The Microchip's DM330011 MPLAB Starter Kit for dsPIC Digital Signal Controllers is a complete hardware and software tool suite for exploring applications based upon Microchip’s dsPIC DSCs. With a built-in debugger on the board, simply install the software and connect the USB cable to the PC. Start up MPLAB IDE and you are in full control, able to run the sample programs, and to download and test your own applications.
The board is designed with dsPIC DSC with 256 KB of flash memory, a high-fidelity audio codec, microphone input and headphone/speaker outputs, and is powered from the USB connection to the PC. Also on the board are reconfigurable switches, potentiometers, a temperature sensor and a 4 Mb serial EEPROM to store data such as audio samples.
The Microchip's DM330011 MPLAB Starter Kit for dsPIC Digital Signal Controllers connects directly to a USB port on a computer. The PC USB connection supplies communications and power to the board. The starter kit includes debug and programmer circuitry that allows applications to be programmed onto the board’s dsPIC33FJ256GP506 device and then debugged, all using MPLAB IDE.
Audio input signals from an external microphone or audio equipment are routed to the ADC module in the on-board dsPIC33FJ256GP506 device for software processing. Alternatively, applications can use the audio codec for converting the audio signal.
The Output signals can be generated by the dsPIC33FJ256GP506 device’s Output Compare module as a pulse-width modulated digital waveform. This pulse-width modulated signal is converted to an analog signal by a low-pass filter on the starter kit board. Alternatively, applications can output audio data using the audio codec. The output audio signal is then amplified using a headphone amplifier circuit for playback on an output device.
