STEVAL-IPC002V1 demonstration board
for parking ticket vending machine
Introduction
A parking ticket vending machine is a hand-held, battery operated device, inside of which a
thermal printer is interfaced with the STM32 microcontroller from STMicroelectronics. This
document focuses on the STEVAL-IPC002V1 demonstration board, whose objective is to
print and generate parking tickets for different types of vehicles. The application can easily
be modified to suit other applications where paper printing is to be managed directly by the
microcontroller, such as POS-based applications, railway and bus ticket printing
applications, standalone printers, and the like.

The thermal printer has an in-built stepper motor for thermal paper feeding, paper
movement, and so on. The stepper motor is controlled by a dedicated stepper-motor driver
with an SPI interface. The system operates on two Li-Ion batteries and an optional DC
adaptor. On-board battery chargers are available to charge the batteries from the DC
adaptor. The data to be printed is entered by way of touch keys, and can be verified on an
alphanumeric LCD.

Hardware design
Figure 9.
Block diagram of an STM32-based parking ticket vending machine
As shown in Figure 9, the principal system controller is the STM32 microcontroller.
Figure 12 and Figure 13 show the power management blocks in more detail.
4.1.1
Microcontroller(STM32)
The STM32 is a 32-bit MCU based on the popular ARM 32-bit Cortex™-M3 CPU running at
72 MHz with a performance of 90 DMIPS with 1.25 DMIPS/MHz. The microcontroller
incorporates single-cycle multiplication and hardware division functions. It has 80 fast
general-purpose IOs to enhance the overall performance. The IOs are 5-volt tolerant.
The microcontroller has several communication interfaces, including multiple I2Cs, USARTs
(4.5 Mbps) and SPIs, a CAN 2.0B active interface and a USB 2.0 interface. For more
information, go to http://www.st.com.
The microcontroller works on a single voltage ranging from 2 to 3.6 V, unlike some other
microcontrollers that require a dual voltage. In this application the system operates at 3.3 V.
4.1.2
Battery connector
B1+ and B1-, B2+ and B2- are the four pins of the battery connector. Two Li-Ion batteries of
3.7 V and 1800 mAh each are to be connected with correct polarity.
4.1.3
Thermal printer (FM205-HS)
The thermal printer is a compact, high-speed thermal line dot printing mechanism. It can be
used with a measuring instrument and analyzer, a POS, a communication device or a data
terminal device.
12/30
Doc ID 16916 Rev 1
UM0886
System overview
The paper is fed in a forward direction when the motor shaft is rotating in the normal
direction (clockwise) as seen from the motor gear side. The motor is driven by a 2-2 phase
excitation, constant-current chopper method and feeds 0.125 mm of paper (equivalent to a
single dot pitch) every two steps of the motor drive signal. It is not possible to print while the
motor is rotating in the reverse direction.
Excitation sequence
As shown in Figure 10, the printer feeds the paper in the normal direction when the motor is
excited in the order of step 1, step 2, step 3, step 4, step 1, step 2... On the other hand, to
rotate the motor in the reverse direction, the motor must be driven in the reverse order: step
4, step 3, step 2, step 1, step 4, step 3, etc.

Figure 11. Timing diagram for excitation sequence
4.1.4
Alphanumeric LCD
A 16 by 2 cm alphanumeric LCD displays the entries entered through the keypad.
4.1.5
EEPROM
The EEPROM maintains records and stores the last 20 entries.

UM0886
S-Touch-based keypad
The demonstration board incorporates an S-Touch keypad based on the STMPE1208SQTR
to navigate through the menus. This keypad is a 12-key daughterboard. Figure 3 shows the
placement of the keys.
4.1.7
Power supply unit
The power block is the main module of any hand-held system. This application requires
several voltages (3.3 V, 5 V, 6.5 V) to drive the various board components. The board can be
used in standalone/hand-held mode with two batteries. The circuit is implemented so that
the batteries are charged individually and in parallel by dedicated battery chargers, and
while discharging (application running on the batteries) they are connected in series. This
switching is done through a relay.
If the DC adaptor is plugged in, the voltage from the voltage regulator output excites the
relay, which changes the series connection of the batteries to a parallel connection and all
the power is taken from the adaptor.

●
Start printing: the thermal printer starts printing stored data.
●
Set Date: modify the date and time of the system.
●
Set Entry Type: entry type 'Pass' or 'Single' is stored in the user buffer data.
●
Set Vehicle Type: the vehicle type is 2 WHL, 4 WHL or Heavy, and is stored in the user
buffer data.
●
Set Vehicle Number: the system stores the last 4 digits of the vehicle number entered
by the user.
Once all initializations are complete, various flag statuses are continuously checked within
the main state machine. When a key is pressed on the keypad, an interrupt is generated and
corresponding actions are taken by the firmware.
