6.2.3. Interacting with the Windows SMBus Test Software
The TC-RTC Evaluation Board with the SMBus firmware enables an SMBus/I
test this interface, PC software is provided that emulates an SMBus master via the PC’s parallel port.
1. The PC Software is installed as part of the TC-RTC RD installation from the Reference Design Kit CD. Launch
2. Make sure that the green LED is blinking on the board, and then click the “Refresh All” button. This updates all
3. Modify any value(s) that you would like to modify, and click the corresponding “Write”, “Write NVRAM”, or “Write
4. Clicking the “Read” button will read the current values from the board.
5. Check the “Auto-refresh Time/Date” check box to automatically update values every second. Note that when
This PC software is provided solely for test and demonstration purposes. In a real application, the ‘F300 device
with the TC-RTC firmware is meant to be connected to other microcontrollers that have an SMBus interface. Refer
to "AN293: Temperature Compensated Real Time Clock Reference Design Programmer's Guide" for more details
on the SMBus interface implementation.
