16 bit conventor


hello,
i trying connect tft screen arduino nano.

the problems there enough digital pins.
i googled "serial 16 bit" , found this: http://www.fairchildsemi.com/ds/74/74f675a.pdf.
is thisvrealy need?

thank you.

yes.  using shift register add output pins common practice.  shiftout() function help.  you'd use shiftout() twice in main_write_data() function send data shift register.
