Installation
Python
Library Installation
Before running this board you have to install the required libraries for RFID HAT.
- For Python3, install these two libraries by running the below command on the terminal.
sudo apt-get install python-smbus sudo apt-get install i2c-tools
Board TEST
Required Hardware
- Raspberry Pi x 1
- RFID HAT x 1
Enable I2C and Serial Interface
- Open a terminal and run the following commands to enable I2C：
sudo raspi-config
Choose Interfacing Options -> I2C ->yes
- Again run below command to enable Serial
sudo raspi-config
Choose Interfacing Options -> Serial -> No -> Yes
- You can also enable Serial and I2C using Graphical method, Open Menu by clicking on Raspberry Pi icon >> Preferences >> Raspberry Pi Configurations >> Interfaces , and select below option.
- Now reboot your pi by running the below command :
sudo reboot
Testing
- Stack RFID-HAT on GPIO Header of Raspberry Pi.
- To run examples of SB-PI-HAT, clone this repository by executing below command
git clone https://github.com/sbcshop/SB-RFID-HAT.git cd SB-RFID-HAT
- Now run example code by running the below commands.
python3 rfid.py (Without Oled display, output on terminal/shell)
OR
python3 rfid_with_oled.py ( To show detected tag id on Oled as well as on terminal/shell)
