Description
VCP-QVGA-02 is a isual control panel to be built in
user equipment.
It is a generic de ice, i.e. the hardware is fixed and the
user can realize specific functionality by software only.
For de elopment of VCP-QVGA-02 applications
de elopment set DS-QVGA-02 is a ailable.
Applications
• Control panel for arbitrary use
• Home automation
• Access, security, heating systems,…
• Wireless control
• VCP-QVGA-02 is intended for final production.
• DS-QVGA-02 de elopment set is intended for
de elopment of VCP-QVGA-02 applications.
Key features
• Display/touchscreen unit to be built-in user equipment
• Ethernet and USB connecti ity, IQRF (wireless) interface
• Additional peripherals, interfaces and connectors

Hardware
VCP-QVGA-02 is a generic equipment, i.e. the hardware is fixed and the user can realize specific functionality by
software only. See DS-QVGA-02 documentation and demo SW for details.
Power supply
VCP-QVGA-02 is intended to be supplied by external power supply (VDD) connected ia system connector. This is
con erted to 3.3 V by internal LDO regulator.
MCU
VCP is controlled by the 32b microcontroller PIC32MX795F512LPL, up to 80 MHz, 100 pins.
Oscillators
MCU is clocked by external 16 MHz crystal oscillator which allows to reach up to 80 MHz using the internal PLL. For
minimized power consumption, RTCC operation in Sleep mode etc. secondary crystal oscillator 32.768 kHz is a ailable.
Reset
VCP reset (initialization/starting-up) can be in oked by low le el on the MCLR MCU pin ia system connector or by
software.
Sleep mode
This is intended for current consumption minimizing, especially in idle or while supplied from an accumulator. It is possible
to switch off all functions and peripherals by software.
VGA display
Display / touchscreen DI-QVGA-3.2-02 with diagonal 3.2“, 320x240 pixels RGB, 262144 colors (graphic library uses 65535
colors only), QVGA TFT LCD, transmissi e, with LED backlight and 16b data bus.
Proper display functionality requires a calibration (setting the touch sensors in accordance to display pixels) to compensate
ariations in parameters due to temperature, tolerance of parts and so on. The GW has the display factory calibrated and
this can also be done in application software whene er needed (3x3 touches in places indicated by an arrow). The
calibration is stored to the EEPROM. See the Demo software.
LED backlight can be switched on/off by the software.
EEPROM memory
Capacity: 64 kb, serial interface SPI (shared with the TR module) 1 000 000 erase/write cycles (typ.).
Micro SD interface
The VCP has the SPI interface to standard Flash memory micro SD card. The memory can be put to the standby mode by
SW. SD connector (Hirose DM3AT-SF-PEJ) is included if the VCP is a part of the DS-QVGA-02 de elopment set only.

VCP-QVGA-02
UART interface
Digital pins to connect serial UART hardware module inside the MCU are a ailable on the system connector. To connect
standards like RS-232 or RS-485 proper circuitry must be used on the user equipment.
Temperature sensor
Temperature can be measured by sensor MCP9802 with I2C interface. This IC is not assembled in standard deli ery.
External I2C device
Any de ice with I2C interface can be connected externally.
Tilt sensor
3-axis linear accelerometer LIS344AL is connected to the corresponding analog inputs. It is intended as a tilt sensor to
support portrait / landscape iew switching by SW.
TR module
IQRF wireless transcei er module in SIM card format, e.g. TR-52B is supported. It is deli ered on request only. The SIM
connector is always included.
Connectors
connector pins type
System 40 FX2-40P-1.27SVL (Hirose). Mating type: FX2-40S-1.27SVL (Hirose).
TR module 8 + 1 SIM connector + through hole soldering for possible mechanical fixation
SD card 8 DM3AT-SF-PEJ (Hirose)
I2C 5 Cable connector
Programming and debugging
Refer to the DS-QVGA-02 de elopment set.
Software
Refer to the DS-QVGA-02 de elopment set.
