通过SPI测试PLL器件 [英] Testing PLL device through SPI

问题描述

我需要为器件PLL（锁相环）编程外设测试代码，该代码通过SPI接口连接到FPGA。我们可以通过cpu（mpc83xx）以间接访问模式访问PLL设备。任何人都可以告诉我如何用c编程来测试PLL器件。我知道硬件部分和编程新手。请帮帮我。

Hi,
I need to program a peripheral test code for the device PLL(Phase locked loop)which is connected to the FPGA through the SPI interface. we can access the PLL device through cpu (mpc83xx)in indirect access mode. Can anyone tell me how to program in c for testing the PLL device. i know the hardware part and new to programming. Please help me out.

推荐答案

这是一项非常具体的任务，我怀疑我们可以提供帮助（至少没有进一步的细节）。如果您知道如何测试 PLL 和 SPI 协议，那么您只需要学习 C 编程语言。这是一个相对简单的任务：您可以在网上找到许多教程（您可能会发现 SPI 通信示例代码）。

That''s a very specific task, I doubt we could be helpful (at least without further details). If you know how to test the PLL and the SPI protocol then you just need to learn the C programming language. That''s a relatively simple task: you may find many tutorials on the web (you may find SPI communication sample code as well).
