Arduino 运行Attiny85的代码，带有集成了RGB LED的WS2812
我正在尝试使用此芯片： 。。。fgodFpsAow + 阁楼85 我使用的代码如下所示，它与Arduino配合使用效果很好，但与Attiny85配合使用效果不佳（只需打开并保持在绿色和黄色之间）。有什么想法吗？谢谢 我的ATtiny设置为8MHz，Neopix.h库中有800Khz的数据流 代码如下Arduino 运行Attiny85的代码，带有集成了RGB LED的WS2812,arduino,led,Arduino,Led,我正在尝试使用此芯片： 。。。fgodFpsAow + 阁楼85 我使用的代码如下所示，它与Arduino配合使用效果很好，但与Attiny85配合使用效果不佳（只需打开并保持在绿色和黄色之间）。有什么想法吗？谢谢 我的ATtiny设置为8MHz，Neopix.h库中有800Khz的数据流 代码如下 #include <Adafruit_NeoPixel.h> /* WS2811/Neopixel pattern switcher for ATtiny85 (and Arduin
