6. Reference Design Documentation and Source Code
The architecture of the Voice Recorder Reference Design is described in detail in the application note AN278,
which is included on the Kit’s CD-ROM. AN278 includes the Voice Recorder board schematic, bill of materials
(BOM), and C-language firmware source code.
To debug and download code to the Voice Recorder, the Keil C51 tools (compiler, linker, and assembler) and Sili-
con Labs USB Debug Adapter are required. These can be purchased separately from the Silicon Laboratories
website or as part of the C8051F410DK Development Kit (which includes the evaluation version of the Keil C51
tools). For more information, please visit the “Development Tools” webpage or contact the local Silicon Laborato-
ries distributor.

The Silicon Laboratories Integrated Development Environment (IDE) can be used with the USB Debug Adapter to
program and develop on the reference design boards. The Silicon Labs IDE and other software tools can be down-
loaded from the following link:

7. Debugging with the Voice Recorder
To debug and run the Voice Recorder firmware in the Silicon Labs IDE, first disconnect the power to the Voice
Recorder board. Then, connect the USB Debug Adapter (not included in the Voice Recorder kit) and reconnect the
power, as shown in Figure 4.
Connect the USB Debug Adapter (UDA) to the PC and open the Silicon Laboratories IDE. The Voice Recorder
project can be opened by going to ProjectOpen Project and selecting “F411_VR.wsp” after navigating to the
proper directory.
