示例代码：
#include <PJON.h> // Transmitter board codePJON network(12, 45); // Bus connection to pin 12, device id 45void setup() { network.send(44, "B", 1, 1000000); // Send to device 44, "B" content of 1 byte length every 1000000 microseconds (1 second)}void loop() { network.update();}/* ---------------------------------------------------------------------------- */#include <PJON.h> // Receiver board codePJON network(12, 44); // Bus connection to pin 12, device id 45void setup() { network.set_receiver(receiver_function); // Set the function used to receive messages};static void receiver_function(uint8_t length, uint8_t *payload) { if(payload[0] == 'B') { // If the first letter of the received message is B digitalWrite(13, HIGH); delay(30); digitalWrite(13, LOW); }}void loop() { network.receive(1000);}
