卤煮不死心,继续找,终于发现UNO可以模拟软串口,可以定义任何的数字引脚为软串口,好吧,那继续搞吧,这时候卤煮再次说明下,arduino自带的示例库非常之强大,很多代码可以直接打开示例直接复制黏贴了用,我们只要在示例里面找到SoftwareSerial然后打开Example就行了,摸索一下,就大概知道怎么改了,改动部分为圈出来的部分(左侧为...

2、UNO开发板 (1)将开发板接入Windows UNO 开发板使用的CH340G作为USB与Windows接口, ▲ UNO 开发板 使用USB电缆将UNO开发板接入PC,此时在Windows中出现了USB-SERIALCH340(COM31)串口。 ▲ 接入系统之后出现的CH340虚拟串口 (2)修改Arduino设置 将Arduino的设置中的端口修改为 COM31,重新...
Serial.println("Couldn't find RTC"); // rtc.adjust(DateTime(F(__DATE__), F(__TIME__))); if (! rtc.isrunning()) { Serial.println("RTC is NOT running!"); // following line sets the RTC to the date & time this sketch was compiled rtc.adjust(DateTime(F(__DATE__), F(__T...
Unzip the example and load the sketch ArgusController.ino into the Arduino IDE. Compile it, make sure the Arduino board and the serial port for your Arduino Nano or Uno are setup correctly within the IDE, then press upload button to program the sketch into the hardware. After that the devi...
Arduino Uno我们将使用 Arduino Uno 搭配我们的树莓派。为什么?首先,它是一个实时处理器。Arduino 直接与引脚和连接的外设通信。不存在操作系统或程序层抽象导致的延迟。第二,它提供了更多的引脚。其中包括我们添加的六个模拟引脚和六个基于硬件的 PWM 引脚。它是“基于硬件”的,因为电路板是实时的,我们可以在任何...

This example code is in the public domain. 此示例代码位于公共域中。 https://www.arduino.cc/en/Tutorial/BuiltInExamples/Graph */ (3)设置函数 void setup() { // initialize the serial communication: 初始化串口通信 Serial.begin(9600);
Arduino Serial Begin: Multiple Serial Ports For Arduino boards with more than one serial port the HardwareSerial class will define numbered Serial objects; For a single Serial port (Arduino Uno/Nano) you write: Serial.begin(115200); For multiple Serial ports you write ...
The Arduino Uno board has one UART that you can use either with a USB cable or from the RX/TX pins (don’t use it with both at the same time). Some boards have more available UARTs. For example the Arduino Mega has different Serials (Serial, Serial1, Serial2, Serial3) and the Ar...
