Photo

This is the firmware for a simple thermocromic selfie camera based on

  • A OV7670 camera module (without FIFO),
  • A STM32F103C8T6 microcontroller, and
  • A LTP1245 thermal printer module.

Apart from that, only a level shifter for the thermal printer (which needs 5 V signals), a motor driver for its stepper, a pullup for its thermistor, and a MOSFET for turning all power off are needed.

If an SD-card is connected, all photos are also stored there as 2-colour (dithered) BMP files.

More details can be found here.
