How to make CAN-BUS shield (by linksprite) compatible with arduino MEGA 2560?

The CAN-BUS shield (by linksprite) work well with arduino UNO. However, when I use an arduino MEGA 2560 , it shows the CAN cannot be initialized. Like the connection method shown in website “Matthew McMillan: Using the Seeed CAN-BUS shield with an Arduino Mega”. I bent the 11,12,13 pins of shield, and used three jumper wires to connect the SPI pins between the shield and MEGA, that is 50(mega)-12(shield), 51(mega)-11(shield), 52(mega)-13(shield). Pin 10 was still as CS pin. After upload, it shows the function, “CAN.begin(CAN_500KBPS)” was not success. In the print window it shows CAN bus shield init failed. Which codes should be changed?
My codes are listed as following:
#include <mcp_can.h>
#include <mcp_can_dfs.h>
#include <SPI.h>
const int SPI_CS_PIN = 10;

void setup()
while (CAN_OK != CAN.begin(CAN_500KBPS)) // init can bus : baudrate = 500k
Serial.println(“CAN BUS Shield init fail”);
Serial.println(" Init CAN BUS Shield again");
Serial.println(“CAN BUS Shield init ok!”);

why not try to change the CS pin to the default one for Mega (which is pin 53) and see if it works....

that would be too silly to do, right?

I connected the CS pin to 53 pin of MEGA. It works! Thanks a lot.
