Updated guide: Capture JPEGs with @Adafruit @CircuitPython
Jeff Epler demonstrates the recently added JPEG capture mode available with CircuitPython and OV2640 camera modules:
The OV2640 camera module can also capture JPEG images up to 2 megapixels (1600×1200 pixels). This still requires a large buffer (of width×height÷5 bytes, or 384,000 bytes for a 2-megapixel image), so the demo below is coded for the Kaluga development board together with the MicroSD card breakout board+.
Load CircuitPython 7.0.0-alpha.4 on your Espressif Kaluga devkit and check out the new guide page!
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.
