i tried to build a wrapper for library from
https://github.com/rene-mt/esp8266-oled-sh1106/
i am not sure it is working well because we have to manage wrapper with 2 libraries and at last we have 2 types of callback not easy to manage.
Original project from Arduino to test this library was adapted to B4X to test wrapper for B4R.
Compilation of this B4R project is OK, but now we need tests with SH1106 and i don't have one.
if someone want to try and give feedback he will be welcome
