An e-ink info display which displays the weather and my nextcloud calendars and tasks. So Rust Backend which pulls the data and displays a static HTML page, which will be pulled by the esp32 board. First project with rust
Are you also programmibg the esp using rust? Ive only gotten pretty basic stuff to run on embedded systems with rust despite really wishing that I could do more
Not there yet. Just started with the Backend. But i read about Rust on embedded devices. I need to do some more research, but if its a realistic Option, i will try to
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.
