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.
