我把FR8016HA开发板的声音播放跑通了,
(1)烧录程序:不能用gitee最新版,要用旧资料的代码(会导致屏幕花屏,但功能正常)
(2)需要用特定的安卓手机才能正常蓝牙传输wav文件,我用的是红米4A,安卓6,
安卓是gitee上的SBC最新版
(3)我接的喇叭是8Ω0.5W圆形喇叭(8R),带公头杜邦线(需面包板),原版没有,需要自备
(4)按K1数次,然后按K2播放

和UI.bin合并成all.bin然后烧录到flash (用bin打包工具合并到0x200000)
然后可以只烧录ble_simple_peripheral.bin(写到0x0)

我终于跑通了富芮坤FR8008XP开发板和400分辨率圆形屏的用法,烧录效果如下。这里有几个问题
(1)如果直接烧录,图片会花屏,那是因为图片都是通过Flash映射的内存地址去读的,
需要用工具写入0x200000处,或者用工具合并成一个bin文件,
烧录一次后下次就无需烧录0x200000的图片了
(2)示例代码和这个屏幕的驱动代码不在gitee上,但有提供一个示例工程代码,
我这里把原本的首页的字改了
