Page 6: Chapter 1: Stellaris® Lm3S818 Controlcard Module Overview
The Stellaris® LM3S818 controlCARD module is a DIMM form-factor module that can be used standalone or with a range of baseboards to accelerate evaluation and development. Texas Instruments offers a range of controlCARD baseboards for motor and power-control application. In most cases. these are available as complete kits that include a controlCARD module and a baseboard. -
Page 7: Compatibility Matrix
To start using the controlCARD module as a standalone module, see the MDL-LM3S818CNCD Read Me First document. To start using the controlCARD module in conjunction with a Texas Instruments’ controlCARD baseboard, see the Read Me First do November 17, 2011... -
Page 8: Chapter 2: Hardware Description
Hardware Description In addition to an LM3S818 microcontroller, the controlCARD module includes some simple multiplexing logic and an integrated Stellairs in-circuit debug interface (ICDI). This chapter describes how the hardware interfaces to the microcontroller. Figure 2-1 shows the controlCARD module block diagram. Figure 2-1. -
Page 9: Functional Description
Microcontroller and Interfaces (Schematic Page 2) LM3S818 Microcontroller The Stellaris LM3S818 is an ARM Cortex-M3-based microcontroller with 64-KB flash memory, 8- KB SRAM, 50-MHz operation, Motion control PWMs, and a wide range of other peripherals. Refer to the LM3S818 data sheet for complete device details. - Page 10 Hardware Description CCP2 31(DRV8301), CAP3 CAP3 36(DRV8312) CCP4 DAC_PWM1 DAC_PWM1 TRSTn TRSTn TRSTn U0Rx GPIO-28 (spare SCI Reset The RESET signal into the LM3S818 microcontroller connects to an R-C network (R1/C8) and to the ICDI circuit for a debugger-controlled reset. External reset is asserted (active low) under any one of these conditions: Power-on reset By the ICDI circuit when instructed by the debugger (this capability is optional, and may not be...

Stellaris® LM3S818 controlCARD Module User’s Manual Power Supplies The controlCARD module is typically powered by the baseboards via the DIMM edge connector. When used as a standalone module, without a baseboard, install wire jumpers to support USB-powered operation. WARNING – Do not install the wire power links if the controlCARD module is installed in a baseboard. -
Page 12: Figure 2-2. Controlcard Module Isolation
Hardware Description Figure 2-2. controlCARD Module Isolation The controlCARD module may be used without a baseboard. In order to power the non-isolated circuitry, power must be bridged across the isolation barrier as shown in Figure 2-3. November 17, 2011... -

Generic Gnu C compiler Texas Instruments' Code Composer Studio™ IDE Baseboards from Texas Instruments may not support all toolchain options. Evaluation versions of these tools may be downloaded from www.ti.com/stellaris. Due to code size restrictions, the evaluation tools may not build all example programs. A full license is necessary to re-build or debug all examples. -
Page 14: Programming The Mdl-Lm3S818Cncd Controlcard Module
Software Development Programming the MDL-LM3S818CNCD controlCARD Module The MDL-LM3S818CNCD software package includes pre-built binaries for each of the example applications. If you installed StellarisWare to the default installation path (C:\StellarisWare), you can find the example applications in "C:\StellarisWare\boards\mdl-lm3s818cncd". The on-board Stellaris ICDI is used along with the Stellaris LM Flash Programmer tool to program applications on the MDL-LM3S818CNCD board. -
