Ne pomaze ti nista taj IC, to je samo shift registar. Moras prepraviti kompletno komunikaciju. 
Tvoja plocica verovatno sad koristi 7-8 digitalnih linija, treba ti manje za SPI, 3 ili 4 + napajanje naravno.

Generalno su ti SPI displeji zgodniji za upotrenu jer manje resursa zauzimaju u MCU, brza je komunikacija od paralelnog moda ali se te dva moda rada totalno razlikuju.

74HC165 je zgodan za suprotnu situaciju, kada imas MCU sa SPI a vezujes displej sa paralelnim portom, obrnuto ne pomaze.
