TMS320C6745 DSP Development Board

The TMS320C6745 DSP Development Board is specially desgined for developers in dsp field as well as beginners. The kit is designed in such way that all the possible features of the DSP will be easily used by the everyone.

The kit supports in Code Composer Studio3.1 and later, with XDS100 v1 USB Emulator which is done USB port.

LED’s

A Light Emitting Diodes (LEDs) are the most commonly used components, usually for displaying pin’s digital states.

Interfacing LED with TMS320C6745

The TMS320C6745 EVB board has twelve LED Connected with Dsp I/O pins (details tabulated below). The cathode of each LED connects to ground and Anode of each LED connects port via 180Ω resistor. To light an individual LED, drive the associated port signal to High.
