摘要
为了采集望远镜指向信息及将跟踪数据及命令传送给伺服系统,对RSX-11M支持下的PDP-11/23计算机扩展了DRV11-J接口板。本文简单介绍同DRV11-J的通讯方法,中断、查询。特别详细介绍了用CINT＄指令写的驱动程序。
A DRV11-J interface board is connected to a PDP-11/23 computer under the support of the RSX-11M operating system in order to acquire the pointing information of a telescope and to transfer the tracking data and instructions to the scrvosystem. Three methods are introduced to access the interface, A driver which uses a CINT ＄ directive to connect an interrupt vector is introduced in more detail.
