Arduino Yun & GPRS Shield

[kirk.mower]

Hello:

Is it possible to use the Seeed GRPS shield with the Arduino Yun, given the difference in the pin configurations? Thanks.

Hello,
can you someone explain me every single line on the message in the picture below

thank you in advance

// demo: CAN-BUS Shield, send data
#include <mcp_can.h>
#include <SPI.h>

//Pot for adjusting value
int sensorPin = A0;
int sensorValue = 0;
int cantxValue = 0;

void [b]setup/b
{
Serial.begin(115200);
// init can bus, baudrate: 100k
if(CAN.begin(CAN_100KBPS) ==CAN_OK) Serial.print(“can init ok!!\r\n”);
else Serial.print(“Can init fail!!\r\n”);
}

//Some sample CAN messages
unsigned char msg1[8] = {0, 1, 2, 3, 4, 5, 6, 7};
unsigned char msg2[8] = {0xFF, 0x01, 0x10, 0x0A, 0x00, 0x00, 0x00, 0x00};
unsigned char msg3[4] = {0xFF, 0x01, 0x10, 0x0A};

void [b]loop/b
{
//Read the value of the pot
sensorValue = analogRead(sensorPin);
//Each CAN bus byte can store a value between 0-255.
//Dividing sensorValue by 4 puts us in that range.
cantxValue = sensorValue / 4;
Serial.print("cantxValue: ");
Serial.print(cantxValue);
Serial.println();
//Create data packet for CAN message
unsigned char canMsg[8] = {cantxValue, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00};
// send data: id = 0x123, standrad flame, data len = 8, stmp: data buf
CAN.sendMsgBuf(0x07B, 0, 8, canMsg);
delay(100);
