When first powering up a 2x40 (BG Micro) display - has anyone out there every seen it displaying from left to right: 3 black blocks, 1 space, 4 black blocks (character sized) and then over 3 or 4 seconds, the blank space filling in vertical line, by vertical line - and the display turning off finally?
I haven’t yet changed the system to know that it’s gone from a 2x20 display to a 2x40; I haven’t hooked up the ICL7660 chip, to change the +5V to -2V for the proper power; I HAVE checked wiring from core to 2x40, 3 times (maybe 4) now - and it’s all correct. (Though - realized at work yesterday - I’ll have to check and see if I have the 10 pin connector plugged in correctly. 
)
I’m just hoping that I haven’t statically destroyed the display - by not being grounded when removing it from it’s case. 
Also - (remerbing reading this in the troubleshooting section) - I wondered if somehow I DO have the +B/-B connections backwards, as I DID see the backlight (dimly) come on for about 1 second and then shut off, after rebooting the core - two times.
Curious as to whether anyone else has seen this or not. Thankfully I bought 4 of the displays. :o My original intentions though, were to eventually have 2 sequencers. I’m just hoping I haven’t killed one of the displays, by not having an anti-static strap hooked up. :o
Thanks for any possible help. 
Oh! Also! Does anyone have pics up anywhere, as to how you’ve hooked UP the 2 2x40’s? I’m trying to think of a neat/clean way to do it. :o :o
