1.与Arduino共用生态，降低学习门槛，简化开发过程。 2.关键部分使用了 寄存器+宏 的优化方式，减少函数调用开销，提升运行效率。 3.简化的Arduino框架，相对stm32duino与HAL库，拥有更小的代码体积、更快的编译和执行速度。

Based on the Arduino Pro Micro, this hand-wired pad is unique in that a single press of any of its 16 keys can virtually “type” out multiple lines of text. In this case, it’s a capability ...
