121-128 | NC | No-connect pins. Leave unconnected. |
While the RTD2660H is not directly compatible with Arduino UNO due to its complexity, the I2C interface can be used for basic communication. Below is an example Arduino sketch to configure the RTD2660H via I2C:
#include <Wire.h> // Include the Wire library for I2C communication
#define RTD2660H_I2C_ADDRESS 0x50 // Default I2C address of RTD2660H
void setup() {
Wire.begin(); // Initialize I2C communication
Serial.begin(9600); // Initialize serial communication for debugging
// Send a configuration command to RTD2660H
Wire.beginTransmission(RTD2660H_I2C_ADDRESS);
Wire.write(0x01); // Example register address
Wire.write(0x80); // Example data to configure the IC
Wire.endTransmission();
Serial.println("RTD2660H configured successfully.");
}
void loop() {
// Add code here to read or write additional data if needed
}
