SD Card Shield - Required Pins

-

hi all

i have sd card shield seeed studio (v4.1 - http://www.seeedstudio.com/wiki/sd_card_shield_v4.0) , lcd shield linksprite (http://linksprite.com/wiki/index.php5?title=16_x_2_lcd_keypad_shield_for_arduino)

from of things ports overlap on shields wondering if assist highlighting ports sd card shield uses (i'm not able determine schematic on sd card shield) , if possible me change ports required on shield?

at stage playing "cardinfo" sketch within arduino software. using mega 2560.
edit - should add, can see poirt 4, 11,12,13 in use not sure if else in use (isp ports?)
regards
stephen

pin 10 should set output pin, enable spi, involves pins 11, 12, , 13. chip select pin, define spi device active receiver pin 4., pin use in sd.begin() call.

the lcd shield uses pins 4 9. why moronic piece of crap example software uses pin 13 in constructor mystery. pin 13 (fortunately) not connected lcd shield.
