I have a question about my code. It is a program which should send my car number through an nrf24l01 transceiver once an IR receiver receives a signal.
So in short IR beam is received send number.
It consists of a track program delivered by the school and the car part is my excercise, and I'm wondering if my code is correct. It is for an arduino DUE board
Track code:
[CODE title="Track code for refference"]
#include <IRremote2.h>
#include <SPI.h>
#include <nRF24L01.h>
#include <RF24.h>
IRsend BeamIR; //Initialize IR transmitter object
RF24 TrackRadio(4, 6); //Radio pins (CE, CSN)
const int IRQpin = 5; //Radio interrupt pin
const int resetPin = 2; //Arduino reset pin
const byte address[6] = "5XIA0"; //Radio Address: Set to the Energy Challenge course code
unsigned long IRtime = 0; //Variable to time infrared pulses
volatile boolean CarPassed = false; //Boolean to indicate a car has passed
byte CarNumber = 0; //Variable to temporarily store the received car number
unsigned long carTime[256]; //Data array to store lap times
int time2print; //Variable to temporarily store time to be sent to the GUI
void setup()
{
for (int i = 0; i <= 255; i++) //Initialize whole carTime array
{
carTime = -10000; //Set to -10000 to make sure the system immediately works without delay
}
Serial.begin(9600); //Initialize Serial communication
digitalWrite(resetPin, HIGH); //Set the reset pin to high
delay(20);
attachInterrupt(IRQpin, Radio, FALLING); //Trigger the "radio" function when the radio interrupt pin goes low
pinMode(resetPin, OUTPUT); //Set reset pin as output
TrackRadio.begin(); //Start radio object
TrackRadio.openReadingPipe(0, address); //Open communication pipe at defined address
TrackRadio.setPALevel(RF24_PA_LOW); //Set power level of radio
TrackRadio.startListening(); //Tell the radio to start receiving
TrackRadio.maskIRQ(1,1,0); //Mask IRQ pin so the interrupt is only triggered when it receives data
pinMode(13, OUTPUT);
digitalWrite(13, HIGH);
delay(3000);
digitalWrite(13, LOW);
}
void loop()
{
if (millis() - IRtime >= 25) //Send IR pulse every 25ms
{
IRtime = millis(); //Save current time
BeamIR.sendSony(1, 2); //Send the number 1 with a length of two bits(01) through the Sony protocol
}
if (CarPassed) //If a car has passed, execute loop
{
CarPassed = false; //Set Boolean back to false
if (TrackRadio.available()) //If data is available at the radio, execute loop
{
TrackRadio.read(&CarNumber, sizeof(CarNumber)); //Read the received car number from the radio
}
if (millis() - carTime[CarNumber] > 10000) //When the previous received ID is more then 10 seconds ago, execute loop
{
time2print = millis() - carTime[CarNumber]; //Calculate lap time
Serial.println(CarNumber); //Print car number to serial(send to matlab GUI)
Serial.println(time2print); //Print lap time to serial(send to matlab GUI)
carTime[CarNumber] = millis(); //Save current time
}
}
if (Serial.available()) //If data is received at the serial port, execute loop
{
char recChar = Serial.read(); //Read data from Serial port
if (recChar == 'r') //If received data is equal to "r", execute loop
{
digitalWrite(resetPin, LOW); //Set reset pin to LOW to reset Arduino
}
}
}
//When data is received at the radio, the function is executed
//CarPassed is set to true to indicate a car has passed the finish
void Radio()
{
CarPassed = true;
