3.1 Hardware and Software Requirements

The following hardware (HW) equipment and software (SW) are required to allow full evaluation of the TIDA-010072 reference design.

Table 3-1 Hardware and Software Requirements
HW AND SW COMMENTS
6-28 V, 10-A adjustable power supply Required current capability depends on load under test
TIDA-010072 Design Folder
LAUNCHXL-F28027F & USB cable

Tool Folder
MSP-FET Tool Folder
CCS 10.0.0 or newer Download Link
Motorware 1.01.00.18 Download Link
DRV832x Firmware (InstaSpin) Download Link

Alternatively, the user can use LAUNCHXL-F280049C or LAUNCHXL-F28069M. However, motorware may not have solutions available for DRV8323 specifically. The user may need to port some FW.

Tip:

The MSP-FET is required only if the user intends to evaluate the DRV8847 solenoid drivers and the TMP1075 temperature sensors. CCS provides the user interface to control the valve drivers and readout the temperature. The BLDC motor control can be evaluated independent of the MSP430 functions.
