The Display

About the Display. I will use GU280x16G-7000 I found on eBay listed item form UK guy. This display manufactured by Noritake Itron. This display capable of two interface types, Parallel and Asynchronous Serial Interface A.K.A RS232.

The controller

I choose ESP-01S. The reason started from my want. I want to make IoT powered internet VFD clock. A long time ago I got my first Noritake Itron VFD from old Sony car stereo player. Unfortunately, At that time I'm familiar with MCU and I just have very very basics electronics skill like soldering, LED and battery. I can't control it. Also datasheet is secret of Noritake Itron. I ask they for the datasheet and they said it's the custom build for exclusive customer. The part number is MN15439A.

ESP-01S has 1MB of Flash. That's enough to fits 8 280x16 pixels bitmaps easily. but in this case I only do for 4 bitmaps. I use noisetexturegenerator.com to generate 280x16 pixels bitmap then convert using tool from Noritake Itron to 280x16 pixels hex code.
