Question

我在这一点上迷了路，并感谢任何帮助！我从旧的GitHub下载了这个库，我甚至无法编译它。

Arduino: 1.6.6 Hourly Build 2015/10/14 10:42 (Windows 8.1), Board: "ATtiny 

x5 series, ATtiny85, 8 mhz (internal), B.O.D. Disabled"

Warning: platform.txt from core 'Arduino SAMD (32-bits ARM Cortex-M0+) Boards' contains deprecated recipe.ar.pattern="{compiler.path}{compiler.ar.cmd}" {compiler.ar.flags} {compiler.ar.extra_flags} "{build.path}/{archive_file}" "{object_file}", automatically converted to recipe.ar.pattern="{compiler.path}{compiler.ar.cmd}" {compiler.ar.flags} {compiler.ar.extra_flags} "{archive_file_path}" "{object_file}". Consider upgrading this core.

看起来您的库不支持ATTINY85芯片。

为了使代码与ATTINY兼容，我不得不对库进行以下更改......

缩小代码大小以适应ATTINY限制的FLASH空间。
消除了对SPI和串行硬件的所有依赖性，因为ATTINY没有它们。
使用现有的Timer0中断进行刷新触发，因为ATTINY的定时器较少。
定义ATTINY的引脚和设备映射。

我还做了一些美学上的改变，比如在编译时静态分配缓冲区，因为没有串行连接就没有办法看到“内存不足”错误。

叉子在这里...... https://github.com/bigjosh/ShiftPWM-Redux

自述文件包含有关您的代码从旧库移动到新库（不是很难）的必要更改的信息。 fork中的示例也会更新以使用新库，因此这是一个很好的起点。
