【摘要】 论述了一种基于U SB总线的全自动膜片钳系统数据接口。系统的主控芯片为CY 2131QC(Cypress),逻辑控制芯片为EPM 3256A(A ltera)。接口与前端系统之间采用光电隔离。由于使用了U SB总线,从根本上简化了现场安装工作。接口传输速率达到1 M bytes/s,符合新一代的全自动膜片钳系统数据采集和控制的要求。更多还原

【Abstract】 A USB bus based data interface technology for full auto Patch-Clamp system is discussed in the article.The main controller is CY2131QC(Cypress) and the logic controller is EPM3256A(Altera).Optocouplers are used to get rid of the noise from the interface.It makes the installation of the Patch-Clamp system easier by using the USB bus,and is suitable for the new generation of the Patch-Clamp system with a high speed of 1M bytes/s.更多还原
