Reboot time on CFA634

How long should I wait before sending commands after a reboot? I'm currently waiting 1000ms. Seems like a long wait.

There is not much for it to do when it wakes up, so it should not take too long.

I would guess that 100mS or 250mS would be long enough. Maybe try 100 and if that works bump it to 150 for a little margin.

Well, before I went to 1000ms, I was up to 400ms, and it would still miss operations. I got worried that even if I found the magic number, that it wouldn't work with every other LCD. I'll switch to simply clearing the LCD later when the GUI's written and I can provide a way to reboot the LCD, so it's not a huge deal.
