[Ovmsdev] LCD Car Mount Display

[Mark Webb-Johnson]

Having completed the v3.x hardware, and being a complete masochist for this, I’m now working with China to see what is possible as a display (for OVMS and other projects).

The idea is to have a small enclosure that includes:
A 3.5” backlit LCD display.
Four touch buttons (as touch-screen too hard to use in a moving vehicle) - Up, Down, Enter, Back/Cancel.
A WROVER32 (probably 4MB flash to keep costs down, but perhaps 16MB is possible). This has 4MB SPIRAM.
MicroSD or SD card slot (full speed 4 wire).
USB for firmware flashing and console access.
Bluetooth
Wifi
Connection for:
Power (12V regulated)
Data (async bus)
CAN (one single CAN bus)
Expansion via internal GPIO headers
OVMS firmware

This could be a display for OVMS, or in general be a very flexible form of in-car or general purpose hacker display.

The entire project would be geared towards getting the cost down. I’m trying to get an idea of what we can get this done for.

What do people think? Is this any use?

Regards, Mark.

1] Easily obtainable enclosure

The idea being to use this along with a standard car mount (perhaps magnetic - there are lots)








2] Other examples, for comparison
