HelloDB

@Microinstance @martin-ger hi！ It's easy on platformio, just put it in the lib folder. Thanks for a great library.   

@h2zero Hi, I tried to compile in platformio and he failed ```cpp [env:esp32dev] platform = espressif32 board = esp32dev framework = arduino upload_speed = 921600 lib_ldf_mode = deep lib_deps =...

Thank you for your work. Can you provide an example of keyboard that can be used in BIOS environment

Hi, I tested the keyboard in BIOS environment. It works well, but I can't find an example of AbsoluteMouse. I'm trying to modify the Mouse library

I want to make a remote mouse, sending absolute coordinate data is easier to control it than using relative coordinate data

I added `moveTo(uint16_t x, uint16_t y, uint8_t wheel)` and modified `HID_MOUSE_ReportDesc` `HID_MOUSE_REPORT_DESC_SIZE` and still cannot control the mouse

> @valeros请帮助 @maxgerhardt Use sdcc-4.0.0 to overwrite .platformio\packages\toolchain-sdcc, you can download sdcc-4.0.0 here->[https://sourceforge.net/projects/sdcc/files/](https://sourceforge.net/projects/sdcc/files/) Also need to modify main.cpp->main.c, and add in the program: `void main(void); void (*dummy_variable) () = main;`...

I found out that I2S doesn't work at low frequency (cpu

当你主板A收到B返回的状态值时，将这个值记录到你创建的那个iot的属性 `properties_.AddBooleanProperty()`里，这样你后面询问风扇是否开启 return 的就是最新状态值了。你举例的这个需求拿 `iot/things/lamp.h` 稍微改下就可以了，init 时创建一个管理A、B串口收发的线程和一个记录状态的变量，这个变量就是用来同步状态的。
