DataReceiver

Arduino library to provide simple sending of key/value pairs from a computer to the Arduino. (For example: I have a CPU usage value on my desktop computer, and want to use an Arduino to control some lights in response to that. This gets the number to from desktop to Arduino.)

To match DataReceiver (the Arduino side) is data_sender in Python. It depends on pySerial for serial communication.

Example

See examples/ for a quick introduction. Even more briefly:

Python:

sender = data_sender.Sender('/dev/usb.serialmodemfa141')
with sender:
	while True:
		... # Generate a value.
		sender.Send(KEY=value)

		# Maybe handle responses from the Arduino.
		sender.ReadAndPrint()

Arduino:

#include <DataReceiver.h>
DataReceiver<1> receiver; // templated on # keys expected
void callback(size_t size, const char* value) {
	... // do something with value
}
void setup() {
	receiver.setup(); // Serial.begin
	receiver.addKey("KEY", &callback);
	receiver.sendReady(); // once ready to take Serial input
}
void loop() {
	receiver.readAndUpdate(); // read Serial, call callbacks
}
