General Safety Instructions

ESD Protection

ESD can damage boards and associated components. Cypress recommends that the user perform
procedures only at an ESD workstation. If an ESD workstation is not available, use appropriate ESD
protection by wearing an antistatic wrist strap attached to the chassis ground (any unpainted metal
surface) on the board when handling parts.

Handling Boards

CY8CKIT-040 boards are sensitive to ESD. Hold the board only by its edges. After removing the
board from its box, place it on a grounded, static free surface. Use a conductive foam pad if
available. Do not slide the board over any surface.

The kit allows programming and debugging of the PSoC 4 device in two modes:

■ 3.3.1 Using the Onboard PSoC 5LP Programmer and Debugger

■ 3.3.2 Using the CY8CKIT-002 MiniProg3 Programmer and Debugger

3.3.1 Using the Onboard PSoC 5LP Programmer and Debugger

The default programming interface for the kit is a USB-based, onboard programming interface.
Before trying to program the device, PSoC Creator and PSoC Programmer must be installed. See

Install Software on page 15 for information on installing the kit software.

1. To program the device, plug the USB cable into the programming USB connector J10, as shown

in Figure 3-4. The kit will enumerate as a composite device. See Kit USB Connection on page 21
for details.

Kit Operation

2. The onboard PSoC 5LP uses serial wire debug (SWD) to program the PSoC 4 device. See

Figure 3-5.

Note: Figure 3-5 is provided only for reference, all connections are hardwired on the board itself.

Kit Operation

3. The kit’s onboard programmer will enumerate on the PC and in the software tools as KitProg.

Open an example project in PSoC Creator (such as Project: Blinking LED on page 54) and
initiate the build by choosing Build > Build Project or pressing [Shift] [F6]. See Figure 3-6.

Figure 3-6. Build Project in PSoC Creator

4. After the project is built without errors and warnings, choose Debug > Program or press

[Ctrl] [F5] to program the device. See Figure 3-7.

Figure 3-7. Program Device From PSoC Creator

The onboard programmer supports only the RESET programming mode. When using the onboard
programmer, the board can either be powered by the USB (VBUS) or by an external source such as
an Arduino shield (see Power Supply System on page 36). If the board is already powered from
another source, plugging in the USB programmer does not damage the board.

3.3.2 Using the CY8CKIT-002 MiniProg3 Programmer and Debugger

The PSoC 4 on the kit can also be programmed using a MiniProg3 (CY8CKIT-002). To use Mini­Prog3 for programming, use the J6 connector on the board, as shown in Figure 3-8. With MiniProg3,
programming is similar to the onboard programmer; however, it enumerates as MiniProg3 instead of
KitProg.

The board can also be powered from the MiniProg3. To do so, choose Tool > Options in PSoC Cre-
ator. In the Options window, expand Program/Debug > Port Configuration; click MiniProg3 and
select the settings shown in Figure 3-9. Choose Debug > Program to program and power the
board.

Figure 3-9. MiniProg3 Configuration in PSoC Creator

Note: Ensure that both MiniProg3 (with or without power) on header J6 and KitProg are not con­nected to the onboard PSoC 4 at the same time. This will result in failed device acquisition from
both.

3.4 USB-I2C Bridge

Kit Operation

The PSoC 5LP also functions as a USB-I2C bridge. The PSoC 4 communicates with the PSoC 5LP
using an I

2

C interface, and the PSoC 5LP transfers the data over the USB to the USB-I2C software

utility on the PC called the Bridge Control Panel (BCP).

The BCP is available as part of the PSoC Programmer installation. This software can be used to
send and receive USB-I
header J10 on the PSoC 4000 Pioneer Kit, the KitProg USB-I

2

C data from the PSoC 5LP. When the USB Mini-B cable is connected to

2

C is available under Connected I2C/

SPI/RX8 Ports in the BCP, as shown in Figure 3-10.

Figure 3-10. Bridge Control Panel

CY8CKIT-040 PSoC® 4000 Pioneer Kit Guide, Doc. # 001-91316 Rev. *F 25

Kit Operation

To use the USB-I2C functionality, select the KitProg USB-I2C in the BCP (Figure 3-10). On success­ful connection, the Connected and Powered status boxes turn green (Figure 3-11).

USB-I

C is implemented using the USB and I2C components of PSoC 5LP. The SCL (P12_0) and
SDA (P12_1) lines from the PSoC 5LP are connected to the SCL (P1_2) and SDA (P1_3) lines of
the PSoC 4 I

2

C. The USB-I2C bridge currently supports I2C speed of 50 kHz, 100 kHz, 400 kHz, and

1MHz.

See Using PSoC 5LP as a USB-I2C Bridge on page 105 for building a project that uses the USB-I

2

bridge functionality.

3.5 USB-UART Bridge

The onboard PSoC 5LP can also act as a USB-UART bridge to transfer and receive data from the
PSoC 4 device to the PC via the COM terminal software. When the USB Mini-B cable is connected
to J10 of the PSoC 4000 Pioneer Kit, a device named KitProg USB-UART is available under Ports
(COM & LPT) in the Device Manager. For more information about the USB-UART functionality, see

Using PSoC 5LP as a USB-UART Bridge on page 118.

Kit Operation

To use the USB-UART functionality in the COM terminal software, select the corresponding COM
port as the communication port for transferring data to and from the COM terminal software.

The UART lines from PSoC 5LP are brought to the P12[6] (J8_9) and P12[7] (J8_10) pins of header
J8. This interface can be used to send or receive data from any design/device that has a UART by
connecting the pins on header J8 to the RX and TX pins available on the connecting device.

Note: The PSoC 4000 family that is featured in the kit board does not support a full-duplex UART; it
can support only a software-based UART transmit on any pin. On the board, P3[0] of the PSoC 4000
device is hardwired to the UART bridge's RX line through zero-ohm resistor R57.

Ta bl e 3 -2 lists the specifications supported by the USB-UART bridge.
