Nordic Nrf528xx를 사용해 보자 nrf52840 Uno Arduino 편 2 Arduino에 커스텀 보드를 등록하자

Nordic Nrf528xx를 사용해 보자 nrf52840 Uno Arduino편(MDBT50Q)의 계속입니다.
htps : // 코 m / 우사시로 / ms / 아 060 아 116f1f280bf8451

이번에는 nrf52840 MDBT50Q를 탑재한 Arduino Uno용 보드 데이터를 작성해 봅시다.
(nrf52840DK와 기본은 동일하므로, DK보드를 가지고 있는 분은, 아래의 프로파일을 작성하면, 4버튼, 4LED를 사용 가능합니다)

boards.txt 설명 추가

하드웨어 파일 추가
합니다.

본 기술 내용은 Github에서 다운로드 가능합니다.

그럼 네 개의 LED를 깜박입니다.

4Blink

/*
  Blink

  Turns an LED on for one second, then off for one second, repeatedly.

  Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO
  it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to
  the correct LED pin independent of which board is used.
  If you want to know what pin the on-board LED is connected to on your Arduino
  model, check the Technical Specs of your board at:

Button to LED

버튼을 누르면 LED가 켜지는 프로그램

/*
  Button

  Turns on and off a light emitting diode(LED) connected to digital pin 13,
  when pressing a pushbutton attached to pin 2.

  The circuit:
  - LED attached from pin 13 to ground
  - pushbutton attached to pin 2 from +5V
  - 10K resistor attached to pin 2 from ground

  - Note: on most Arduinos there is already an LED on the board
    attached to pin 13.
