I get emailed pretty often how to build this, so I decided to just build an .elf file and upload it here. I just tried the makefile using the latest stm32cube 1.17.0 and it seems to build OK with some minor makefile modifications 7 years later, the changes are pushed to master :)
Unfortunately I don't have the 141T any more to test this, but I verified it runs on the dev board and the GUI shows up OK.
