Microchip has released the MPLAB Starter Kit for dsPIC digital signal controllers (DSCs), which comes with complete development software and hardware, including the USB-powered 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, 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). Additionally, the board has 4 Megabits of serial Flash memory to store audio messages and a 16-/24-/32-bit audio CODEC with sampling frequencies up to 48 kHz. The demo board also includes a 100 mW headphone amp, and microphone and line level inputs, along with a sample program for recording custom audio content.
