  • The Service Interface provides a simple, clear, and flexible abstraction for accessing individual GPIO pins.[12]
  • In this article, we step through the declaration, implementation, and running of remote services for controlling individual GPIO Pins.[12]

  • These GPIOs can be controlled for digital input and output using the Python library provided in the Jetson GPIO Library package.[13]
  • GPIO is not added to the PYTHONPATH, the run_sample.sh script can be used to run these sample applications.[13]
  • This way, you can refer to the module as GPIO throughout the rest of the application.[13]
  • It is possible that the GPIO you are trying to use is already being used external to the current application.[13]
  • The Raspberry Pi offers up its GPIO over a standard male header on the board.[14]

  • The button is connected to Broadcom GPIO 17, aka P1 pin 11.[14]
  • GPIO module, and goes a step further by providing a local name -- GPIO -- which we'll call to reference the module from here on.[14]
  • Gert van Loo & Dom, have provided some tested code which accesses the GPIO pins through direct GPIO register manipulation in C-code.[15]

  • Raspberry Pi GPIO example using sysfs interface.[15]
  • (P1-07) while reading GPIO 24 (P1_18).[15]
  • Note: By default, "GPIO" allows any pin to be used interchangeably in read and write mode.[16]
  • By default , "GPIO" allows any pin to be used interchangeably in read and write mode.[16]
  • A GPIO (general-purpose input/output) port handles both incoming and outgoing digital signals.[17]
  • The GPIO is referred to as "general purpose" because each pin can be freely set to function as either an input or an output.[17]
  • The GPIO handles the necessary conversions in both directions.[17]
  • Sets the direction of each GPIO pin; either input or output.[17]
  • GPIO, or General-Purpose Input/Output, is a feature of most modern embedded computer hardware and a key component of many embedded systems.[18]
  • A GPIO is a signal pin on an integrated circuit or board that can be used to perform digital input or output functions.[18]
  • GPIO pins are digital, meaning they only support high/low or on/off levels.[18]
  • Some GPIO pins may directly support standardized communication protocols like serial communication, SPI, I2C, PCM, and PWM.[18]
  • You can configure GPIO pins as an input or output with either a high or low state.[19]
  • Note: To avoid damage to the GPIO pins, review the input and output limits of your hardware before making wire connections.[19]
  • A GPIO port is a platform-defined grouping of GPIO pins (often 4 or more pins).[20]
  • Example 7-1 Using the GPIO APIs import com.oracle.deviceaccess.[20]
