Garbage shown during N18 initialization

During the first power up of N18 module I can see some garbage being displayed for 1 second or so. Can this be avoided?

Ooh! Cross your eyes a bit and you can see the dolphin!

It’s not a perfect fix, but I just put a n18.SimpleGraphics.Clear() in the ProgramStarted.

@ mhectorgato - It does not fix it, I am already using it.

@ iamin - Looking at the driver I don’t see much we could do. As soon as the we release the reset line, we configure the display and then clear it.

You could modify the driver and combine some of the WriteData/WriteCommand calls when configuring so you’re not jumping between native and managed so much. You can’t combine them into one call through since WriteCommand/WriteData need to set the RS pin a certain way.
