bonjour, qui peux m'aider il y a une probleme dans mon code recepteur le but est pour lire deux valeurs analogique avec RF 433mhz et la librarie virtual wire
#include <VirtualWire.h>
int ledPin = 13;
int Sensor1Data;
int Sensor2Data;
// RF Transmission container
char Sensor1CharMsg[4];
char Sensor2CharMsg[4];
void setup() {
Serial.begin(115200);
// sets the digital pin as output
pinMode(ledPin, OUTPUT);
vw_set_ptt_inverted(true);
vw_set_rx_pin(12);
// Bits per sec
vw_setup(2000);
// Start the receiver PLL running
vw_rx_start();
} // END void setup
void loop(){
uint8_t buf[VW_MAX_MESSAGE_LEN];
uint8_t buflen = VW_MAX_MESSAGE_LEN;
// Non-blocking
if (vw_get_message(buf, &buflen))
{
int i;
// Turn on a light to show received good message
digitalWrite(13, true);
// Message with a good checksum received, dump it.
for (i = 0; i < buflen; i++)
{
// Fill Sensor1CharMsg Char array with corresponding
// chars from buffer.
Sensor1CharMsg[i] = char(buf[i]);
}
Sensor1CharMsg[buflen] = '\0';
float Sensor1Data = atoi(Sensor1CharMsg)*(5.0/ 1023.0);
Serial.print(Sensor1Data);
// Null terminate the char array
// This needs to be done otherwise problems will occur
// when the incoming messages has less digits than the
// one before.
// Convert Sensor1CharMsg Char array to integer
// DEBUG
// END DEBUG
// Turn off light to and await next message
digitalWrite(13, false);
}
}
le code transmetteur je croie vraie
#include <VirtualWire.h>
int ledPin = 13;
int Sensor1Pin = A2;
int Sensor2Pin = A3;
int Sensor1Data;
char Sensor1CharMsg[4];
int Sensor2Data;
char Sensor2CharMsg[4];
void setup() {
pinMode(Sensor1Pin,INPUT);
pinMode(Sensor2Pin,INPUT);
vw_set_tx_pin(12);
vw_set_ptt_inverted(true);
vw_setup(2000); // Bits per sec
pinMode(ledPin,OUTPUT);
}
void loop() {
// Read and store Sensor 1 data
Sensor1Data = analogRead(Sensor1Pin);
// Convert integer data to Char array directly
itoa(Sensor1Data,Sensor1CharMsg,10);
Serial.print(Sensor1Data);
Serial.println(Sensor1CharMsg);
delay(10);
digitalWrite(13, true); // Turn on a light to show transmitting
vw_send((uint8_t *)Sensor1CharMsg, strlen(Sensor1CharMsg));
vw_wait_tx(); // Wait until the whole message is gone
// Turn off a light after transmission
delay(30);
Sensor2Data = analogRead(Sensor2Pin);
// Convert integer data to Char array directly
itoa(Sensor2Data,Sensor2CharMsg,10);
Serial.print(Sensor2Data);
Serial.println(Sensor2CharMsg);
delay(10);
//
digitalWrite(13, true); // Turn on a light to show transmitting
vw_send((uint8_t *)Sensor2CharMsg, strlen(Sensor2CharMsg));
vw_wait_tx(); // Wait until the whole message is gone
// Turn off a light after transmission
delay(30);
} // END void loop...
