Very nice blog Mikhail! And it looks to be great work! Thank you for the complimentary things you said about RTEMS features.
I have a few questions. + Is this going to show up in the Qt free edition? + Any ideas on what RTEMS could do to improve our side of the hosting Qt equation? Graphics has always been a challenge. FWIW I took a stab at estimating porting Qt a few years ago. It is a large body of software and a lot is just not appropriate for most embedded devices. I got a reasonable subset to build but never got funding to do the actual work. I am quite thrilled your effort was more successful. Thanks. --joel On Fri, May 4, 2018 at 1:23 PM, Mikhail Svetkin <mikhail.svet...@gmail.com> wrote: > Hi all, > > We started some researches (including Qt on RTEMS), take a look if you are > interested. > > http://blog.qt.io/blog/2018/05/03/qt-microncontrollers-mcu/ > > > > Mikhail Svetkin > Software Engineer > > The Qt Company > Sandakerveien 116 > 0484, Oslo, Norway > mikhail.svet...@qt.io > +47 488 62 204 > http://qt.io > > <http://qt.io/> > <http://www.facebook.com/Qt> <http://www.twitter.com/qtproject> > <https://www.linkedin.com/company/the-qt-company/> > <https://plus.google.com/104580575722059274792> > <https://www.youtube.com/QtStudios> > > Best regards, > Mikhail > > On 1 May 2018 at 19:01, Kirspel, Kevin <kevin-kirs...@idexx.com> wrote: > >> Another option is to not use X11 and draw directly to the frame buffer >> device (i.e. /dev/fb0).
