EVM Overview www.ti.com 1 EVM Overview 1.
Hardware Interfaces 2.2 www.ti.com Resolver Interface Pinout The AMC1210MB-EVM is designed for easy interfacing to resolver applications. Connector J5 is a nine-pin, female-type DSUB connector for connection to a standard resolver. To hold the floating resolver inputs to a predefined common-mode level, a 2.5-V offset is added to the resolver inputs. The AMC1210MB-EVM resolver interface pinout is detailed in Table 2. Table 2. AMC1210MB-EVM Resolver Interface Pinout 2.
Hardware Interfaces www.ti.com 2.4 Jumpers JP1 and JP2 are available to configure the resolver carrier signal driver. The carrier signal may either be driven directly by the AMC1210 or through the OPA1632 operational amplifier. The purpose of the OPA1632 is to provide the ability to filter the carrier signal and continue to be capable of sourcing 85 mA on the carrier. This interface is shown in Table 4. Table 4. AMC1210MB-EVM JP1 and JP2 Interface Jumper 2.
Software 3 www.ti.com Software The program for evaluating the AMC1210MB-EVM is the AMC1210EVM software. This program uses the NI-VISA™ client to communicate with the hardware through a USB port. The program currently runs only on PCs with the Microsoft Windows XP operating system. Windows Vista and Windows 7 are not supported. 3.1 Installation Follow these procedures to install the AMC1210MB-EVM software. Step 1. Install the AMC1210MB-EVM software and LabVIEW™ RunTime Engine software.

Software www.ti.com Figure 4. NI-VISA AMC1210MB-EVM Driver Installing Figure 5.
Software www.ti.com Step 3. Verify that installation is completed correctly by opening the Windows Device Manager and locating the driver, as shown in Figure 6. Figure 6. NI-VISA AMC1210MB-EVM Driver Verification 3.2 Using the AMC1210MB-EVM Evaluation Software The AMC1210MB-EVM evaluation software provides two modes of operation: Resolver Demo and Current Shunt. Each mode of operation provides a separate GUI and features for evaluating the AMC1210.
Software www.ti.com The toolbar shown in Figure 8 is present, regardless of the mode of operation of the AMC1210MB-EVM software. The left-most button is used to switch between Current-Shunt Mode and Resolver Demo Mode. The remaining buttons are provided for convenience to quickly access information about the device or visit the TI E2E community for support or device queries. Figure 8.
Software www.ti.com Each filter module also has an enable or disable control located below the register configuration indicators. Only enabled filter modules data are displayed in the Current Shunt Data tab. Figure 10 shows an sample set of collected data in the Current Shunt Data tab, with module 1 enabled and module 2 disabled. The Current Shunt Data tab displays collected data in terms of raw codes instead of voltage because a variety of delta-sigma modulators may be connected to the AMC1210.
