADIO_COMPLETE)
      {
         ReceivedPayloadSize = RadioEndReceive();

         if (!(RxState & RADIO_ERROR))
         {
            if (ReceivedPayloadSize == PAYLOAD_LENGTH)
            {
                  // Successfully received a packet
                  ++ReceivedCount;

                  // Give the user feedback a packet has been received
                  nGREEN_LED_Data_ADDR &= ~nGREEN_LED_MASK; // Green LED On
                  Delay(DELAY_COUNT); // Give the user a chance to see the LED
                  nGREEN_LED_Data_ADDR |= nGREEN_LED_MASK; // Green LED Off
            }


            // else drop Packet. Not the correct length
         }
         else
         {
            // Packet received with an error.
         }

         // Restart the receive operation
         RadioStartReceive();
      }
