GDEY075Z08 requires DESPI-C02 RESE to be set at '3' #104

I've just assembled everything using an GDEY075Z08 board, a DESPI-C02, and I was wondering why I couldn't get any display output.

After switching the RESE switch to 3, the display came to life. Maybe the info can be updated to reflect this?

Hmmm... I don't have that specific panel, so it's hard for me to confirm, but every place I check says otherwise.
