Fan Speed Control with the EMC2102 Device

5 Basic Operation Experiments

In this chapter basic operation experiments will be provided to help users to get familiar with the system.

5.1Experiment 1 - Manual Fan Control

This experiment is designed to gain familiarity with both the EMC2102 device, and the application software, ChipMan.

The ChipMan application can be used to configure the EMC2102 device and to monitor the status of the device. It includes tools to capture and plot data at rates up to 10Hz. Additionally, ChipMan can be used to review previously saved data.

5.1.1ChipMan Installation

Install the ChipMan application and device driver on a PC by running Setup.exe from the EMC2102 Evaluation System Software CD provided by SMSC. A revision history and install/uninstall notes may be found in the readme.txt file on the disk.

ChipMan uses definition files and data files to identify the devices it supports, to load specific values into registers, and monitor, plot, or record the values of any register set in the device. ChipMan definition files are XML files conforming to XML Version="1.0" and Encoding="utf-8". The data files for downloading values to the device are CMF files, specific to the ChipMan application.

The CMF files may be located anywhere on the hard drive, but the XML files MUST reside in the ChipMan directory, typically located at: C:\Program Files\SMSC\ChipMan\Chips. An XML file usually names with the device name that supports (EMC2102.xml, EMC2103-2.xml, etc.)

During the installation of the ChipMan application, it is possible to specify a non-default installation directory. If this was done, substitute the path provided at that installation for "C:\Program Files" to store the XML files in the proper location.

Connect the USB cable to an available USB port on the PC, (The other end, “mini-B” end, of the USB cable should be connected to an EMC Evaluation Board). The “Find New Hardware” wizard will pop up on the PC’s screen for USB driver installation. Follow the instructions on the screen to complete the installation process.

5.1.2Setting Up the ChipMan

Once the ChipMan has been installed, start the software by selecting Start -> Programs -> SMSC -> Chip Manager. If this is the first operation, the application will guide you to select a device, as shown in Figure 5.1 below.

Figure 5.1 ChipMan Message for First Operation

Answer "Yes", then the device selection menu as shown in Figure 5.2, "ChipMan Device Selection Window" will appear.

Click on the Pull-Down menu at the top, select EMC2102 as shown in Figure 5.3, "Selecting the Device and Master Controller Type", and click OK. The ChipMan operation window will then appear, as shown
