AC164125接口板主要属性是用于语音存储的板载 250 Kbit SPI 串行 EEPROM。它主要用于音频,语音录制/回放。The Speech Playback PICtail Plus Daughter Board is designed to allow a customer to evaluate and develop speech recording and playback applications using Adaptive Differential Pulse Code Modulation (ADPCM). The daughter board is designed to interface with both the PICtail interface used on many PIC16 and PIC18 evaluation boards and the PICtail Plus card edge connector used on PIC24 and dsPIC evaluation boards. Users can reference AN643 for information on implementing an ADPCM solution. This product is also part of the HumanInterface Program.
