In this setup, the user can incorporate the debugging capabilities into the final application using a cheap 4-pin

header connection.

2. Debugging an Application

To debug an application the user is provided with the Silicon Laboratories IDE (Integrated Development

Environment). The IDE has an integral help. This section is not a user manual for the IDE, but highlights the items

which are important when working with the IDE.

2.1. Installing the IDE and USB Debug Adapters

Download the Silicon Labs IDE (Integrated Dvelopment Environment) from the following URL:

http://www.silabs.com/products/mcu/Pages/SiliconLaboratoriesIDE.aspx and install it on your computer. The IDE

gets installed into its own directory. The main executable file is IDE.exe. The IDE works with the USB Debug

Adapter or the Toolstick Base Adapter, shown in the section above. When the IDE recognizes the Silicon Labs USB

debug adapters, it queries whether its internal firmware is compatible with the Si4010. If not, then it notifies the user

and requests permission to update the adapter's firmware. Silicon Labs also provides a program,

usb_debug_adapter_firmware_reset.exe

, to clear the adapter's firmware manually before connection to

the IDE. The program resides in the same directory as the IDE main executable.

With the Si4010 debugging chain it is required that the manual adapter firmware clearing is done for each USB

adapter before using the key fob debugging chain. That operation needs to be done only once per USB Debug

Adapter. The IDE will then program the correct firmware into the adapter.

The reset firmware executable will scan USB ports and give the user a list of connected Silicon Labs USB

adapters. The USB Debug Adapter name starts with EC. Users can have more than one USB adapter connected

to the computer.

2.2. Keil toolchain integration

The project files in examples assume that the Keil toolchain is installed into: C:\Keil directory. The location of

the Keil toolchain can be easily changed in the Silabs IDE in the Project—Tool Chain Integration menu. An

version has a 2 kB code limitation and starts the code at the 0x0800 address. The Keil free evaluation version can

be unlocked to become a 4 kB version with no code placement limitation by following the directions given in

application note AN104 about Keil toolchain integration and license management. Unlock code can be found on

the WDS CDROM in the root folder in the Keil_license_number.txt file. Contact your Silicon Laboratories sales

representative or distributor for application assistance.
