1 前言

本章測試下air105+gc9306+GC032A拍照。

2 硬件

開發板：air105
camera：105附帶的camera模組——GC032A
lcd屏幕：gc9306x

官方的demo使用的時PA10作為拍照按鍵，由于我焊接排針朝上，蓋在面包板上，boot按鍵按不到，使用keyboord0/1作為拍照按鍵。

3 官方代碼

https://gitee.com/openLuat/LuatOS/blob/master/demo/camera/Air105/capture/main.lua
官方示例使用的屏幕是st7789，需要根據自己的情況選擇。

4 調整代碼

我將camera的初始化放在了一個lua文件中。
PS：如果使用的是105固件版本 v0005，則需要將示例中lcd_init的gc9306x改為gc9306，如果是更高的版本則不需要這樣修改。

main.lua

5 結果

圖像顯示正常。

6 小結

后續加上105的tf卡，將圖片存到tf卡中。
或者使用uart傳輸到電腦上。
