gu128x32-800's Issues

How to make it works on RPI 1(26-pin header) with GU128x64-800B?

Hello, I recently owned an GU128x64-800B and managed to make it working on a RPi 1(26 pin layout) I found it's a very helpful project. But until now I couldn't make it display any pixel on my GU128x64-800B. I changed GPIO pin order to fit my own setting(without FRP pin connected). And changed display UG_init parameter:
