Using with Raspberry Pi

To use this mdoule, we provide python exmples for testing the PCA9685 as well as wifi remotel controlling and bluetooth controlling codes

Enable I2C Interface

Open a terminal and run the following commands:

sudo raspi-config 
Choose Interfacing Options -> I2C ->yes 

RPI open i2c.png
Reboot Raspberry Pi:

sudo reboot

Install libraries

sudo apt-get updata
sudo apt-get install python-pip 
sudo pip install RPi.GPIO
sudo apt-get install python-smbus

Downalod the demo codes and unzip

You should start the Raspberry Pi, open a terminal and run the following commands:

sudo apt-get install p7zip-full
wget http://www.waveshare.net/w/upload/6/6c/Servo_Driver_HAT.7z
7zr x Servo_Driver_HAT.7z -r -o./Servo_Driver_HAT
sudo chmod 777 -R Servo_Driver_HAT
cd Servo_Driver_HAT/Raspberry\ Pi/

Run The Examples

Python Examples

Open a terminal and runt the following comamnds:

#For python2
cd ~/Servo_Driver_HAT/Raspberry\ Pi/
cd python/
sudo python PCA9685.py
#For python3
cd ~/Servo_Driver_HAT/Raspberry\ Pi/
cd python3/
sudo python3 PCA9685.py

Expected result:Connect a servo to Channel 0, the servo will rotate.。

WIFI Remote Control

Open a terminal and run the following commands:

cd ~/Servo_Driver_HAT/Raspberry\ Pi/
cd Wifi-Control/
sudo python main.py

Expected result: Connect the Raspberry Pi and telephone to the same WLAN network. Data will be tranmsitted by TCP protocol. After running, the IP address and the Port are printed in terminal..

Open the APP and choose the WIFI control, input the IP address and the port then connect..
