CAN-Bus sheild int fail on any Arduino except Seeeduino

WORK Arduino Mega 2560 + CAN BUS shield
1) in file "mcp_can_dfs.h" replace rows:
from

Code:

#define MCP2515_SELECT()   digitalWrite(SPICS, LOW)
#define MCP2515_UNSELECT() digitalWrite(SPICS, HIGH)

to

Code:

#define MCP2515_SELECT()   digitalWrite(SPICS, HIGH)
#define MCP2515_UNSELECT() digitalWrite(SPICS, LOW)

2) in file "mcp_can.cpp" function "INT8U MCP_CAN::begin(INT8U speedset)"
after row

Code:

SPI.begin();

insert row

Code:

SPI.setDataMode(SPI_MODE1);

In result we have:
"Enter setting mode success
set rate success!!
Enter Normal Mode Success!!
---------
CAN BUS Shield init ok!"
