Help with BW screens and RPi0

[onesojourner]

Can one of you guys explain why we need the second ground, I guess you are calling it the composite ground? I have this same board and I do not have the second ground hooked up. The screen is working but there is a lot of static and flickering. This is how I currently have it wired up. I have 3 other screens that remain black though.

Well the driver board needs ground but the pi also needs ground on the composite. The cable that comes with the screen already ties the grounds together. If you are using your own solution like i did, you have to account for this and use 2 grounds

Alright using a composite cable I was able to get 2 of my 3 screens working. I have only tried wiring things up like the image from the wiki. I will try your solution tonight.

My solution seems to make the screen run pretty hot. Does this board get very hot with the other technique in the wiki?

So far mine are only slightly warm. I have only ran them for about 5 minutes at a time though.

Can you post a picture of the board? Mine gets hot too. I have the same BW screen as this one http://www.sudomod.com/forum/viewtopic. ... =30#p30926

unfortunately I damaged that board (broke the ribbon cable) and got another one that works straight off 5v.
