并口模拟I^2C总线控制STV0299B+STB6000的软件设计

The Design of STV0299B + STB6000 Configuration Software through Parallel Port Simulating I^2C Bus

ST公司的STV0299B和STB6000构成的协同芯片组被广泛用于数字卫星电视高频头电路中。设计的软件通过在计算机并口模拟I2C总线通信,实现对STV0299B+STB6000的内部寄存器进行读写的功能,以测试和控制调谐器的工作状态。

The chipset of STV0299B and STB6000 are widely used in satellite DTV tuners. The software designed in this paper implements the function of reading and writing inner registers of STV0299B ＋ STB6000 through computer parallel port simulating I^2C bus, in order to test and control the working state of the tuner.
