RE: [tracker2] Tracker2 with LCD display
- "What about adding this information into the Wiki?" - James VE6SRV
I edited my first Wiki page, "Connecting an LCD to the OT2m". Thanks James
for the push. :)
I did make an error though. Sorry! For some reason, the next page is to the
right of the inserted information. I am not seeing what I am missing. Well,
I guess that goes without saying, obviously it isn't there. Maybe someone
can let me know what to add. ;)
Anyway, I added the schematic that went out as an attachment on 09/17/09.
For those that have added an LCD display panel, I would ask that you review
> - 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!
