（二十六）msp430进阶：XBee S2（ZigBee）与MSP-EXP430G2 TI Launchpad连接

提取库并将其添加到Energia IDE的库文件夹路径中。

有关如何将自定义库添加到Enegia IDE并使用其中的示例的信息，请参阅    “基础知识”部分中的“ 将库添加到Energia IDE ”。

在这里，我们通过修改作者给出的用于接收S2模块的IO样本的示例程序来创建。这些修改基本上取代了带LCD的串口进行调试，因为只有一个串口可用，并且在使用软件串口时无法使用。

程序

#include <XBee.h>
#include <LiquidCrystal.h>

/* Create object named lcd of the class LiquidCrystal */
LiquidCrystal lcd(10, 9, 8, 14, 13, 12, 11);  /* For 4-bit mode */

XBee xbee = XBee(); /* Create an object named xbee(any name of your choice) of the class XBee */

ZBRxIoSampleResponse ioSamples = ZBRxIoSampleResponse(); 
/* Create an object named ioSamples(any name of your choice) of the class ZBRxIoSampleResponse */

bool lcd_clear = 0;
bool xbee_sample = 1;

void setup() {
  Serial.begin(9600); /* Define baud rate for serial communication */
  xbee.setSerial(Serial); /* Define serial communication to be used for communication with xbee */
  lcd.begin(16,2);  /* Initialize 16x2 LCD */
  lcd.clear();  /* Clear the LCD */
  lcd.setCursor(0,0);  /* Set cursor to column 0 row 0 */
  lcd.print("XBee Demo"); /* Print data on display */
  delay(1000); 
  lcd.clear();
}

void loop() {
  bool analog, digital;
if(lcd_clear)
  {
    lcd.clear();
    lcd_clear = 0;
    xbee_sample = 1;
  }
if(xbee_sample)
  {
    lcd.setCursor(0,0);
    lcd.print("POT : ");
    lcd.setCursor(0,1);
    lcd.print("Switch : ");
    xbee_sample = 0;
  }
  xbee.readPacket(); /* Read until a packet is received or an error occurs */
if(xbee.getResponse().isAvailable()) /* True if response has been successfully parsed and is complete */
  {if(xbee.getResponse().getApiId()==ZB_IO_SAMPLE_RESPONSE) /* If response is of IO_Sample_response type *//* Get the IO Sample Response */
if (ioSamples.containsAnalog()) { /* If Analog samples present in the response */
        analog = 1;
      }else0;
      }
if (ioSamples.containsDigital()) { /* If Digital samples present in the response */
        digital = 1;
      }else0;
      }      
/* Loop for identifying the analog samples present in the received sample data and to print it */if(analog)
      {for (int i = 0; i <= 4; i++) { /* Only 4 Analog channels */if (ioSamples.isAnalogEnabled(i)) { /* Check Analog channel mask to see if the any pin is enabled for analog input sampling */
            lcd.setCursor(6,0);            
            lcd.print(ioSamples.getAnalog(i),DEC);
            lcd.print("   ");
          }
        }
      }else6,0);            
        lcd.print("No Data");
      }
