cpy9-rp2040-demos

CircuitPython demos running on various RP2040 based boards.

Raspberry Pi Pico

This is the original Pico with Micro-USB port and 2MB flash.

• RGB matrix
  • Analog clock, uses displayio and Adafruit's turtle graphics
  • German Word clock. Inspired by an English Word clock, by VPTechOps.
• NEOpixel matrix
  • Fire demo, based on Fire2012 algorithm by Mark Kriegsman
• Pico-LCD-0.96

Raspberry Pi Pico-W

This is the enhanced Pico with Micro-USB port, 2MB flash and an onboard WiFi chip.

• The following GPIO pins are used for communicating with the WLAN chip (CYW43439):
  • GP23 - wifi power
  • GP24 - SPI data
  • GP25 - SPI CS
  • GP29 - SPI clock

WaveShare RP2040-Matrix

This is a tiny Pico clone with USB-C port, 2MB flash and a 5x5 NEOpixel matrix.

• Tiny rainbow demo, based on an Adafruit example
• Tiny fire demo, also based on the Fire2012 algorithm by Mark Kriegsman

WaveShare RP2040-Zero

This is a tiny Pico clone with USB-C port, 2MB flash and a single NEOpixel.

WaveShare RP2040-One

This is a tiny Pico clone with USB-A port, 4MB flash and a single NEOpixel.

WaveShare RP2040-ETH

This is a tiny Pico clone with USB-C port, 4MB flash and an onboard Ethernet interface.

• some usage hints

WaveShare RP2040-LCD-0.96

This is a tiny Pico clone with USB-C port, 2MB flash and a 160x80 pixel colorful LCD display. Additionally a Li-Ion charger is available.

• some LCD demos (by richteel); use adafruit_st7735r as display driver

WaveShare RP2040-LCD-1.28

This is a tiny Pico clone with USB-C port, 2MB flash and a round 240x240 pixel colorful LCD display. Additionally a 6-axis sensor and a Li-Ion charger are available.

• some LCD demos (by todbot); use gc9a01 from the community bundle as display driver

  • Hello and Circles demo, by Tod Kurt
  • Gauge and Needle demo, by Tod Kurt

• 6-axis sensor QMI8658A

VCC-GND YD-RP2040

This is a Pico clone with USB-C port, 16MB flash, user button and a single NEOpixel.

• Pico DVI
  • Slide show demo. The "YD-RP2040" has 15MB free on the CIRCUITPY drive, which is great for a slide show. But you need to install the CircuitPython firmware for the "Raspberry Pi" Pico, as the picodvi module is only included there.

WaveShare RP2040-PiZero

This is a Pico clone with size and features similar to the Raspberry Pi Zero. The board has two USB-C ports, a mini-HDMI port which can be used with the picodvi module and a SD card slot.

• Pico DVI
  • Blinking Circles demo, by Tod Kurt
  • Spirograph demo, also by Tod Kurt

Hardware Add-Ons

DVI-Sock

This is an add-on board for the Pico which uses an HDMI connector to send DVI signals to a digital monitor.

WaveShare Pico-LCD-0.96

This is an add-on board for the Pico with a 4-wire LCD (ST7735S), a digital joystick and 2 user buttons. See the wiki for more details.

• pin-out of the 4-wire LCD is similar to the RP2040-LCD-0.96; use adafruit_st7735r as display driver
