Question

我正在尝试验证ADS1198和Arduino Due中的Arduino代码。即使我在开头定义了两个串行端口（现在我给出了注释），也会出现错误显示“ Serial1”未命名类型。如何处理此错误“ Serial1”未命名类型”。我如何在ArduinoDue上定义这两个端口，以便成功地编译。

#include <ads1298.h>
#include <Base64.h>

// Minimal sketch for connection to ADS129n family. Load this script and open Tools/SerialMonitor. 
// You should see text like this
// Device Type (ID Control Register): 62 Channels: 8
// If you see "Channels: 0" then check your wiring

#include "ads1298.h"
#include "adsCMD.h"
#include <Base64.h>


#include <SPI.h>  // include the SPI library:
int gMaxChan = 0; //maximum number of channels supported by ads129n = 4,6,8
int gIDval = 0;   //Device ID : lower 5 bits of ID Control Register

int activeSerialPort = 0; //data will be sent to serial port that last sent commands. E.G. bluetooth or USB port
const int kPIN_LED = 13;  //pin with in-built light - typically 13, 11 for Teensy 2.0.

//start serial port

Serial.begin(115200); //use native port on Due

Answer 1

Serial1.begin(115200)和Serial.begin(115200)需要放在一个函数中。将它们放在setup（）中。

'Serial1'没有命名类型-arduino中的错误
