Abstract: This article explains the recent trend in heart-rate and fitness monitors to go wireless toeliminate cables to allow free movement, and allow convenient data collection without the need to plug intheir devices. It details a typical wireless system, using the MAX1472 CRYSTAL-referenced phase-lockedloop (PLL) VHF/UHF transmitter.

ST7529液晶驱动 The ST7529 is a driver & controller LSI for 32 gray scale graphic dot-matrix liquid CRYSTAL display systems. It generates 255 Segment and 160 Common driver circuits. This chip is connected directly to a microprocessor, accepts Serial Peripheral Interface (SPI), 8-bit/16-bit parallel or IIC display data and stores in an on-chip display data RAM. It performs display data RAM read/write operation with no external operating clock to minimize power consumption. In addition, because it contains power supply circuits necessary to drive liquid CRYSTAL, it is possible to make a display system with the fewest components.
