X Shifterのスイッチユニットを自作しました。Ver2.0-AE-TYBLE16開発環境の構築-はじめに
https://chikuwa-ringyo.com/?p=529
前回使用するモジュールを決めたので、このモジュール...
↓みたいな感じになります。
参考動画
使ったもの
・AE-TYBLE16
秋月電子で購入
・電池ケース
秋月電子で購入
・タクトスイッチ
秋月電子で購入
・ケーブル
モノタロウで購入
回路図
スイッチと電池つなぐだけです。
ソースコード
nRF5_SDK_12.3のble_app_hrs_cをベースプロジェクトとして修正しました。
修正したファイルは以下の3つ。（クロックの設定などは前回の記事で変更していること前提)
・main.c
・sdk_config.h(ble_app_hrs_c\pca10028\s130\config内)
・pca10028.h(components\boards内)
修正してビルドして、作成したhexファイルをSoftDeviceS130のHexと一緒に書き込んでおしまいです。
sdk_config.h
以下の箇所を変更
706行目
#define GPIOTE_CONFIG_IRQ_PRIORITY 3
=> #define GPIOTE_CONFIG_IRQ_PRIORITY 1
2708行目
#define UART_ENABLED 1
=> #define UART_ENABLED 0
2782行目
#define UART0_ENABLED 1

#define BUTTON_1 17
#define BUTTON_2 18
#define BUTTON_3 19
=>
#define BUTTON_1 18
#define BUTTON_2 17
#define BUTTON_3 5
にする。
