help reading data from MaX110/MAX11 !!

emix

i am starting working with ADC and Basic Stamp and i hope someone could help me with this.

This is what i have but i dont know exactly if this is ok or not, because i dont receive data from data in,

if you look at the code, i do a shiftout and then a shiftin (which i dont know if its correct) and what i am reatriving is just the same data that was sent by the shiftout

so, i dont know what i am missing, timing.. enable/disable cs.
