3-wire SPI LCD use with u8glib
qwertygin 2012-08-13 23:52:36 5189 Views1 Replies Hello everyone!
I recently purchased the 3-wire Serial LCD Module (Arduino Compatible) module and i intend to drive it using the u8glib library.
I use Arduino Leonardo.
The u8glib requires that you provide the pinout for the following SPI lines:
Clock (sck) -> SCK
Data-In (mosi) ->SID
Chip-Select (cs) ->CS
Command/Data selection (a0) -> ?????
Optional: Reset line -> Not used.
How do i define on wich arduino pin the a0 line is connected to?
Is the A0 line actually needed to use the SPI-LCD module?
Many thanks!
