與shiftPWM和ATTiny85錯誤

Question

我迷失在這一點，並希望有任何幫助！我從舊的GitHub下載了這個庫，我甚至無法編譯它。

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"

Consider upgrading this core.

它看起來像你的圖書館不支持ATTINY85芯片。

爲了使代碼與ATTINY兼容，我不得不作出以下修改庫...

• 減少代碼大小，以適應ATTINY FLASH有限空間內。
• 消除SPI和串行硬件的所有依賴，因爲ATTINY沒有它們。
• 由於ATTINY的定時器較少，因此使用現有的Timer0中斷刷新觸發器。
• 定義ATTINY的引腳和設備映射。

我也做了一些美學改變，如在編譯時靜態分配緩衝區，因爲沒有串行連接將無法看到「內存不足」錯誤。

叉在這裏... https://github.com/bigjosh/ShiftPWM-Redux

自述包括在你的代碼進行必要的更改信息，從舊庫移動到新的（不硬）。叉子中的例子也被更新爲與新庫一起工作，所以這是一個很好的起點。
