This week, Adafruit launched an thrilling blog post demonstrating Circuit Python (CP) working “naked metallic” on the Raspberry Pi 4. This concept was touched on earlier this 12 months in an episode of our Raspberry Pi-themed podcast, the Pi Cast, by Circuit Python lead Scott Shawcroft.
Not solely is CP working naked metallic on the Pi, however the crew has additionally cooked up a demo of the system outputting terminal information to an eInk show. Girl Ada will be seen coming into information which then seems on the display 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 as these shows take somewhat little bit of time to refresh. That mentioned, the terminal output updates with no matter command or textual content was entered as quickly because the display completes the refresh course of.
As of proper now, terminal output by way of HDMI is the extent of the progress. Based on the crew, the subsequent step is to implement GPIO utilization assist. Take a look at the demo at Adafruit to see this mission in motion and get impressed for some Circuit Python creations of your individual.
