Why not buy the SPI (serial) version it’s half the price and speed nearly the same?

DrKuebel commented 5 years ago

I accidentialy bought the wrong one ;-)

G6EJD commented 5 years ago

Your problem (parallel interface) is there are not enough IO pins to drive the display even on a (say) NodeMCU. You’d need 8-data plus a clock and chip-select and a command/data selector, about 11, maybe more with reset and busy detection, that’s a total of 13, this is why SPI is more GPIO efficient. You could use the display on a UNO/MEGA if pin compatible.
