So what do you think should I change the connection pins or change a specific registery in your library
That is the test code so what do you think ?
```
Code: Select all
#include <Adafruit_NeoPixel.h>
#include <Wire.h>
#include <VL6180X_WE.h>
#define VL6180X_ADDRESS 0x29
#define LED 2
#define LEDNR 16
#define TOF_INT 12
#define SCL_PIN 5
#define SDA_PIN 4
VL6180xIdentification identification;
VL6180x TOFsensor(VL6180X_ADDRESS);
Adafruit_NeoPixel pixels(LEDNR, LED, NEO_GRB + NEO_KHZ800);
int i = 0;
volatile bool interruptReceived = false;
ICACHE_RAM_ATTR void handleInterrupt() {
interruptReceived = true;
}
void setup() {
Serial.begin(115200);
Wire.begin(SDA_PIN, SCL_PIN); //Initialize I2C for VL6180x (TOF Sensor)
pixels.begin(); // Initialize NeoPixel ring
pixels.clear();
pixels.show();
pinMode(TOF_INT, INPUT_PULLUP);
attachInterrupt(digitalPinToInterrupt(TOF_INT), handleInterrupt, FALLING);
delay(1000);
while(TOFsensor.VL6180xInit() == VL6180x_FAILURE_RESET){
Serial.println("FAILED TO INITALIZE"); //Initialize device and check for errors
}
TOFsensor.VL6180xDefautSettings(); //Load default settings to get started.
delay(1000);
TOFsensor.VL6180xSetDistInt(10 ,10);
TOFsensor.getDistanceContinously();
}
void loop() {
if (interruptReceived) {
Serial.println("Intrerupt received");
Serial.println(TOFsensor.getLastDistanceFromHistory());
for (int i = 0; i < LEDNR; i++) {
pixels.setPixelColor(i, pixels.Color(50, 0, 0));
pixels.show();
delay(100);
}
Serial.println("Light Set");
interruptReceived = false;
TOFsensor.VL6180xClearInterrupt();
Serial.println("Intrerupt cleared");
}
pixels.clear();
pixels.show();
}
```Note:(from VL6180X_WE.h library I get the function names and specific parts that contian getregister and setregister values so you can have a look at the register values so maybe you can suggest I can modify the register value so the intteruption function can work properly
