Only pin swap done by default is the PWM output pins. This is done to prevent them from "colliding" with other peripherals. Uno WiFi: This pinout is 100% compatible with the Arduino Uno WiFi Rev2 hardware. If you have code that's written for the Uno WiFi Rev2 it will work without ...
上传文件成功后会自动加载,并在output区显示转换结果。可以点击下方的Copy output to clipboard一键复制转换结果。 ② 创建字库头文件 最后一步了!! 新建一个空白.h文件,名称建议使用全英文标识的“字体”+”字号来表示“。 例如本文转换的 华光准圆 字体,大小为20。

The Arduino Mega, which provides a great deal more computational power and pins for input and output, is also an excellent choice. There is also the Arduino Nano, Pro, and the Pro Mini, all of which are smaller and easier to operate; you might explore these later after you’ve grown ...
