【2022年最新版】Timer Camera Fで定点カメラを作ってLINEに通知

· 約11分
moritalous

1年前に書いたTimer Camera Fで定点カメラを作ってLINEに通知が2022/8/11時点でうまく動かないことがわかりました。修正箇所を記載します。

最小構成でビルド​

まずは、以下の構成

  • platformio.ini
[env:m5stack-timer-cam]
platform = espressif32
board = m5stack-timer-cam
framework = arduino
lib_deps = 
    m5stack/Timer-CAM
upload_speed = 1500000
monitor_speed = 115200
  • main.cpp
#include <Arduino.h>
#include <WiFi.h>

#include "battery.h"
#include "led.h"
#include "bmm8563.h"

#include "esp_camera.h"
#include "camera_pins.h"

void setup()
{

}

void loop()
{

}

結果​

ビルド失敗

Timer-CAMライブラリーをGitから最新版を取得​

PlatformIOではGitリポジトリを指定してライブラリーを取得することが可能です。

platformio.ini
[env:m5stack-timer-cam]
platform = espressif32
board = m5stack-timer-cam
framework = arduino
lib_deps = 
    ; m5stack/Timer-CAM
    https://github.com/m5stack/TimerCam-arduino.git
upload_speed = 1500000
monitor_speed = 115200
注記

GitHubのリポジトリを直接指定できます。

LINE Notifyトークンの発行​

久しぶりにやるとやり方がわからなくなったので備忘録

  1. https://notify-bot.line.me/login にアクセス
  2. ログイン
  3. マイページ( https://notify-bot.line.me/my/ )へ遷移
  4. アクセストークンの発行(開発者向け) からトークンを発行
注記

LINE Notify便利です。

実行結果​

成功しました。

それにしても暑い😫
