Abstract: Principles of the transfer interface and the transmitreceive 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 transmitreceive 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.
Key words: zigbee, data acquisition, wireless SCM
