SerialPipe

Bidrectional peer to peer library

This is a simple bidirectional communication library in between two microcontrollers. So, the main advantage of the library is that any microcontroller can send data to other microcontroller like send(opcode,data) and the other microcontroller send acknowledge if data packet is valid. Depending on the opcode the microcontroller can interprete the data and performs different actions.

Sender Example

int opcode  = 10;
char data[] = "Sample data block"
pipe.send(opcode, data);

Receiver Example

char readBuf[100];
int opCode = pipe.getOpcode();
if (opCode > 0)
{
    switch(opCode)
    {
        case 10:
            Serial.println(pipe.read(readBuf));
            pipe.ack();
        break;
        case 12:
            //perform different action
        break;
    }
}

Internal Library Opcode

The user cannot use opcode 0 to 9 for normal transaction. These opcodes are used by internal library

• 1 -> for connection check

Library Tested with
