Abstract: Principles of the transfer interface and the transmitreceive process of voice data are depicted. Using CC2430 as the core processor, the data acquisition system is extended by adding the TLV320AIC1107 PCM codec to perform the transmitreceive encoding conversion with baud rate at 64kbps. Tests show some features of the design, such as less additional peripheral devices, short latency, and low consumption.
