To get started with development, download and extract the Audio Development Board compressed Audio Development Board Information Sheet archive file from www.microchip.com/adb. Connect a debugger or programmer such as the MPLAB REAL ICE In-Circuit Emulator or ICD 3 to the RJ-45 (J3) connector. Open MPLAB and Features load the ADB Demo workspace. Compile, program and run the demo. For more information on the hardware, refer to the Audio Development Board Users Guide (DS70662). The Audio Development Board is a high quality audio development platform using a 16-bit or 32- bit microcontroller (MCU). The on-board high-performance MCU is ideal for complex audio algorithms, which are computation intensive. Features of the Audio Development Board are: High-performance microcontroller Wolfson WM8960 audio codec with up to 48 kHz sampling rate and up to 24-bit resolution, headphone out and line-in jacks, and an on-board microphone TFT Color Display with 220x176 resolution USB and UART communication interfaces PICtail Plus expansion connector for Made for iPod Getting Started The Audio Development Board is preprogrammed with an audio demonstration. Use the following procedure to run this demonstration: 1. Power the ADB by connecting the 9V power brick provided with the ADB in the power connector (J1). Americas Asia/Pacific (Continued) 2. Connect a pair of headphones or powered speakers into the jack labeled HP OUT (J6). Atlanta - 678-957-9614 China - Chongqing - 86-23-8980-9588 3. A line-in input to the Line IN (J5) jack can be connected or the on-board microphone (MIC) can Boston - 774-760-0087 China - Hangzhou - 86-571-2819-3180 be used for audio input.
