shiftPWM和ATTiny85出错

Question

我在这一点上迷路了，感谢任何人的帮助！我从一个旧的GitHub下载了这个库，但我甚至不会编译它。

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，我必须对库进行以下更改...

• 减小代码大小以适应ATTINY有限的闪存空间。
• 消除了对SPI和串行硬件的所有依赖，因为ATTINY没有它们。
• 将现有的Timer0中断用于刷新触发器，因为ATTINY的定时器较少。
• 为ATTINY定义管脚和设备映射。

我还做了一些美观的更改，比如在编译时静态分配缓冲区，因为如果没有串行连接，就无法看到“内存不足”错误。

叉子就在这里。https://github.com/bigjosh/ShiftPWM-Redux

自述文件包含有关将代码从旧库迁移到新库(不难)的必要更改的信息。fork中的示例也进行了更新，以使用新的库，因此是一个很好的起点。
