mruby-esp32-gpio

GPIO library for mruby-esp32.

Installation

In esp32_build_config.rb, at the end of the MRuby::CrossBuild block, add the following:

  conf.gem :github => 'mruby-esp32/mruby-esp32-gpio'

In CMakeLists.txt, make sure the line PRIV_REQUIRES includes the driver component. Add it if needed:

  add_prebuilt_library(
    libmruby ${LIBMRUBY_FILE}
    PRIV_REQUIRES esp_wifi esp_hw_support esp_rom mqtt driver 
  )

Example

include ESP32::Constants
include ESP32::GPIO

led = GPIO_NUM_4
pinMode(led, OUTPUT)

loop {
  digitalWrite(led, HIGH)
  ESP32::System.delay(1000)
  digitalWrite(led, LOW)
  ESP32::System.delay(1000)
}

Note: To use include syntax on top level objects, mruby-toplevel-ext mrbgem is required.
