> - display outputs gibberish characters on lines 1/3 when T2 writes to it. But I never see gibberish on lines 2/4Power up sequence? What Power up sequence? Ohhhhhhhhh, you mean *that* power up sequence.
Fred tells me the following in an email "The LCD has a particular startup sequence and this will only be done at the T2 startup."
Whereas, I took the WIKI quite literally "No configuration is necessary. The standard Tracker2 firmware will begin using the display automatically. "
So, I just plugged it in, hot. What a newbie mistake!
