How to control GPIO?

Parts. For this tutorial,you don’t need many parts. A computer to put the app on the phone.

  • The App. For the app,you can use the app from this tutorial I made.
  • Raspberry Pi. On the raspberry pi,you should install 2 things. Wiring pi is used to control the GPIO pins from the php page.
  • Resume. I hope you liked it.
  • What is the use of GPIO on Embedded Board?

    GPIO is your standard pins that can be used to turn devices on and off. I2C ( Inter-Integrated Circuit) pins allow you to connect and talk to hardware modules that support this protocol (I2C Protocol). SPI ( Serial Peripheral Interface Bus) pins can be used to connect and talk to SPI devices.

    What is meant by GPIO driver?

    A GPIO controller driver is a KMDF driver that manages all hardware-specific operations for a GPIO controller . The GPIO controller driver cooperates with GpioClx to handle I/O requests for groups of GPIO pins that are configured as data inputs and data outputs.

    What is a GPIO device?

    A GPIO device is a device that performs actions based upon triggers sent by the RFID reader, providing additional functionality like audio or visual signals. Most fixed RFID readers have GPIO ports that allocate certain voltage levels to input and output electric signals.
