/* Keyboard test For the Arduino Leonardo, Micro or Due Reads a byte from the serial port, sends a keystroke back. The sent keystroke is one higher than what's received, e.g. if you send a, you get b, send A you get B, and so forth. The circuit: * none */ #include "...
1、UsbKeyboard库中,usbconfig.h里面可以更改USB接线的引脚定义,下面给出一个大概解释(下面的PORTD是指AVR单片机的PORTD,要查询 Arduino原理图才能得到是Arduino的哪个引脚): #define USB_CFG_IOPORTNAME D USB输入输出引脚使用AVR单片机的PORTD,如果改成B就是使用PORTB #define USB_CFG_DMINUS_BIT 4 USB的D-接P...

In the previous tutorial, we learned to blink LED by using the delay method. That method blocks Arduino from doing other tasks. In this tutorial, we are going to learn another method to blink LED without blocking other tasks. The detail instruction, code
Lots of microcontrollers these days have USB ports on them, to program or debug, act like a keyboard or disk drive, or simply send data between a computer and your firmware. But did you know that you can also add a USB Host port? That means that your microcontroller project can have a...
It is for the simple assembly of a project with keyboard input and VGA output with only four components: - Keyboard - Monitor - Arduino - NGT31 It is designed to be sleek, sturdy, and simple. What does it/can it do? At the very basic, it can re...
