Description
The STEVAL-IPC002V1demonstration board is a
battery-operated hand-held parking ticket vending
machine system with a thermal printer interfaced
with the STM32.
The objective of this demonstration is to generate
and print parking tickets for different types of
vehicles. The system can be easily modified for
other applications that require paper printing
directly from the microcontroller, such as PoS-
based applications, railway/bus ticket printing and
stand-alone printers.
