### AI overview

A Rust example collection demonstrates programming the Adafruit Feather RP2040 ThinkInk, including its LED, NeoPixel, e-ink displays, sensors, OLEDs, and LCD. The panels were tested on hardware, and the examples record refresh times. USB CDC logging uses the RP2040's second core to keep serial output flowing during lengthy panel refreshes.

### Source excerpt

Developer Mariusz Jurgielewicz has published a Rust example collection on GitHub for the Adafruit Feather RP2040 ThinkInk. The repository started from the rp2040-project-template and covers the onboard red LED on GPIO 13, the NeoPixel, text and graphics on the e-Ink display, dithered tri-color and four-color images, a BME280 over STEMMA QT, SSD1306 and SH1107 OLEDs, [...]
