摘要
EZ-USB FX2支持全速(12 Mbit/s)和高速(480 Mbit/s)设备,是新一代的通用串行总线标准。它有3种接口模式,即端口模式、GPIF控制器模式和从属FIFO模式。采用GPIF控制器模式,直接与A/D转换器TLV1578相连,实验证明该方法是可行的。
Cypress＇s EZ-USB FX2 is the world＇s first USB 2. 0 integrated microcontroller, which supports device of high speed （480 Mbit/s） and full speed （12 Mbit/s）,and it is a new generation of the standard peripheral interface bus. Three modes are available. Port, GPIF master, and Slave FIFO. GPIF master is used in this paper. It connects TLV1578 dirrectly. It can improve efficiently the performance in data sampiing in practice.
