Communication interface: UART (Serial) and I2CCode Examples### Example 1: Measuring AC Voltage using UART (Serial) Interface with ArduinoHardware Requirements:Digital Clamp Meter - DT-266
Arduino Board (e.g., Arduino Uno)
Serial cable (UART)Software Requirements:Arduino IDE (version 1.8.x or later)Code:
```c++
#include <SoftwareSerial.h>// Set up software serial for UART communication
SoftwareSerial dt266Serial(2, 3); // RX, TX pinsvoid setup() {
Serial.begin(9600);
dt266Serial.begin(9600);
}void loop() {
// Send command to measure AC voltage
dt266Serial.println("VAC");// Read response from DT-266
String response = dt266Serial.readStringUntil('
');// Extract measurement value
float voltage = response.toFloat();Serial.print("AC Voltage: ");
Serial.print(voltage);
Serial.println(" V");delay(1000);
}
```
Example Output:
```
AC Voltage: 120.5 V
AC Voltage: 120.5 V
AC Voltage: 120.5 V
...
```
### Example 2: Measuring DC Current using I2C Interface with Raspberry Pi (Python)Hardware Requirements:Digital Clamp Meter - DT-266
Raspberry Pi (e.g., Raspberry Pi 4)
I2C cableSoftware Requirements:Python 3.x
I2C library (e.g., `smbus`)Code:
```python
import smbus
import time# Set up I2C bus
bus = smbus.SMBus(1) # I2C bus number (1 for Raspberry Pi 4)# DT-266 I2C address
dt266_addr = 0x21# Send command to measure DC current
bus.write_i2c_block_data(dt266_addr, 0x01, [0x02]) # DCM (DC Current) command# Read response from DT-266
data = bus.read_i2c_block_data(dt266_addr, 0x02, 4) # Read 4 bytes (2 bytes for value + 2 bytes for CRC)# Extract measurement value
current = (data[0] << 8) + data[1]
current /= 100.0 # Convert to ampsprint("DC Current: {:.2f} A".format(current))time.sleep(1)
```
Example Output:
```
DC Current: 0.85 A
DC Current: 0.85 A
DC Current: 0.85 A
...
```
