Can't read I2C addresses 0x70 and 0x68

[houssemFat]

Hello and thank you for the great work.

I recently purchased the esp rust board. As it is based on esp32 C3, i tried with some arduino sketches using arduino IDE and arduino-esp standard library. Codes are ok with RGB (WS2812), serial output and build in led (GPIO7) (using the LOLIN C3 mini as the board for arduino ide) .

I'm assuming that the board is arduino compatible (please correct me if i'm wrong).

Now, i'm trying to read values from the onboard sensors (SHTC3 and ICM-42670-P) using the given i2c addresses (0x68 & 0x70). I'm using a dummy I2C scanner, but it keeps getting error code 2.

I tried the many arduino library for SHTC3 (eg: Adafruit_SHTC3 with no luck.

Scanner code

#include <Wire.h>
void setup() {
  Wire.begin();
  Serial.begin(115200);
  Serial.println("\nI2C Scanner");
}
 
void loop() {
  byte error;
  delay(2000);     
  // replace with 0x70 for SHTC3
  // ICM-42670-P
  Wire.beginTransmission(0x68); 
  error = Wire.endTransmission();
  if (error == 0) {
    Serial.println("OK, Found");
  }else {
    Serial.println("NOT OK ");
     Serial.println(error);
  }
  delay(2000);          
}

Output

23:37:27.896 -> NOT OK 
23:37:27.896 -> 

Am I missing something ? Maybe using a wrong board definition ?
I appreciate any help !
