If you‚â€™re looking to quickly and inexpensively evaluate semiconductor architectures and high-speed applications such as DSCs and digital audio, this may be the kit for you. Microchip Technology Inc., makes adding digital audio to embedded designs easy with its MPLAB Starter Kit for dsPIC DSCs. It comes with complete development software and hardware, including the USB-powered Digital Signal Controller (DSC) board with integrated debugger and programmer, the MPLAB IDE and MPLAB C30 C complier software, and sample programs and hardware for demonstrating speech and audio applications.
The board is populated with a 40 MIPS dsPIC33FJ256GP506 DSC, which has 256 KB of Flash program memory and 16 KB of RAM, a 12-bit analog-to-digital converter (ADC), and peripherals that support audio pulse-width modulation (PWM). In addition, the board has 4 Mbits of serial Flash memory to store audio messages and a 16/24/32-bit audio CODEC with sampling frequencies to 48 kHz. The demo board also includes a 100 mW headphone amp, microphone and line level inputs, and a sample program for recording custom audio content.
