Quick demonstration of interfacing with an OV2640 camera from the Raspberry Pi Pico (RP2040).

Captures images in CIF resolution (352 by 288) and sends them to a computer over the UART. Images can be captured and the camera's registers read/written from a small IPython shell.

python shell.py [serial port]

Footnotes

1. Missing on some breakout boards like the "red" board. Leave unconnected for internal clock. ↩

2. Likely require I2C pullups unless breakout board provides them. Even so, adding a 10k pullup won't hurt. ↩ ↩²
