This week, Adafruit launched an thrilling blog post demonstrating Circuit Python (CP) operating “naked metallic” on the Raspberry Pi 4. This concept was touched on earlier this yr in an episode of our Raspberry Pi-themed podcast, the Pi Cast, by Circuit Python lead Scott Shawcroft.
Not solely is CP operating naked metallic on the Pi, however the workforce has additionally cooked up a demo of the system outputting terminal information to an eInk show. Woman Ada may be seen coming into information which then seems on the display screen after a fast refresh.
The demo works by connecting to REPL over USB-C. This connection operates in USB peripheral mode. The keyboard enter is processed for output to an HDMI port related to an eInk show.
As a result of that is an eInk panel, there's a delay in what you see on the display screen as these shows take a bit little bit of time to refresh. That stated, the terminal output updates with no matter command or textual content was entered as quickly because the display screen completes the refresh course of.
As of proper now, terminal output through HDMI is the extent of the progress. In keeping with the workforce, the subsequent step is to implement GPIO utilization help. Try the demo at Adafruit to see this challenge in motion and get impressed for some Circuit Python creations of your individual.
