Here is the compressed firmware link http://vonger.cn/misc/screen/20200628.touch.bin.xz, upgrade then it is able to work directly 🙂 Just need two files to work, one is the fbusb.ko driver for touch and USB data transfer, another is /root/demo which is the littlevgl demo application.

New Screen with touch API is simpler, please check https://vocore.io/screen.html for more details.
