Arduino due Pinout

ARDUINO DUEboard is one of the most powerful development boards in theARDUINO series。应有的板不仅具有大量功能，而且具有出色的处理速度，使其适合高级应用程序。它可以被认为是专业董事会UNO作为初学者委员会。应有的板在ARM控制器系列上开发，而其他板在Atmega Controller系列中也开发了。

Where to use ARDUINO DUE

Although ARDUINO boards are usually popular, DUE is least popular because of controller being ARM and I/O pins +3.3v OUTPUTS are not compatible with most sensors. Though it is least popular, it is most recommended when designing complex systems like CNC or 3D printer. Also, theARDUINO DUE是一个开源平台，可以获取所有相关数据和原始模块原理图。因此，您可以根据需要自定义系统。

There are few cases where DUE is chosen over other Arduino Boards:

Case1:系统处理的位置很大。uno或NANOare boards, which have a maximum clock speed of 16 MHz, so they can perform functions limited to their capabilities. They cannot process high end programs for applications like 3D printer. With 84MHz clock speed more than five times speed of UNO, DUE could do process more data than UNO or NANO.

Case2:您需要在哪里连接更多的外围设备。到期有超过54个I/O销。因此，当应用程序中有许多外围设备时，适用的是理想的。

Case3:Where application needs to provide analog output. UNO and NANO cannot provide analog output which is need in some applications. In those cases, DUE will solve the problem.

Case4:有了许多PWM和ADC输出，应有的可以运行的应用程序程序，该程序无法由其他Arduino解决。

Case5:使用CAN界面，应有的余地可用于具有高电磁干扰的系统，而其他通信可能会失败。该设施不存在于其他Arduino董事会上。

How to use ARDUINO DUE

DUE is used similar to any other development board. All that needs to be done is programming the controller and provide the appropriate peripheral to get system running. We will discuss the programming of DUE in step by step below.

DUE can be programmed by connecting both USB ports to PC. Although there are two, PROGRAMMING PORT is preferred over NATIVE USB port in order to avoid controller crashing during programming. So connect DUE to PC using PROGRAMMING port is ideal.
下载并安装Arduino IDE软件。[[https://www.arduino.cc/en/Main/Software]
接下来，获取PC和PC之间的链接。运行一个测试程序以眨眼LED。
列出要通过的要执行的功能。
将功能写为IDE中的程序。
Remember for ARDUINO IDE the program is written in ‘C’ language.
After completing the writing. Burn the program to DUE through IDE.
断开程序员的连接。提供功率并附加必要的外围设备。重置控制器后，它执行程序并提供所需的输出。
