Hi,
My project (an MFC) currently successfully runs 8 x hitachi hd44780 lcd displays on my Teensy 3.6 in the std way:
(ie using 5 I/O pins for shared D4, D5, D6, D7 & RS) & then 8 additional I/O pins for the each display's EN.
As I said it works - but the wiring is a mess & absolute nightmare.
I was wondering if it was possible to run these displays over SPI or i2c?
And if yes - is it possible to run 8 at once?
Thanks
