CP2400/1-DK
The wakeup frequency box calculates the period of a single iteration through the four power modes and displays
the system wake up frequency. This is typically the "sample rate" in low power analog sensors.
Once the battery type and discharge profile is specified, the user can click the "Simulate" button to start a new
simulation. The simulation engine calculates the estimated battery life when using one single-cell battery, two
single-cell batteries in series, and two single-cell batteries in parallel. Figure 7 shows the simulation output window.
Figure 7. Battery Life Estimator Utility Simulation Results Form
The primary outputs of the Battery Life Estimator are an estimated system operating time and a simulated graph of
battery voltage vs. time. Additional outputs include estimated battery capacity, average current, self-discharge
current, and the ability to export graph data to a comma delimited text file for plotting in an external graphing
application.
3.7. Keil µVision2 and µVision3 Silicon Laboratories Drivers
As an alternative to the Silicon Laboratories IDE, the µVision debug driver allows the Keil µVision2 and µVision3
IDEs to communicate with Silicon Laboratories’ on-chip debug logic. In-system Flash memory programming
integrated into the driver allows for rapid updating of target code. The µVision2 and µVision3 IDEs can be used to
start and stop program execution, set breakpoints, check variables, inspect and modify memory contents, and
single-step through programs running on the actual target hardware. For more information, refer to the µVision
driver documentation. The documentation and software are available on the kit CD and from the downloads
webpage: www.silabs.com/mcudownloads.
