Page 15: Usb Functions
Stellaris® LM3S2965 Evaluation Board Two solutions exist. Some debugger interfaces (such as ULINK) have an internal power jumper that, in this case, should be set to internal +3.3-V power. Refer to debugger interface documentation for full details. However, if your debugger interface does not have a selectable power source, it may be necessary to install a 0-Ω... -
Page 16: Control Interface
Hardware Description Fast response 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. Stellaris® Firmware Development Package (included on the Documentation and Software CD) contains complete drivers with source-code for the OLED display. -
Page 17: Interfacing To The Evb
Using the In-Circuit Debugger Interface The Stellaris LM3S2965 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 14 for a description of how to enter Debug Out mode. -
