(VCP) transmit channel. The debugger can then decode and interpret the trace information received from the VCP. The normal VCP connection to UART0 is interrupted when using SWO. Not all debuggers support SWO. Refer to the Stellaris LM3S6965 data sheet for additional information on the trace port interface unit (TPIU). -
Page 14: Control Interface
Hardware Description Control Interface The OLED display has a built-in controller IC with synchronous serial and parallel interfaces. Synchronous serial (SSI) is used on the EVB as it requires fewer microcontroller pins. Data cannot be read from the OLED controller; only one data line is necessary. Note that the SSI port is shared with the microSD card slot. -
Page 15: User Led
Stellaris® LM3S6965 Evaluation Board User LED A user LED (LED3) is provided for general use. The LED is connected to PC5/CCP1, allowing the option of either GPIO or PWM control (brightness control). Refer to the Quickstart Application source code for an example of PWM control. Bypassing Peripherals Excluding Ethernet, the EVB’s on-board peripheral circuits require 16 GPIO lines. -
Page 16: Using The In-Circuit Debugger Interface
Using the In-Circuit Debugger Interface The Stellaris LM3S6965 Evaluation Kit can operate as an In-Circuit Debugger Interface (ICDI). ICDI acts as a USB to the JTAG/SWD adaptor, allowing debugging of any external target board that uses a Stellaris microcontroller. See “Debugging Modes” on page 12 for a description of how to enter Debug Out mode. -

Stellaris® LM3S6965 Evaluation Kit Note: In Table B-2, an asterisk (*) by a signal name (also on the EVB PCB) indicates the signal is normally used for on-board functions. Normally, you should cut the associated jumper (JP1-15) before using an assigned signal for external interfacing. Table B-1. -
Page 26: Arm Target Pinout
ARM Target Pinout ARM Target Pinout In ICDI input and output mode, the Stellaris LM3S6965 Evaluation Kit supports ARM’s standard 20-pin JTAG/SWD configuration. The same pin configuration can be used for debugging over Serial Wire Debug (SWD) and JTAG interfaces. The debugger software, running on the PC, determines which interface protocol is used. - Page 27 – RealView MDK web site, www.keil.com/arm/rvmdkkit.asp – IAR Embedded Workbench web site, www.iar.com – Code Sourcery GCC development tools web site, www.codesourcery.com/gnu_toolchains/arm – Code Red Technologies development tools web site, www.code-red-tech.com – Texas Instruments’ Code Composer Studio™ IDE web site, www.ti.com/ccs January 6, 2010...
