今天拿到了新板子 -- ESM32-CAM
順勢測試一下ESP-IDF開發環境以及這塊板子Camera的效能

以下參考資料都來自 Ai-Thinker提供的 ESP32_CAMERA_QR 使用教程
https://github.com/donny681/ESP32_CAMERA_QR/wiki

Step 1: 首先, 照 ESP32_CAMERA_QR 使用教程連接 USBtoTTL, 注意喔! 這塊板子的工作電壓是5V,不是3.3V !

Step 2: 接著就下載原始碼
git clone https://github.com/donny681/ESP32_CAMERA_QR.git

Step 3: 再來當然就是 make flash (build code 以及 download code, 一指令搞定)

Step 4: 接著就是透過 make monitor 來觀察 camera 運作狀況了

Conclusion:
1. 初試結果,感覺效能不好 (官網資料就不是很好啊,自己要買還嫌)

2. 範例程式穩定度很差,stream mode 常跑不到100 frames 就hang住了


rst:0x1 (POWERON_RESET),boot:0x12 (SPI_FAST_FLASH_BOOT)

掛了! :-( :-( :-(

3. 再來就是身為工程師的你來改進它吧!

The Windows 10 build 14393 or later version is ready to Linux installation by using the Windows Subsystem.

By this way you don't need to setup a virtual machine or reboot into Linux by using a dual-boot PC.
