r_ioport Module Guide Resources

Last Updated:02/27/2018


Where can I find the references to module guide resources for the IO Port HAL module on r_ioport?


Information on the module guide itself and the associated resources and known issues are available here.


The I/O Port HAL module is a high-level API for controlling I/O pins and is implemented on r_ioport. The I/O Port HAL module configures the board’s pins and provides functions for manipulating them. The operating state of the I/O pins can be set via the Synergy configurator. When the Synergy project is built, a pin configuration file is created, and when the application runs, the BSP will configure the IO port accordingly, using the same APIs detailed in this document.

This module configures one or more I/O pins. The direction of the pin or pins can be configured along with a number of other options provided as follows:

  • Pull-up
  • Drive strength
  • Event edge trigger (falling, rising or both)
  • Whether the pin is to be used as an IRQ pin
  • Whether the pin is to be used as an analog pin
  • Whether the pin is to be used as a peripheral pin and which peripheral


The module also provides the following functionality:

  • Changes the direction of one or more pins on a port
  • Writes to one or more pins on a port
  • Reads from one or more pins on a port
  • Sets event output data
  • Reads event input data
