13' LCD 디스플레이어

왼쪽위 - 디스플레이어 보드, 가운데 - 라즈베리파이4, 오른쪽아래 - USB 충전기, DC/DC 아답터

개요

스위치를 이용하여 BootSelect 하기위해 기본적인 python을 이용한 print 시험

구성

소스코드

#i /user/bin/python

from gpiozero import Button
import subprocess

if Button(2).is_pressed & Button(4).is_pressed:
        print('Gpio_2 & Gpio_4')

elif (not Button(2).is_pressed) & Button(4).is_pressed:
        print('Gpio_4')

elif (not Button(4).is_pressed) & Button(2).is_pressed:
        print('Gpio_2')

else:
        print('Not Input')

결과

목적 : 이동식 Mame게임기 및 Kodi 미디어 플레어 만들기

준비 (국내 온라인 사이트에서 구할수가 없어서 AliExpress에서 구매 진행) (약 $1 = \1,200)

1) Raspberry Pi4 - 4Gb $ 65.52 X1

https://ko.aliexpress.com/item/4000054868537.html?spm=a2g0s.9042311.0.0.683d4c4d07fy7P

2) Raspberry Pi4 방열 케이스 $ 15.19 X1

https://ko.aliexpress.com/item/4000061381216.html?spm=a2g0s.9042311.0.0.683d4c4d07fy7P

3) 게임패드 $ 26.38 X2

https://ko.aliexpress.com/item/32840716891.html?spm=a2g0s.9042311.0.0.683d4c4d07fy7P

4) 13'3인치 Display 모듈 $ 49.40 X1

https://ko.aliexpress.com/item/4000112143939.html?spm=a2g0s.9042311.0.0.683d4c4d07fy7P

5) 기타 : 충전기 5V/3A, USB-C Type Cable, micro HDMI Cable 약\20,000원

6) 아크릴 케이스 : 예상비용 : 3만3천7백원 - 기본적인 설계는 완료했으나. Display 모듈 입고 후 확인하고 제작 예정

https://www.acryiae.com/front/mypage/orderList.do

총 금액 $156.49 + 2만 + 3만3천7백‬ = \241,488‬원

많이도 들어갔내...

진행상황

Mame 적용완료,

Mame 2000, 2003, 2010 게임 실행 완료

Kodi 한글화 적용완료,

앞으로 진행

전원 인가시 스위치모드에 따라서 RetroPi 부팅, Kodi 부팅, Raspbian 부팅 설정예정 - 완료
스위치 자동 실행시 RetroPi 게임 실행 안되는 문제 있음.
