CONNECTING THE SYSTEM
The development system box contains the development system, CD and a serial
cable.
NOTE: Jumper JPP has to be in the upper position when you work with the
development system. It should be set to the lower position only when the
development system is used in certain applications when the programmer is
no longer needed.
Step no.1 The first thing to do is to take the system out of a box and to connect
the PSoC programmer to the development system, using the flat cable. Connect
one end of the parallel cable to the parallel port of the computer, and its other end
to the PSoC programmer.
Step no.2 Second step is to connect the power supply. It can be AC or DC, as
desired, and the voltage should be between 9V and 12 V. The figure below illustrates the first contact with the development system.
Step no.3 Install the PSoC prog software.

DESCRIPTION OF THE DEVELOPMENT SYSTEM
POWER SUPPLY AND THE RESET CIRCUIT
For all the elements in the development
system to work properly, it is required to
have stabilized +5V. With PSoC system, it
is achieved by using the power stabilizer
LM7805. Because of the increased dissipation which occurs at higher current consumption, stabilizer is set upon the appropriate cooler. Diode POWER indicates that
the power is on.

SWITCHES AND THEIR PURPOSE
The purpose of DIP switches on the system is to establish or break the connections
between the microcontroller and the development system peripherals. DIP switches divide into two groups: SW2 and SW3.
The first group, SW2, connects microcontroller I/O lines to the digital thermometer, I2C bus, serial RS-232 and RS-485 communication circuits and the mini
speaker.
The second group, SW3, conects the appropriate microcontroller pins to SPI communication bus, driver MAX7219 for 7-segment LED display, CAN communication lines and the potentiometer P2, whose voltage can be read thanks to the internal A/D converter.
The following tables symbolically display the organization of DIP switches.

LED DIODES
The system has 8 diodes that are connected to the appropriate microcontroller via
port 3. These diodes are ordinarily used in the first phase of the work, but they are
also used for the later indications of the program flow. Diodes’ looks is given on
the figure below. The way to connect the LED diodes to the microcontroller is

DIGITAL THERMOMETER DS1820
DS1820 digital thermometer, with temperature range of -55 to 125 C, can be used
for measuring enviroment temperature and also for experimenting. It is very accurate and easy to connect. It should be set in the 3-pin socket, beneath the power
connector of the development system. Picture 13. shows how to connect digital
thermometer and the microcontroller on the development system.

CAN CONTROLLER - MCP2510
This type of communication was initially intended for the auto industry, but it has
proven so well that it soon found other industrial applications. It involves multiple
participants like RS485 communication. Components for CAN communication are
manufactured by many companies. Here we used models PCA80C250 by Philips
and MCP2510 by Microchip. When using the CAN controller, SW3 switches
have to be set as shown on the following pictures.

DIRECT PORT ACCESS
All microcontroller pins can be used as either input or
ouput.
Port pins can be accessed directly from the left side of
the development system using the flat cable. In this
way, values from external elements can be transferred
via pins of appropriate ports.
