Enable UART

Execute the following command to enter the Raspberry Pi configuration:

sudo raspi-config

Choose Interfacing Options -> Serial -> No -> Yes:
You need to disable the login shell and enable the srial port hardware:

Reboot Raspberry Pi:

sudo reboot

Open the /boot/config.txt file and find the following configuration statement to enable the serial port, if not, add it at the end of the file:

enable_uart=1

Reboot to take effect.

Enable I2C Interface

Open a terminal and run the following commands:

sudo raspi-config 
Choose Interfacing Options -> I2C -> Yes.

Reboot Raspberry Pi:

sudo reboot

Install libraries

Open a terminal and run the following commands to install libraries

sudo apt-get install update
sudo apt-get install python3-serial
sudo pip install smbus

Configure the Module

• Connect the Sensor board to Windows PC and set the UART baud rate to 921600
• Connect the sensor to Raspberry Pi

• 

  Connect to Raspberry Pi-I2C

• 

  Connect to Raspberry Pi-UART

• Download the example and unzip

cd 
wget https://www.waveshare.com/w/upload/0/01/TOF-Laser-Range-Sensor-B-Demo.zip
