4 Connecting CC2511 Dongle to SmartRF04EB.

Please see the “CC2430DK_CC2510_CC1110_User_Manual” for more information on the

SmartRF04EB and how to use the CC2510EM.

Make sure to install SmartRF®Studio before connecting the SmartRF04EB to a PC.

SmartRF®Studio can be downloaded from the www.chipcon.com or www.ti.com/lpw

The CC2511 have a 2 wire debug interface that is used for chip programming and debugging.

When connecting this interface to the SmartRF04EB USB MCU, the CC2511 can be

programmed from the Chipcon Flash Programmer software and debugged from IAR

embedded workbench..To connect the CC2511 Dongle to the SmartRF04EB follow these 6

steps:

1. Turn off the SmartRF04EB power by moving the power switch to the left position. See

Figure 3.

2. Remove any CCxxxxEM modules attached to the SmarRF04EB.

3. Connect the SmartRF04EB to a PC with the supplied USB cable.

4. Connect the CC2511 Dongle to the SmartRF04EB with the supplied 10 pin cable.

The cable should be mounted between the “SoC debug” connector on the CC2511

Dongle and the “P14 SoC debug / flash” connector on the SmartRF04EB. Make sure

pin 1 is connected to pin 1. This cable connects the debug interface and GND

between the two devices, however the CC2511 Dongle is not powered trough this

cable.

5. Power the CC2511 Dongle.

To power the CC2511 Dongle there are two options:

•Powered with a USB cable.

Using the supplied USB extension cable to connect the CC2511 Dongle to the

PC.

See Figure 1.

•Powered from the SmartRF04EB.

Connect pin 9 on the “Test pin” connector on CC2511 Dongle to pin 5 on the “I/O

A” connector on SmartRF04EB to power the Dongle from the SmartRF04EB.

See Figure 2.

The CC2511 Dongle should only be powered by one of the two sources at a time.

Do not connect the USB cable to the CC2511 Dongle while it is powered from the

SmartRF04EB.

The SmartRF04EB have a level converter on the debug connector, so the

SmartRF04EB and the CC2511 Dongle may have a different power supply voltage.

Figure 3: SmartRF04EB Power switch, power on.

The CC2511 can now be programmed with the Chipcon Flash Programmer software. The

firmware on the CC2511 can also be debugged using the IAR embedded workbench

debugger.

Please see the IAR user manual and the Chipcon Flash Programmer user manual for more

details.

5 Using SmartRF04EB as an In-Circuit Emulator (ICE)

The SmartRF04EB can be used as ICE for the CC2511

To use the SmartRF04EB as ICE, the IAR Embedded Workbench software must be installed.

The Embedded Workbench is a C-Compiler, Simulator, and ICE debugger. See the IAR

Embedded Workbench documentation supplied with the kit for instructions how to set up the

ICE debugger for use as an ICE.

When the SmartRF04EB is connected to a PC with the USB port, the debugger will connect

to the SmartRF04EB. Several SmartRF04EB can be connected to USB ports simultaneously.

A selection window will display the connected SmartRF04EB, and the user can select which

device to load.

For custom PCB’s with the CC2511, it is recommended to include a pin header or test points

to allow in-circuit emulation or programming using SmartRF04EB or other 3rd party

programming tools. Use the CC2511 Dongle as a reference. Please see the

CC2510/CC2511section of the Chipcon web site for an updated list of 3rd party programming

tools.

When using smartRF04EB as emulator for external target debugging any CCxxxxEM module

must be removed

The pin-out used on the SmartRF04EB is explained in Table 1 and Figure 4. The connector

includes 4 SPI control signals. These are currently not used, but they are included to give

users flexibility.

Table 1: P14 SOC debug connector pin-out

VDD note: The SmartRF04EB includes a voltage converter to support programming and

debugging of external systems with different voltage than the SmartRF04EB. The debug

connector includes two VDD connections on pin 2 and pin 9. The function is different for these

connections.

Pin 2 VDD supplies voltage to the voltage converter. If the target application is self powered

pin 2 should be connected to VDD to assure that the correct supply voltage is used for the

voltage converter. This pin must always be connected to VDD.

Pin 9 VDD supplies 3.3V from the SmartRF04EB. If the target application is powered from the

SmartRF04EB supply during programming and debugging this pin can be connected to VDD.

If the target voltage differs from 3.3V, this pin should not be connected.

On the CC2511 Dongle this pin is not connected. Hence the CC2511 Dongle must be

powered from a separate USB cable or a separate cable connecting pin 9 on “test pins” / P4

to VDD on the SmartRF04EB. See chapter 4 for details.

5.1 Debugging USB firmware

When writing and debugging USB firmware one should remember that when Windows (or

another OS) detects a USB device it will assume that it works in accordance with the USB

specification. During debugging this might not be the case. Breakpoints may stop the

execution of code on the CC2511 Dongle and firmware under development may not be

completed or error free. This may lead to the PC disconnecting the CC2511 Dongle and

turning off or toggling its power supply. In some cases Windows (or the OS in use) may crash

or misbehave. Hence breakpoints should be used with caution.

Obviously inserting and using breakpoints in the firmware during debugging will be extremely

useful to pinpoint bugs and follow code execution. And they can and should be used. But they

will also stop the code execution on the CC2511 and may cause the device to act in conflict

with the USB specification. This can lead to the PC disconnecting the CC2511 Dongle,

sending a USB reset or worst case the operating system may crash.

If the firmware contain bugs that make the PC disconnect the CC2511 Dongle it may be

necessary to disconnect the USB cable, and power the CC2511 Dongle from the

SmartRF04EB in order to reprogram it.

5.2 Known problems

When using the debug interface through the level-converter on the SmartRf04EB. (Shown in

Figure 1 and Figure 2) it might become unstable. This problem is more likely to occur a low

voltages or with crosstalk in the cable at high interface speed.

First make sure that the 10 pin flat cable used to connect the CC2511 USB Dongle to the

SmartRF04EB is as short as possible.

Next it might be necessary to reduce the debug interface speed in order to achieve stable

operation.

In the IAR workbench do the following:

•Highlight the project name by clicking on it in the “Files” window. (See Figure 6)

•Go to Project -> Options…

•Select the Category “Chipcon”

•Click on the “Target” tab.

•Check the “Reduce interface speed” option. (See Figure 7)

6 CC2511 application examples

This section describes the application examples available for the CC2511. These application

examples focus on how to use the USB on the CC2511. The examples is available both as

source code and ready-to-upload .hex files from the Chipcon website.

There are three CC2511 application examples.

•Wireless mouse / practical joke. (HID , Human Interface Devices)

•Wireless USB to Serial port converter. (CDC, Communication Devices)

•Wireless WinAmp remote control. (Vendor requests, custom Windows driver)

There is also a CC2510 Application Example available. This example provides valuable

information about setup and usage of different modules found in both CC2510 and CC2511.

Please see the “CC2430DK_CC2510_CC1110_User_Manual” for more information about this

Application Example.

All the application examples use the same packet format and radio frequency. This is done to

make it simple to observe the radio activity on the Chipcon General Packet Sniffer. After

installing the packet sniffer choose the “CC2511 App. Example protocol” to see the radio

traffic. Figure 8 show the packet sniffer observing radio traffic in the “Wireless USB to Serial

port converter” application example.

See the Chipcon General Packet Sniffer user manual for more information.

6.1 Wireless mouse / practical joke

This application demonstrates the use of the CC2511Dongle as a USB composite HID

(Human Interface Device), with both keyboard and mouse.

The application will work on most operating systems.

This application example uses the USB framework found in the CC2511 firmware library to

setup the USB on the CC2511 Dongle and to handle all USB standard requests. In addition

the Class requests required by the HID device class are implemented in a separate file.

The radio communication between CC2510EM and CC2511 Dongle is done using the RF part

of the CC2511 firmware library.

See “Device Class Definition for Human Interface Devices (HID)” found on

http://www.usb.org/developers/devclass_docs/HID1_11.pdf for more information about the

HID class.

6.1.1 Software components

•simple_hid_dongle.hex

The CC2511 USB Dongle firmware, is found in

”CC2511DK\embedded_sw\App_Ex\simple_hid\simple_hid_dongle\”.

•simple_hid_eb.hex

The CC2510 EM firmware is found in

”CC2511DK\embedded_sw\App_Ex\simple_hid\simple_hid_eb\”.

6.1.2 Installing the application

1. Attach the CC2510EM to a SmartRF04EB and program it with the flash image

simple_hid_eb.hex, using IAR workbench or the Chipcon FLASH programmer.

(See “CC2430DK_CC2510_CC1110_User_Manual” for more information).

2. Connect the CC2511 Dongle to the other SmartRF04EB and program it with the flash

image simple_hid_dongle.hex, using IAR workbench or the Chipcon FLASH

programmer.

(See “CC2430DK_CC2510_CC1110_User_Manual” for more information).

6.1.3 Running the application

Insert the CC2511 Dongle into a free USB port. The firmware will identify the CC2511 Dongle

as a composite HID with a keyboard and mouse.

On most operating systems no extra driver is necessary; the OS will automatically load a

standard driver for HID devices.

The pot-meter “RT1” on the SmartRF04EB is used to choose between the “simple mouse”

and the “practical joke” mode. Turn the pot-meter fully counter clockwise to select the “simple

mouse”, fully clockwise to select the “practical joke” mode.

In “simple mouse” mode the joystick on the SmartRF04EB can be used as a mouse. The

button “S1” is the left mouse button, pushing the joystick is the right mouse button.

While in simple mouse mode the CC2510 will calculate the RSSI (Receive Signal Strength

Indicator) on the packets received from the CC2511 Dongle and display it on the LCD screen.

The RSSI value is updated each second.

In “practical joke” mode there are three jokes to choose from:

•Moving mouse – the mouse will constantly move slowly towards the right.

•Write to screen – Writes the text “anybody home” to the PC.

•Change window (ALT – TAB) – Changes the active window in Windows by sending

the ALT – TAB keystrokes.

Move the joystick up and down to select joke, push “S1” button to start/stop.
