Hello cmdrDatalink, I want you to help me test my principle. I do about FakeGrayscale for the GU7000 display series. you can checkout here https://github.com/TiNredmc/FakeGrayscale .Did you have the compatible GU7000 series display ?. In the code I use Async interface with ESP-01S and planned to use with GU280x16G-700 https://www.ebay.com/itm/NORITAKE-ITRON-GU280X16G-7000-VFD-MODULE-BRAND-NEW/232628526042?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649 . but the code won't fit in arduino based on ATMEGA 8bit (EEPROM too less). I designed for ESP-01S but can be use on other ESP8266 as well. I hope I can reach out to you.
