Guardian Sentinel - The Slave

<Part 4>

For the slave, i decided to use the similar setup, hence i decide to use the FeatherWing Tripler Mini Kit.

The following image shows the header pins being soldered

Once finish soldering, I place the MAX32630FTHR in the middle.

Followed by the FTHR-PMD-INTZ Feather-to-PMOD

Which is place to the right of the MAX32630FTHR

For further info on the FTHR-PMD-INTZ Feather-to-PMOD click here. Following that, i place the DC Motor + Stepper FeatherWing Addon.

Which is place to left of the MAX32630FTHR

To ensure all the three boards are connected, i did the i2C scanner and below are the result

#include <Wire.h>

void setup() {
  Serial.begin(115200);
  while (!Serial);

  Serial.println("MAX32630FTHR I2C Scanner");
  Wire.begin();
}

void loop() {
  byte error, address;
  int devices = 0;

  Serial.println("Scanning I2C bus...");

  for (address = 1; address < 127; address++) {
    Wire.beginTransmission(address);
    error = Wire.endTransmission();

    if (error == 0) {
      Serial.print("I2C device found at address 0x");
      if (address < 16) Serial.print("0");
      Serial.println(address, HEX);
      devices++;
    }
  }

  if (devices == 0) {
    Serial.println("No I2C devices found.");
  } else {
    Serial.print("Total devices found: ");
    Serial.println(devices);
  }

  Serial.println();
  delay(3000);
}

and the result from the serial monitor is shown below
