Development platform Texas Instruments DK-LM3S-DRV8312

Detailed Description

The low-cost Stellaris LM3S818 microcontroller (MCU) on the MDL-LM3S818CNCD controlCARD module comes pre-programmed with the necessary firmware in flash memory to run the Texas Instruments' (TI) InstaSPIN™ BLDC motor control solution out-of-the-box once plugged into the DRV8312 baseboard. The system will automatically detect and spin a customer’s 3-phase brushless DC motor.

The operation of this system is controllable and viewable across a USB interface using an included Crosshairs-enabled GUI environment that consists of a PC application interface and Crosshairs’ embedded kernel running on the LM3S818 MCU. The LM3S818 MCU provides all of the necessary computational requirements to run TI’s InstaSPIN BLDC technology and other customer-developed applications as well.

Follow the steps in the kit's README First document to quickly get up and running. Using TI’s InstaSPIN BLDC technology, you can quickly identify a 3-phase brushless motor’s key characteristics in order to spin the motor successfully.

Features

The DK-LM3S-DRV8312 motor control kit contains a cost-effective, Stellaris LM3S818 MCU-based controlCARD module compatible with other TI motor control platforms.

In addition to instantly spinning your motor, the kit also demonstrates the InstaSPIN BLDC motor control solution's operational advantages with simplified tuning, immediate acceleration adaptation, reliable low-speed operation, and more.

The included Crosshairs solution enables users to control and monitor the total solution through an easy-to-use PC application that can be extended for customer applications.
