Bonjour,
Je dispose d'un ESP32 et d'un accéléromètre BNO055.
Je parviens à envoyer recueillir des données de mon accéléromètre grâce au code suivant
#include <Wire.h>
#include <Adafruit_Sensor.h>
#include <Adafruit_BNO055.h>
#include <utility/imumaths.h>
Adafruit_BNO055 bno = Adafruit_BNO055(55);
void setup(void)
{
Serial.begin(9600);
Serial.println("Orientation Sensor Test"); Serial.println("");
/* Initialise the sensor */
if(!bno.begin())
{
/* There was a problem detecting the BNO055 ... check your connections */
Serial.print("Ooops, no BNO055 detected ... Check your wiring or I2C ADDR!");
while(1);
}
delay(1000);
bno.setExtCrystalUse(true);
}
void loop(void)
{
/* Get a new sensor event */
sensors_event_t event;
bno.getEvent(&event);
// Possible vector values can be:
// - VECTOR_ACCELEROMETER - m/s^2
// - VECTOR_MAGNETOMETER - uT
// - VECTOR_GYROSCOPE - rad/s
// - VECTOR_EULER - degrees
// - VECTOR_LINEARACCEL - m/s^2
// - VECTOR_GRAVITY - m/s^2
imu::Vector<3> accel = bno.getVector(Adafruit_BNO055::VECTOR_LINEARACCEL);
Serial.print("X: ");
Serial.print(accel.x());
Serial.print(" Y: ");
Serial.print(accel.y());
Serial.print(" Z: ");
Serial.print(accel.z());
Serial.println("");
delay(100);
}
Je désire maintenant envoyer ces données à mon smartphone par Wifi grâce à l'application Blynk. Pour l'instant j'arrive à envoyer un entier prédéfini avec le code suivant :
#define BLYNK_PRINT Serial
#include <WiFi.h>
#include <WiFiClient.h>
#include <BlynkSimpleEsp32.h>
// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "cd0cc10a226a4efab744f98a055ef4f2";
// Your WiFi credentials.
// Set password to "" for open networks.
char ssid[] = "WifiG4";
char pass[] = "Wifitinou";
BlynkTimer timer;
// This function sends Arduino's up time every second to Virtual Pin (5).
// In the app, Widget's reading frequency should be set to PUSH. This means
// that you define how often to send data to Blynk App.
void myTimerEvent()
{
// You can send any value at any time.
// Please don't send more that 10 values per second.
Blynk.virtualWrite(V5, 30);
}
void setup()
{
// Debug console
Serial.begin(9600);
Blynk.begin(auth, ssid, pass);
// You can also specify server:
//Blynk.begin(auth, ssid, pass, "blynk-cloud.com", 80);
//Blynk.begin(auth, ssid, pass, IPAddress(192,168,1,100), 8080);
// Setup a function to be called every second
timer.setInterval(1000L, myTimerEvent);
}
void loop()
{
Blynk.run();
timer.run(); // Initiates BlynkTimer
}
J'ai donc essayé d'assembler ces deux codes afin d'envoyer les données du BNO, ce qui donne ça :
#define BLYNK_PRINT Serial
#include <Wire.h>
#include <Adafruit_Sensor.h>
#include <Adafruit_BNO055.h>
#include <utility/imumaths.h>
#include <WiFi.h>
#include <WiFiClient.h>
#include <BlynkSimpleEsp32.h>
// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "cd0cc10a226a4efab744f98a055ef4f2";
// Your WiFi credentials.
// Set password to "" for open networks.
char ssid[] = "WifiG4";
char pass[] = "Wifitinou";
Adafruit_BNO055 bno = Adafruit_BNO055(55);
BlynkTimer timer;
// This function sends Arduino's up time every second to Virtual Pin (5).
// In the app, Widget's reading frequency should be set to PUSH. This means
// that you define how often to send data to Blynk App.
void myTimerEvent()
{
// You can send any value at any time.
// Please don't send more that 10 values per second.
/* Get a new sensor event */
sensors_event_t event;
bno.getEvent(&event);
imu::Vector<3> accel = bno.getVector(Adafruit_BNO055::VECTOR_LINEARACCEL);
Blynk.virtualWrite(V5, "X: ", accel.x());
}
void setup()
{
// Debug console
Serial.begin(9600);
Blynk.begin(auth, ssid, pass);
// You can also specify server:
//Blynk.begin(auth, ssid, pass, "blynk-cloud.com", 80);
//Blynk.begin(auth, ssid, pass, IPAddress(192,168,1,100), 8080);
// Setup a function to be called every second
timer.setInterval(1000L, myTimerEvent);
}
void loop()
{
Blynk.run();
timer.run(); // Initiates BlynkTimer
}
Cependant, je reçois sur mon smartphone X : 0, ce qui n'est pas correct..
Pouvez-vous m'aider si vous voyez mon erreur svp ?
