你好。我有一些CY7C64 713(100个终端)芯片,我在看CY3684USB 2开发板的原理图。但由于这个芯片不允许外部EEPROM编程,我想知道如何减少电路,使一个简单的程序员,并开始测试它。现在需要使用USB端口的电路就足够了,所以我可以用它下载代码到8051内核。谢谢你的帮助。
以上来自于百度翻译 以下为原文 Hello. I have some CY7C64713 (100 terminales) chips and I was looking at the CY3684 USB 2.0 DEVELOPMENT BOARD schematics. But as this chip does not allow external EEPROM programming I was wondering how I can reduce the circuit to make a simple programmer and start testing it. The circuitry needed to use the USB port would be enough for now, so I can use it to download the code to the 8051 core. Thank you for your help. |

我不明白你的意思是这个芯片不允许外部EEPROM编程…我的意思是,该设备允许通过芯片I2C接口编程EEPROM,所需命令可以通过USB接口发送。
以上来自于百度翻译 以下为原文 i didn't understand what you meant by this chip does not allow external eeprom programming... i mean the device does allow programming of the EEPROM through the chips i2c interface and the required commands can be sent over the u*** interface.... |

非常感谢你的回答。你是对的,我误解了“软件:8051代码运行于:外部存储设备(128引脚封装)”在其数据表中。我还有一个CYC68013芯片(100个引脚),所以我可以使用实际的CyPress工具来开发所需要的软件。我想知道如何移动数据从USB端口到程序EEPROM。为了通过USB电缆下载代码,我需要知道当我插入它时,它处理什么类型的传输(CyBoad允许我这样做吗?)当然,我需要做什么改变在我以前的职位附图制作程序员。如果有其他文件,而不是数据表和技术指南,这些芯片可能是有用的,请让我现在。来自秘鲁的问候。
以上来自于百度翻译 以下为原文 Thank you very much for you answer. You are right, I misunderstood "Software: 8051 Code Runs from: External memory device (128 pin package)" in its datasheet. I also have a CYC68013 chip (100 pins), so I could use actual Cypress tools to develop software needed. I would like to know how to move data from the USB port to programm an EEPROM. In order to download the code through the USB cable I need to know what type of transfer it handles when I plug it in (does CyConsole allows me to do that?). And of course what changes I need to do on the schematics attached on my previous post to make a programmer. In case there is other document than the datasheet and techinical guide for those chips which could be helpfull, please let me now. Greetings from Peru. |

CySalm有一个LGEPROM和SEPROM按钮,用于用EEIC文件(EEPROM图像)编程EEPROM…我相信你已经附上了开发工具包的示意图…像…一样好。我的意思是,它是这样设计的,它不限制FX2LP的基本功能…
以上来自于百度翻译 以下为原文 cyconsole has a LgEEPROM and SEEPROM button which are used to program the EEPROM with the iic file (EEPROM image)... i believe you have attached the schematic of the development kit... it is fine as is.... i mean it is designed such a way that it doesnt restrict the basic functionality of fx2lp... |
