Has anyone explored XOD support for LittlevGL (https://littlevgl.com)? - an open-source embedded gui library that allows simple construction of touchscreen interfaces.
This would complement the excellent 4D Systems libraries built for XOD - by gabbapeople/4d-ulcd/ and bradzilla84/visi-genie-extra-library. These tools are hugely enabling - providing a code-free development environment for building sophisticated user interfaces for low cost, DIY instrumentation - and we’ve been using these for training in the international Biomaker programme (https://www.biomaker.org).
LittlevGL offers support for constructing new interfaces - with support for a wide range of low cost touchscreens. For our African programme, we’d like to support integrated Arduino-touchscreen devices like: https://www.aliexpress.com/item/32964204802.html
(This would make the hardware much cheaper and more accessible (1/5 the price) than our current version, that relies on a 4DS touchscreen - https://www.biomaker.org/2019-starter-kit).
If anyone is interested in this (it would help out a lot of African students!) - I can help out by seeding the effort with hardware…just drop me a note.
