Blynk and TOF10120 time of flight sensor

Projects made with Blynk

Hello, I just wanted to share this sketch with someone who needs it. It is for the tof10120 time of flight sensor to work with blynk. have fun with it.

#define BLYNK_PRINT Serial
#include <WiFi.h>
#include <WiFiClient.h>
#include <BlynkSimpleEsp32.h>
#include <Wire.h>

char auth[] = "";
char ssid[] = "";
char pass[] = "";
BlynkTimer timer;

 void myTimerEvent()
{

Blynk.virtualWrite(V6, millis() / 1000);
}

unsigned char ok_flag;
unsigned char fail_flag;

unsigned short lenth_val = 0;
unsigned char i2c_rx_buf[16];
unsigned char dirsend_flag=0;

void mydistanceEvent()
{
  

   int x=ReadDistance();
   Serial.print(x);
   Serial.println(" mm");
  Blynk.virtualWrite(V7, x);
 Blynk.virtualWrite(V8, x);
}

int serial_putc( char c, struct __file * )
{
  Serial.write( c );
  return c;
}

void printf_begin(void)
{

}



void SensorRead(unsigned char addr,unsigned char* datbuf,unsigned char cnt) 
{
  unsigned short result=0;
  // step 1: instruct sensor to read echoes
  Wire.beginTransmission(82); // transmit to device #82 (0x52)
  // the address specified in the datasheet is 164 (0xa4)
  // but i2c adressing uses the high 7 bits so it's 82
  Wire.write(byte(addr));      // sets distance data address (addr)
  Wire.endTransmission();      // stop transmitting
  // step 2: wait for readings to happen
  delay(1);                   // datasheet suggests at least 30uS
  // step 3: request reading from sensor
  Wire.requestFrom(82, cnt);    // request cnt bytes from slave device #82 (0x52)
  // step 5: receive reading from sensor
  if (cnt <= Wire.available()) { // if two bytes were received
    *datbuf++ = Wire.read();  // receive high byte (overwrites previous reading)
    *datbuf++ = Wire.read(); // receive low byte as lower 8 bits
  }
}

int ReadDistance(){
    SensorRead(0x00,i2c_rx_buf,2);
    lenth_val=i2c_rx_buf[0];
    lenth_val=lenth_val<<8;
    lenth_val|=i2c_rx_buf[1];
    delay(300); 
    return lenth_val;
}


void setup() 
{
  Wire.begin(); 
  Serial.begin(9600,SERIAL_8N1); 
  printf_begin();          
 Blynk.begin(auth, ssid, pass);
 timer.setInterval(20000L, myTimerEvent);
timer.setInterval(2000L, mydistanceEvent);
  
}

void loop() {
Blynk.run();
timer.run();
}
