您好,我正尝试将CyPress SL811HST AXC USB主机/从控制器与Altera Curror I FPGA接口,CypLSS芯片没有响应我的信号,我尝试通过驱动控制线来写入一个8位数据到芯片的随机地址,对应于提供的时序图。D用芯片数据表,然后在相同的地址读取,但没有成功,当我尝试通过把输出放在高阻抗状态“Z”中读取数据时,我得到了我放在8位线上的地址,所以CyPress没有响应我的命令,所以如果有人感兴趣,或者有一个类似的问题,给我你的想法或任何可能的解决办法,谢谢!!
以上来自于百度翻译 以下为原文 Hi, I am trying to interface a Cypress sl811hst-axc u*** host / slave controller with an Altera Cyclone I FPGA, the cyperss chip isn't responding to my signals, I've tried to write an 8bit data to a random address of the chip by driving the controls lines, corresponding to the timing diagram provided with the chip datasheet, and then read at the same address, but with no success, when I try to read a data by putting the output in a high impedence state "Z", I get the address that I've put on the 8 bit lines, so the cypress is not responding to my commands so if anyone is interested, or had a similar problem, give me your ideas or any thought about a possible solution thanks !! |

嗨,谢谢你的快速回答,我已经附上了我的项目文件T的消息,所以你可以有更多的信息,我必须精确地说,我试图与芯片互动,好像它是一个简单的256字节的内存,我甚至没有插入USB驱动器,只是做一个基本操作令状在一个内存地址和读取存储在那里,我选择的MeMro位置和价值,我想写的组合开关,然后我在同一位置阅读,并显示在LED,感谢您对我的问题感兴趣!
方块图 76.8 K 以上来自于百度翻译 以下为原文 hi, thank you for your quick answer, i've attached my project files t othe message so you can have more information, i have to precise that I am sort of trying to interact with the chip as if it was a simple 256 bytes memory, I don't even plug a USB drive to it, just doing a basic operation of writing to a memory address and reading back what is stored there, I choose the memro location and the value I want to write with a combination of switch, then I read at the same location and display it in LEDs thank you for your interest to my issue !

这里是低级实体,直接与芯片接口,抱歉重复(我试着附加一个VHDL文件)
接口协议 2.7 K 以上来自于百度翻译 以下为原文 here is, the low level entity, that interface directly with the chip sorry for the repeating ( I've tried to attach a .vhdl file ) |
