Design of Interface and Communication for SAR Imaging Signal Processor SAR成像信号处理机的接口与通信设计
After the serial peripheral interface ( SPI) was used to implement communication of Arm processor with CAN controller. CAN-Bus driver program and application program in Arm-Linux embedded system were designed, and the graphical user interface ( GUI) based on Arm-Linux was developed. Arm处理器以同步外设接口(SPI)方式与CAN控制器相通信,开发了Arm-Linux嵌入式系统下的CAN-Bus驱动及应用程序,且设计了嵌入式环境下图形界面系统(GUI)。
Communication interface between PC and CAN card is realized by VB. This article introduces communication data process of CAN model in single chip processor ( F040). 上位机与CAN卡的接口采用VB编写,本文还给出了单片机中CAN模块通信的数据处理方法。
Computer interface technology is the key technology of It plays a communication peripheral device with the central processor bridge. 而接口技术在其中起着沟通外围设备与中央处理器的桥梁作用。
