Kit Operation
3.2.1
Programming Specifications and Connections
When the MiniProg is connected, you can use PSoC Programmer to program the CY3214PSoCEVALUSB 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.

Character LCD Module
86%&RQQHFWRU
/('V The kit has a character LCD module, which goes into the character LCD header, P8. The LCD runs
on a 5-V supply and can function regardless of the voltage on which PSoC is powered. There is a
zero-ohm resistor setting available on the LCD section making it possible to convert it to a 3.3-V
LCD. The variable resistor R2 is a contrast potentiometer. It is used to control the LCD contrast.

4.2.2
CapSense® Buttons (P3[0], P3[7]), and Sliders (Port5)
There are two CapSense buttons and eight element CapSense sliders on the CY3214PSoCEVALUSB kit. CapSense Sigma Delta uses an external modulation capacitor (CMOD), the
copper sensor pad on the CY3214 PSoCEVALUSB board, and bleed resistor (Rb) in addition to the
sensor capacitor (Cx).
Bleed Resistor (Rb): The CSD uses the switched capacitor circuitry to convert the sensor
capacitance into a voltage, which is compared to a reference voltage. When the capacitor voltage
reaches the reference voltage, the comparator triggers a bleed resistor discharging the capacitor.
After the capacitor voltage discharges below the reference voltage, the bleed resistor is left floating
to allow the capacitor to continue charging. The comparator output becomes a bit-stream as it
toggles the bleed resistor and manipulates its input voltage. This bit stream is ANDed with a pulse
width modulator (PWM) to provide consistent stream framing. The number of counts in each frame is
analyzed to determine if the capacitive sensor is activated.
Modulation Capacitor (CMOD): The capacitor CMOD acts to attenuate high-frequency noise. The
pin assignment for CapSense buttons used in the CapSense code example (see My First Code
Example on page 31) are as follows:
B2 – P3[7]
B3 – P3[0]
The slider segments pin assignment used in My First Code Example on page 31 are as follows:
Slider 0 – P5[7]
Slider 1 – P5[5]
Slider 2 – P5[3]
Slider 3 – P5[1]

The ICE-Cube (available in the CY3215-DK Kit) provides significant debugging functionality that
requires full two-way communication between the ICE and your computer. This software interface
allows to run, halt, and single-step the processor and view the content of specific memory locations.
It also allows to set complex event points. Event points can start and stop the trace memory on the
ICE, as well as break the program execution. The ICE-Cube supports large memory model PSoC
devices (with more than 256 bytes of RAM) and is backward compatible with previous PSoC devices
(CY8C27x43 and CY8C24x23A).

Project Description
This code example demonstrates the USB function using the CY3214-PSoCEVALUSB Kit. In this
project, the Buttons and Lights PC Host GUI is used to control the LEDs on board. The GUI also has
four soft buttons and four LEDs. When there is a button press event on the board, the board sends
out the buttons report to the GUI. The GUI updates the local LEDs and sends out a Lights report
back to the board. The LEDs on the board are updated based on this Lights report. The GUI also
provides the LED output as a logical function of soft buttons and buttons on board. The LED output is
a function of 'AND' or 'OR' of soft buttons and real buttons. By default, the LED output is that of real
buttons The following module is used in the project:

1. Program the board with Example3.hex from <Install_Directory>:\Cypress\CY3214PSoCEVALUSB\<version>\Firmware\Process Monitoring\PSoC Project\
Example3\, as explained in Programming Specifications and Connections on page 16.
2. On successful programming, disconnect the MiniProg1 and connect the board to the PC.
3. Wait until the HID device is installed (first time only) and run Example3.exe.
The LCD display shows the temperature value but indicates it is waiting for input from Host (PC).
4. Open the Process Monitoring GUI (Example3.exe) from
<Install_Directory>:\Cypress\CY3214-PSoCEVALUSB\<version>\Firmware\Process Monitoring\PC Software\Example3.
5. On the GUI, click the GetSamples button. The PC waits until 256 samples are received from the
board and then displays a graph of Temperature Vs Time.
6. Vary the VR1 on the board and click the GetSamples button again to see the difference in the
graph. This difference can be best viewed when Continuous Sampling is selected.
7. If continuous sampling is required, click the Continuous Samples button. The PC displays the
graph after every 256 samples received.
Note If the Sample Rate slider is kept at a minimum, the time taken to display graph also increases
as the graph is displayed only after receiving 256 samples.

Description
This project is used to control the mouse cursor movement using the joystick onboard. The joystick
movements are digitized using an ADC and the change in ADC values are used to decipher the
direction of movement.The USBFS module is used to enumerate as a mouse device and the mouse
is controlled based on the ADC value and direction of movement. The following user modules are
used in the project:
5.9.2
■
DUALADC: It is used to get the samples that will be used as reference values for horizontal and
vertical movement of the joystick. DUALADC is used to sample two input voltages simultaneously. Both the horizontal and vertical movements of the joystick are monitored simultaneously to
detect any minimal change in position of joystick.
■
LCD: It is used to display the message.
■
PGA: Two PGAs are used at unity gain to supply two inputs to DUALADC
■
USBFS: This module is used to transmit the data to control the mouse pointer based on the joystick movement.
Hardware Connection
■
