I have an embedded linux system with framebuffer only. Normally a Qt Application is running. During update situation the application is stoped and I would like to use the framebuffer device to show simple text and a progress bar.
The whole thing should run out of a C/C++ application (not a shell/script) and should be as lightweight and with as less dependencies to the OS as possible. I will not need any keyboard, mouse, touchscreen or other input, just output to framebuffer.
Does anyone have a tool recommondation for me? Thanks :)
