  • I recently did a similar project. I have an old Chumby One device. I wrote a simple app that renders the time and date and outdoor temp and humidity. It receives the weather data over mqtt from rtl_433 running on an old wireless router with a USB sdr dongle.

    It writes the image directly to the framebuffer /dev/fb0

    I cross compiled for armv5te-unknown-linux-musleabi and it works great. Hard to get much running on 64mb of ram these days.

    I hope to get the source up on GitHub when I get some time.
