The MPLAB Starter Kit for dsPIC Digital Signal Controllers connects directly to the USB port on a PC. The USB connection supplies both communications and power to the board. The starter kit includes debug and programmer circuitry that allows applications to be programmed onto the board’s dsPIC33 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 dsPIC33 device for software processing. Alternatively, applications can use the audio codec for converting the audio signal. Output signals can be generated by the dsPIC33 device’s Output Compare module as a pulse-width modulated (PWM) digital waveform. This PWM signal is converted to an analogue 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.
