Kit Operation
The CY3210-PSoCEVAL1 kit helps in evaluating applications using the PSoC 1 family of devices.
This kit can be used to work with the different user modules provided in the PSoC Designer software
and explore hardware features that are integrated into the PSoC 1 device.
3.1
Evaluating the PSoC 1 Device
The CY3210-PSoCEVAL1 board is populated with a preprogrammed CY8C29466-24PXI part. To
evaluate the default project programmed on the board, make the following hardware connections:
■ Connect the jumper (shunt) at JP1 and JP2.
■ Connect the potentiometer (VR on connector J5) and port P0[1] on connector J6 using one of the
single-strand jumper wires (see Figure 3-1). This connects one of the PSoC pins to the potentiometer.
After the connections are made, plug in the MiniProg to the ISSP header. Connect the MiniProg to
the PC using the USB cable provided. Power the kit using PSoC Programmer. For more information
on using PSoC Programmer, see Programming Specifications and Connections on page 20. The
CY3210-PSoCEVAL1 can be powered from a DC supply jack, battery terminals, or using the
MiniProg. The PWR LED5 lights up (red) when the board is powered.
You can vary the analog input by varying the potentiometer (R7). The output is displayed on the LCD
module. LCD contrast control potentiometer (R6) can be used to vary the LCD contrast.
The PSoC MiniProg gives you the ability to program PSoC parts quickly and easily. It is small and
compact, and connects to your PC using the USB cable. During prototyping, the MiniProg can be
used as in-system serial programming (ISSP) to program PSoC devices, as shown in Figure 3-2.
MiniProg1 does not support I2C communication. The CY3240-I2USB and MiniProg3 can be used as
a USB-I2C Bridge for debugging I2C serial connections and communicating to PSoC devices.

Kit Operation
Figure 3-1. PSoCEVAL1 Evaluation Board
3.1.1
Programming Specifications and Connections
When the MiniProg is connected, you can use PSoC Programmer to program the CY3210PSoCEVAL1 Evaluation kit. Plug in the USB cable into the MiniProg before attaching it to the ISSP
header on the board. When using a USB cable with MiniProg, keep the length under six feet to avoid
signal integrity issues.
When using MiniProg, the LEDs blink at a variable rate to track connection status. The green LED
near the USB connector turns on after MiniProg is plugged into the computer and is configured by
the operating system. If MiniProg cannot find the correct driver in the system, this LED does not turn
on. After the device is configured, the LED stays on at about a 4-Hz blink rate. This changes during
programming, where the blink duty cycle increases.
The red LED (Figure 3-2) at the bottom turns on when the MiniProg powers the part. The LED is off
when power is provided by the target board.

Functional Description
The CY3210-PSoCEVAL1 Evaluation Kit demonstrates the function of PSoC 1 devices. Connect the
device to onboard peripherals such as potentiometer, LEDs, LCD, and RS-232. The board also has
additional features such as a general prototype area (bread board) and an ISSP programming
header. It provides different voltage domains; see 4.2.1 Power Supply System.
Figure 4-2. CY3210-PSoCEVAL1 Evaluation Board
4.2.1
Power Supply System
The power supply system on this board is versatile. The kit can be powered in three ways: using a
MiniProg unit, DC wall adaptor, or a 9-V battery. The DC wall adaptor must be of 9 V to 12 V, 1-A
rating unit. The onboard voltage regulator converts input 9 V/12 V into 3.3 V/ 5 V. Selection between
3.3 V and 5 V is done using jumper JP3. When the jumper (shunt) is not connected, the regulator
gives the output voltage of 5 V; installing the jumper gives a 3.3-V output.
Note Use only one power supply at a time. Do not use a power supply that is less than 7 V or
exceeds 12 V.
If the board needs to be powered via external 3.3-V or 5-V supply, the power input should be connected to the VCC sockets of the J5 connector (Figure 4-9). The external voltage must be less than
5.5 V.
Warning Any voltage input greater than 12 V connected on these headers will permanently damage the board components.

4.2.1.1
Protection Circuit
A reverse-voltage and over-voltage protection circuit is added at the expansion port on VCC lines.
The protection circuit consists of two P-channel MOSFETs on the power line allowing the power/current to flow from input to output depending on the voltages applied at the external board connector.
Figure 4-4 is the protection circuit placed between the VCC domain near the prototype board (on J5
connector) and the onboard components. This circuit disconnects or behaves similar to an open
switch if an external voltage above 5.6 V is applied on the VCC pins of the J5 connector.
Warning Any voltage input greater than 12 V connected on these headers will permanently damage
the board components.

Project Description
This project demonstrates a 12-bit incremental ADC by measuring the voltage of the potentiometer,
transmitting the conversion result on the UART, and displaying it on the LCD. The project uses the
following modules:
ADCINC: This module processes the programmable gain amplifier (PGA) output at the rate of 180
samples per second and produces the corresponding digital output.
PGA: This module is used at unity gain to supply the input to ADC.
UART: This is an 8-bit universal asynchronous receiver transmitter (UART). The clock divider VC3
generates the baud clock for the UART by dividing 24 MHz by 156. The UART internally divides VC3
by 8, resulting in a baud rate of 19,200 bps. The ADC output is sent to the PC using UART module.
LCD: This module is used to display the ADC output (hex) values. If the ADC has completed
conversion, the output is displayed on the LCD as ASCII text. The same is transmitted to the PC
through a RS-232 cable.
Note This code example (C_Example_ADC_UART_LCD) is located in the Firmware folder.

Verifying Output using LCD
When the example code is built and programmed into the device, reset the device by pressing the
RESET button or power cycling the board. The voltage of the potentiometer is measured by the ADC
and is output as a four-digit hex value on the LCD. The value displayed on the LCD should change
as the potentiometer is turned (see Figure 5-38).
Note Remove jumper JP3 to verify output at 5 V. The LCD display will not be seen at 3.3 V
operation.

Project Description
This project demonstrates how an LED blinks at a constant duty cycle using a hardware PWM.
PWM8: The clock dividers VC1, VC2, and VC3 are used to divide the 24-MHz system clock by 16,
16, and 256, respectively. The resulting 366-Hz clock is used as the input to an 8-bit PWM. This in
turn produces an LED blink period of 1.4 Hz.

5.4.1
Project Description
This project generates a sine wave using a 6-bit DAC. The sine wave period is based on the current
ADC value of the potentiometer. The project uses the following user modules:
Counter8: An 8-bit counter is used to generate an interrupt at the DAC update rate (1/64 sine wave
period). By adjusting the counter period, the DAC frequency and the resulting sine frequency can be
modified.
DELSIG8: Current ADC conversion values are used to reload counter period. ADC input voltage is
between 0 V and Vdd, depending on the potentiometer.
PGA: This module is implemented as buffer with user-programmable gain.
DAC6: This module converts digital input to analog output, which is used to generate sine wave. The
DAC output is routed to P0[5] in the chip design. When P0[5] is connected to an LED on the board
using single strand jumper wire, the LED blink period varies with the position of potentiometer. The
sine wave pattern can be observed on an oscilloscope when the DAC output (P0[5]) is connected to
the oscilloscope.

5.5.1
Project Description
This project demonstrates the Dynamic Reconfiguration capability of PSoC Designer. A set of user
modules is called a configuration. A loadable configuration consists of one or more UMs placed with
module parameters, global resources, pinouts, and generated application files. The UMs used and
the register settings can be changed easily. The application can switch in and out of configurations in
real-time, allowing greater use of the chip resources. This is similar to memory overlaying or using
more than 100 percent of the resources in an FPGA design. Imagine a vending machine where a
PSoC monitors and controls environmental conditions such as temperature and humidity, dispenses
drinks, counts money, makes change, controls LEDs and an LCD display, and implements capacitive
sensing buttons or a touchscreen interface. Now, imagine that once a day for about a minute, it
reconfigures itself such that it can send information back to a central office. This is the power of
PSoC with dynamic reconfiguration.
To add loadable configurations to a PSoC project, right-click the Loadable Configuration folder in
the Workspace Explorer and select New Loadable Configuration. A new folder is created with a
default name, Configx, where x is the number of alternate configurations.
The new configuration can be renamed based on the project. All PSoC resources (digital and analog
blocks) can be reused. A loadable configuration can be deleted if no longer required. However, the
base configuration (the default configuration) cannot be deleted.
When using dynamic reconfiguration, global parameters are set in the same manner as single configurations. However, changes to the base configuration global parameters are propagated to all
additional configurations. Therefore, global parameter changes made to an additional configuration
are done locally to that particular configuration. For instance, if global parameter #1 has a specific
value in "Base" loadable configuration, it will have the same value in "New" loadable configuration.
But not vice versa: if global parameter #2 has a specific value in "New" loadable configuration, it will
have the default (or base-specific) value in "Base" loadable configuration." The same also applies to
port pin settings.
In this project, dynamic reconfiguration is demonstrated by configuring a PWM in the digital block
DBB01 in one configuration. The same block is used to configure a PRS in the second configuration.
A Counter8 UM is placed in the base configuration that drives the PWM or PRS module based on
the configuration that is loaded. A switch on the CY3210-PSoCEVAL1 board is used to toggle
between configurations.
When the SW switch is released, the PRS configuration is unloaded (if already loaded), and the
PWM configuration is loaded. In this configuration, LED1 and LED2 are used to output the PWM
Pulse Width and PWM Terminal Count, respectively.
CY3210-PSoCEVAL1 PSoC® 1 Evaluation Kit Guide, Doc. #: 001-66768 Rev. *E
61
Code Examples
When the SW switch is pressed, the PWM configuration is unloaded and the PRS configuration is
loaded. In this configuration, LED1 and LED3 are used to output the PRS Pulse Density and PRS
Bitstream, respectively.
The APIs UnloadConfig_<configname> and LoadConfig_<configname> are used to unload and load
the required configurations
Counter8: In the base configuration, it takes a clock of 732 Hz as an input.
PRS8: The PRS configuration contains a PRS with pulse density (analogous to pulse width) and a
bitstream output that is shifted out to LED pin.
PWM8: The PWM configuration contains a standard 8-bit PWM with a duty cycle of 50 percent. Both
the pulse width and terminal count outputs are displayed on LEDs.

Project Description
This project demonstrates a PSoC project designed to blink an LED using the output of two PWMs.
The outputs are combined using an AND gate in an output bus logic block. This logical combination
results in a beat frequency of 1.4 Hz.
PWM8: Two 8-bit PWM UMs process a 93.37-kHz clock with periods of 256 and 255, respectively.
This produces the LED beat frequency of 1.4 Hz.

Replace CY8C29466-24PXI with CY8C27443-24PXI
The CY3210-PSoCEVAL1 kit includes two PSoC parts, CY8C29466-24PXI and CY8C27443-24PXI.
The CY8C29466-24PXI part is placed on the IC socket of the board when shipped. To replace the
default part with CY8C27443-24PXI, follow these instructions.
Use an IC extractor – place the ends of the extractor between the IC and the socket. Gently pull the
IC out evenly, away from the board. If an IC extractor is not available, using a nonmetallic tool, lift
one side of the IC, as shown in Figure A-4. Do not lift the IC completely because this can damage
the pins on the opposite side.
Figure A-4. Lift IC - One Side
Repeat on the other side to lift the silicon from the socket, as shown in Figure A-5.
Figure A-5. Lift IC - Other Side
Place the CY8C27443-24PXI silicon on the IC socket. Ensure that the silicon notch is aligned with
the notch on the IC socket; see Figure A-6. Press down gently to finish the replacement.
