    Exploring raspberry pi serial port Exploring raspberry pi serial port Presentation Transcript

    • Exploring Raspberry Pi’s Serial Port Sudar (@sudarmuthu) http://hardwarefun.com https://github.com/sudar
    • I am going to assume • You know what is Raspberry Pi • You know what is Arduino • You know what is a serial Port
    • Raspberry Pi has a serial Port
    • Using Raspberry Pi’s Serial Port • To login via serial console • To communicate with other devices like Arduino
    • Raspberry Pi’s pins or only 3.3V compatible. Don’t connect 5V directly You will brick your Raspberry Pi
    • Using Serial port to log into RPi • • • • You need a USB-to-serial adapter If not 3.3V then you need a logic level convertor Connect Tx of RPi to Tx of adapter and Rx to Rx Power up RPi and you can login using the serial console. • If you don’t have a USB-to-Serial adapter, then you can use Arduino http://hardwarefun.com/tutorials/using-arduinoas-a-bridge-to-connect-serial-devices-with-pc
    • Using RPi’s Serial Port to communicate with devices • By default this is disabled. • You need to enable it. Usehttps://github.com/lurch/rpi-serial-console • Connect Rx of RPi to Tx of your device (Arduino) and Tx of RPi to Rx of your device • Use a simple serial echo program https://github.com/sudar/arduino-roboticsworkshop/tree/master/Serial/two_arduino_serial • You can use screen in Rpi • Profit 
    • Thank You
