Thanks for reply but still u didn't answer my questions. What did i write about parallel ports and pics are correct?
I read at least 5 times the datasheet but still I didn't understand
; maybe because of my English....
CS==> Has to be high to select
SDI==> Terminal address ( 001 or 010 etc... )
CLK==> What does it do and what has to be?
CS==> Has to be low to finish
Am I right?
