Bonsoir, j'ai ici un programme pour le RFID READER pour lire des badges à l'entrée d'un portail
Mon programme c'est :
/*
link between the computer and the SoftSerial Shield
at 9600 bps 8-N-1
Computer is connected to Hardware UART
SoftSerial Shield is connected to the Software UART:D2&D3
*/
#include <SoftwareSerial.h>
SoftwareSerial SoftSerial(2, 3);
unsigned char buffer[64]; // buffer array for data receive over serial port
int count = 0; // counter for buffer array
void setup()
{
SoftSerial.begin(9600); // the SoftSerial baud rate
Serial.begin(9600); // the Serial port of Arduino baud rate.
}
void loop()
{
// if date is coming from software serial port ==> data is coming from SoftSerial shield
if (SoftSerial.available())
{
while(SoftSerial.available()) // reading data into char array
{
buffer[count++] = SoftSerial.read(); // writing data into array
if(count == 64)break;
}
Serial.write(buffer, count); // if no data transmission ends, write buffer to hardware serial port
clearBufferArray(); // call clearBufferArray function to clear the stored data from the array
count = 0; // set counter of while loop to zero
}
if (Serial.available()) // if data is available on hardware serial port ==> data is coming from PC or notebook
SoftSerial.write(Serial.read()); // write it to the SoftSerial shield
}
void clearBufferArray() // function to clear buffer array
{
// clear all index of array with command NULL
for (int i=0; i<count; i++)
{
buffer[i]=NULL;
}
}
J'aimerai donc savoir si c'est possible de recevoir des signaux comme : Madame X , Y , Z
Car c'est pour identifié la personne à l'aide de son badge.
Merci d'avance
