To convert a string into an integer or float, you can utilize the functions .toInt() and .toFloat(). However, the string must correspond to the respective integer or floating-point value. For instance, you can convert "1.87" into float. On the other hand, converting "Hello" into float...

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...
