Pmod

只需一招,Zynq搭配Pmod开发,没驱动也不怕

之前我们提到过「Pmod传感模块」,这一搭配FPGA开发板进行快速原型系统开发的利器。事实上,除了Pmod标准定义接口的专利方 —— Digilent公司所提供的近百种功能丰富的原厂Pmod传感模块之外(一般都配有免费的ip驱动供开发者直接调用),市场上存在着很多来自不同供应商所提供的可用Pmod模块。

Avnet 为 Spartan®-6 LX9 FPGA MicroBoard 提供了 web 连接功能、伺服电机控制参考设计。 该设计不仅说明了为 MicroBoard 添加小型 Digilent Pmod 扩展模块的简便性,而且提供了优秀的代码实例,可以更加快速地对时序关键型硬件接口进行原型设计和测试。
The Web Connectivity Servo Control reference design demonstrates how you can use a standard web browser on a PC, tablet, or smart phone to control a servo motor and LEDs on a remote FPGA based system. Using the low-cost Spartan-6 LX9 MicroBoard, the reference design implements a MicroBlaze soft processor in the FPGA to run a web server. The MicroBlaze-based server connects to a remote PC or wireless hub via an Ethernet cable and allows users to control the servo position through a web browser based GUI. The GUI also provides remote control for the 4 LEDs on the MicroBoard as well as read-back status of 4 DIPs switches on the board. The FPGA design and server software included in the reference design provide an excellent starting point for any type of web-based data collection or control system.
