README
README.mdWiggleCam Camera Controller
The RP2040 board that handles timing-critical and analog work for a 4-lens camera. The Raspberry Pi runs capture and image processing, but Linux is not a real-time OS and the Pi can't drive the flash directly.
This board runs the LED flash at constant current, with the limits set in the circuit rather than only in firmware. It also debounces the shutter, decodes the EC11 encoder, and monitors battery voltage and current through an INA219. On a trigger it pulses the Pi the instant the LEDs reach full current.
The Pi drives it over I2C at 0x17, and the capture pulse returns on its own GPIO line. The 2x6 header maps 1:1 onto Pi 5 GPIO pins 1 to 12.
