fontconvert需要至少两个参数:一个字体文件名(例如一个可伸缩的TrueType矢量字体)和一个大小,以点为单位(72点= 1英寸;代码假设屏幕分辨率类似于Adafruit 2.8” TFT显示)。输出应该被重定向到一个。h文件…你可以叫它任何你喜欢人名字,但应具用一定的描述性:./fontconvert myfont.ttf 12 > myfont12pt7b.h...

37款传感器与执行器的提法,在网络上广泛流传,其实Arduino能够兼容的传感器模块肯定是不止这37种的。鉴于本人手头积累了一些传感器和执行器模块,依照实践出真知(一定要动手做)的理念,以学习和交流为目的,这里准备逐一动手尝试系列实验,不管成功(程序走通)与否,都会记录下来—小小的进步或是搞不掂的问题,希望能够抛砖引...
