Code Examples
### Example 1: Arduino Controlled LED Strip
In this example, we will use an Arduino board to control the XL4015 module to drive an LED strip.
Hardware:
XL4015 module
Arduino board (e.g., Arduino Uno)
LED strip (compatible with constant current output)
Breadboard and jumper wires
Code:
```c
const int enablePin = 2; // Connect EN pin to digital pin 2 on Arduino
const int adjPin = A0; // Connect Iadj pin to analog pin A0 on Arduino
void setup() {
pinMode(enablePin, OUTPUT);
pinMode(adjPin, OUTPUT);
}
void loop() {
// Set output voltage to 10V
analogWrite(adjPin, 1023 (10.0 / 12.0));
digitalWrite(enablePin, HIGH); // Enable the module
// Set current to 2A
analogWrite(adjPin, 1023 (2.0 / 5.0));
delay(1000);
digitalWrite(enablePin, LOW); // Disable the module
delay(1000);
}
```
In this example, the Arduino board controls the XL4015 module's output voltage and current using the `analogWrite()` function. The `enablePin` is used to turn the module on and off.
### Example 2: Lithium Battery Charging with Raspberry Pi
In this example, we will use a Raspberry Pi to monitor and control the XL4015 module's lithium battery charging function.
Hardware:
XL4015 module
Raspberry Pi (e.g., Raspberry Pi 3)
Lithium battery (compatible with the module's charging function)
Breadboard and jumper wires
Code:
```python
import RPi.GPIO as GPIO
import time
# Set up GPIO pins
GPIO.setmode(GPIO.BCM)
EN_PIN = 17 # Connect EN pin to GPIO 17 on Raspberry Pi
BAT_PIN = 23 # Connect BAT+ pin to GPIO 23 on Raspberry Pi
GPIO.setup(EN_PIN, GPIO.OUT)
GPIO.setup(BAT_PIN, GPIO.OUT)
while True:
# Charge the battery
GPIO.output(EN_PIN, GPIO.HIGH)
GPIO.output(BAT_PIN, GPIO.HIGH)
time.sleep(1)
# Check the battery voltage
bat_voltage = read_battery_voltage() # Implement your own function to read battery voltage
if bat_voltage >= 4.2: # Stop charging when the battery is fully charged
GPIO.output(EN_PIN, GPIO.LOW)
break
# Monitor the charging process
print("Charging...")
time.sleep(1)
```
In this example, the Raspberry Pi uses the `RPi.GPIO` library to control the XL4015 module's charging function. The code monitors the battery voltage and stops charging when the battery is fully charged.
