Hi everyone,
I have a few of these displays around: http://www.lcdwiki.com/3.5inch_Arduino_Display-UNO
I want to use it in my project together with an ESP8266 (Wemos D1 mini) or maybe an Arduino Nano, however i can't wrap my head around how to use it that way (in terms of wiring and code).
I tried to search it up on google of course, but had no luck with that.
Could someone help me out or hint me into the right direction?
Thanks a lot!
Wiring? It looks like just plug it in. If they provide example code, start examining that code. Else You have some reading to do.
I have two of these screens. They are really made as a convenience to just plug directly into an Uno rev. 2 or rev. 3. They will also work with the Adafruit Metro ESP32-S2 as well as a few other boards out there. You could wire these up directly to something else but if you want something more simple I'd suggest a screen with an I2C interface.
That LCD uses an 8-bit parallel interface (8 data pins) plus a number of control pins. The Wemos D1 Mini seems to have only 11 GPIO pins so if it works at all it will be a tight squeeze! Some LCDs, like the popular 16x2 text LCDs, have a 4-bit mode where they only use half of the data pins. If the controller on your shield has a mode like that and you can find a library to drive it that way then you have a better chance of getting it to work on 11 pins.
