J'ai pris les examples dans la librairie XBee.
Du côté émetteur on a:
#include <XBee.h>
/*
This example is for Series 1 XBee
Sends a TX16 or TX64 request with the value of analogRead(pin5) and checks the status response for success
Note: In my testing it took about 15 seconds for the XBee to start reporting success, so I've added a startup delay
*/
XBee xbee = XBee();
unsigned long start = millis();
// allocate two bytes for to hold a 10-bit analog reading
uint8_t payload[] = { 0, 0 };
// with Series 1 you can use either 16-bit or 64-bit addressing
// 16-bit addressing: Enter address of remote XBee, typically the coordinator
Tx16Request tx = Tx16Request(0, payload, sizeof(payload));
// 64-bit addressing: This is the SH + SL address of remote XBee
//XBeeAddress64 addr64 = XBeeAddress64(0x0013a200, 0x4008b490);
// unless you have MY on the receiving radio set to FFFF, this will be received as a RX16 packet
//Tx64Request tx = Tx64Request(addr64, payload, sizeof(payload));
TxStatusResponse txStatus = TxStatusResponse();
int pin5 = 0;
int statusLed = 11;
int errorLed = 12;
void flashLed(int pin, int times, int wait) {
for (int i = 0; i < times; i++) {
digitalWrite(pin, HIGH);
delay(wait);
digitalWrite(pin, LOW);
if (i + 1 < times) {
delay(wait);
}
}
}
void setup() {
pinMode(statusLed, OUTPUT);
pinMode(errorLed, OUTPUT);
Serial1.begin(9600);
xbee.setSerial(Serial1);
}
void loop() {
// start transmitting after a startup delay. Note: this will rollover to 0 eventually so not best way to handle
if (millis() - start > 15000) {
// break down 10-bit reading into two bytes and place in payload
pin5 = analogRead(5);
payload[0] = pin5 >> 8 & 0xff;
payload[1] = pin5 & 0xff;
xbee.send(tx);
// flash TX indicator
flashLed(statusLed, 1, 100);
}
// after sending a tx request, we expect a status response
// wait up to 5 seconds for the status response
if (xbee.readPacket(5000)) {
// got a response!
// should be a znet tx status
if (xbee.getResponse().getApiId() == TX_STATUS_RESPONSE) {
xbee.getResponse().getTxStatusResponse(txStatus);
// get the delivery status, the fifth byte
if (txStatus.getStatus() == SUCCESS) {
// success. time to celebrate
flashLed(statusLed, 5, 50);
} else {
// the remote XBee did not receive our packet. is it powered on?
flashLed(errorLed, 3, 500);
}
}
} else if (xbee.getResponse().isError()) {
//nss.print("Error reading packet. Error code: ");
//nss.println(xbee.getResponse().getErrorCode());
// or flash error led
} else {
// local XBee did not provide a timely TX Status Response. Radio is not configured properly or connected
flashLed(errorLed, 2, 50);
}
delay(1000);
}
(J'ai fait attention d'ajouter un 1 au Seiral afin de convenir à l'arduino Leonardo.
Du côté récepteur on a:
#include <XBee.h>
/*
This example is for Series 1 XBee (802.15.4)
Receives either a RX16 or RX64 packet and sets a PWM value based on packet data.
Error led is flashed if an unexpected packet is received
*/
XBee xbee = XBee();
XBeeResponse response = XBeeResponse();
// create reusable response objects for responses we expect to handle
Rx16Response rx16 = Rx16Response();
Rx64Response rx64 = Rx64Response();
int statusLed = 11;
int errorLed = 12;
int dataLed = 10;
uint8_t option = 0;
uint8_t data = 0;
void flashLed(int pin, int times, int wait) {
for (int i = 0; i < times; i++) {
digitalWrite(pin, HIGH);
delay(wait);
digitalWrite(pin, LOW);
if (i + 1 < times) {
delay(wait);
}
}
}
void setup() {
pinMode(statusLed, OUTPUT);
pinMode(errorLed, OUTPUT);
pinMode(dataLed, OUTPUT);
// start serial
Serial.begin(9600);
xbee.setSerial(Serial);
flashLed(statusLed, 3, 50);
}
// continuously reads packets, looking for RX16 or RX64
void loop() {
xbee.readPacket();
if (xbee.getResponse().isAvailable()) {
// got something
if (xbee.getResponse().getApiId() == RX_16_RESPONSE || xbee.getResponse().getApiId() == RX_64_RESPONSE) {
// got a rx packet
if (xbee.getResponse().getApiId() == RX_16_RESPONSE) {
xbee.getResponse().getRx16Response(rx16);
option = rx16.getOption();
data = rx16.getData(0);
} else {
xbee.getResponse().getRx64Response(rx64);
option = rx64.getOption();
data = rx64.getData(0);
}
// TODO check option, rssi bytes
flashLed(statusLed, 1, 10);
// set dataLed PWM to value of the first byte in the data
analogWrite(dataLed, data);
} else {
// not something we were expecting
flashLed(errorLed, 1, 25);
}
} else if (xbee.getResponse().isError()) {
//nss.print("Error reading packet. Error code: ");
//nss.println(xbee.getResponse().getErrorCode());
// or flash error led
}
}
C'est simplement les programmes de test que j'ai peu modifié. Help please!!
