First apologies if this post is not formatted correctly, it’s from my phone.

I just spent a frustrating 2hrs trying to get this lcd to work with my Wemos D1 mini:

They actually sent me this LCD which is different from the Ebay post:

According to the seller:

Specifications:
Driver IC: ST7735
Resolution: 128 x 128 pixels

IO interface:
RESET --directly to the microcontroller IO
CS --directly to the microcontroller IO
A0 --IO control registers select
SDA --IO control data transmission
SCK --IO control SPI bus
LED--High Level 3.3V backlight on

I’ve tried many different ways and when running ST77xx library example and editing the pin numbers, nada.

I’ve got two displays so I don’t think it’s hardware.

Going to try again in the morning, any advice appreciated.
