SerialComm

About

This python module simplifies serial communications with an arduino board (https://github.com/Tahitibob35/SerialComm).

Features

• Attach actions to functions
• Simply send and receive strings or integers
• Manage acknowledgments

Examples

1 - Python -> Arduino, without ack

Arduino receiver code

SerialComm s ( Serial );

void remoteAnalogWrite( void ) {
    int pin = 0;
    int value = 0;
    s.getData( "ii", &pin , &value );
    analogWrite( pin , value );
}

void setup( ) {
  s.attach( 2 , remoteAnalogWrite );
}

Python sender script

arduino = SerialComm('/dev/ttyUSB0', baudrate=115200)
pin = 9
value = 120
resp = arduino.sendmessage(2, (pin, value), ack=False)

2 - Python -> Arduino, with ack

Arduino receiver code

SerialComm s( Serial );

void remoteAnalogRead( void ) {
    int pin;
    s.getData( "i" , &pin );
    int value = analogRead( pin );
    s.sendAck( "i" , value );
}

void setup( ) {
  s.attach( 2, remoteAnalogRead );
}

Python sender script

arduino = SerialComm('/dev/ttyUSB0', baudrate=115200)
pin = 5
resp = arduino.sendmessage(2, (i,), ack=True)
values = arduino.parsedata("i", resp)
pin_value = values[0]
