RP2040 Camera Image Capture in CircuitPython

Did you know the RP2040 PIO peripherals can be configured for reading in camera/video data? that’s right, you can directly wire up OV7670/OV2640-like cameras to a RP2040/Pico and then read out image data into a RAM buffer (thankfully theres a ton of RAM on the RP2040) – video. We just got support into CircuitPython as well, so we can read a buffer, as seen here, then pipe it back out over SPI to a TFT. Could be great for image recognition, tinyML, DIY cameras, IoT monitoring, etc! We built up a Perma-Proto for swapping different cameras in for testing. We’re getting a little posterization-effect, which looks cool but is not on purpose, hopefully will get it sorted out very soon!

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
