Hi all,
Just a little confused by the DC pin required by ILI9341 (and other displays). looking at the source for ILI9341_t3 and the like, this is used to switch between data and command when initializing the display (and perhaps other times commands are sent to the display).
I'm assuming that DC has nothing to do with SPI and is something specific to the display? So it's not actually 5-wire SPI, but something the display needs? Sorry - new to SPI, and also to low-level display driving!
Cheers,
Peter
