Description
GPS is a high-precision radio navigation positioning system based on aerial satellites. It can provide accurate geographic location, vehicle speed and accurate time information anywhere in the world and near-Earth space.
Features
- Low power consumption
- Easy to use
Specification
- Interface Type: UART
- Operating Voltage: 3.3V DC
- Dimensions: 56(L)*31(W)*13(H)mm
Usage
The following sketch demonstrates a simple application of the module.
1. You need to prepare a Crowbits motherboard, such as Crowbits-UNO board.
2. Connect the module to the D2 and D3 interface on the Crowbits-UNO board, as shown in the figure:
3. Upload the following code to the Crowbits-UNO board.
//at 9600 bps 8-N-1 //Computer is connected to Arduino/Crowduino //SoftSerial Shield is connected to the Software UART:D2&D3 #include <SoftwareSerial.h> SoftwareSerial SoftSerial(2, 3); unsigned char buffer[256]; // buffer array for data recieve over serial port int count=0; // counter for buffer array void setup() { SoftSerial.begin(9600); // the SoftSerial baud rate Serial.begin(9600); // the Serial port of Arduino baud rate. } void loop() { if (SoftSerial.available()) // if date is comming from softwareserial port ==> data is comming from SoftSerial shield { while(SoftSerial.available()) // reading data into char array { buffer[count++]=SoftSerial.read(); // writing data into array if(count == 256)break; } Serial.write(buffer,count); // if no data transmission ends, write buffer to hardware serial port clearBufferArray(); // call clearBufferArray function to clear the storaged data from the array count = 0; // set counter of while loop to zero } if (Serial.available()) // if data is available on hardwareserial port ==> data is comming from PC or notebook SoftSerial.write(Serial.read()); // write it to the SoftSerial shield } void clearBufferArray() // function to clear buffer array { for (int i=0; i<count;i++) { buffer[i]=NULL;} // clear all index of array with command NULL }
4. After the upload is successful, open the serial port monitor, the baud rate is set to 9600. The serial port will print the GPS address information.
