Design of Custom High-speed Serial Peripheral Interface in Multiple FPGA System 多FPGA系统中自定义高速串行数据接口设计
On this basis the completion of the Ethernet port, serial peripheral interface, such as the design and preparation of the driver was successfully integrated with the minimum system constituted in one hardware system. 在此基础上完成了以太网口,串口等外围接口的设计,并为之编写了驱动程序成功与最小系统构成完整的硬件系统。
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)。
