#LetsDriveLCD [15] – 192128A

This screen was sent to me by Grassmover. But I havn’t played with it since then. I tried to drive it yesterday night, and found out that the VEE is wrong (3.xV), it should be a negative voltage. Then I found the inductor was broken, so I replaced one. Now it is working correctly except for one missing line.
