在外部EEPROM和另一个PIC控制器之间使用两条线路进行通信,所以我把SCL和SDA连接起来作为公共通信线路,通过控制SS引脚和外部EEPROM中的一个引脚来设置主控制器之间的通信。这是可行的还是必须改变的。
以上来自于百度翻译 以下为原文 I try to use two lines to communicate between external EEPROM and with another PIC controller.So I connected SCL and SDA as common communicate line.By controlling SS pins and A pins in external EEPROM to set communication between the main control.. Is this will work or have to change something. |

SPI通信你对此有把握吗?看着我,就像你的i2C线一样。
以上来自于百度翻译 以下为原文 SPI communication Are you sure about that? Looks to me like you're wired for I2C. |

嗨,有一些信息是强制性的给予帮助时,在这样的主题。你想用什么样的PIC设备类型?您想使用的EEPROM设备类型是什么?你想做的事情,是可能的,以前已经做过了。你必须改变一些事情。MySLeMeTest:同样,当启动一个新线程时,不要期望或假设读者通过您可能已经编写的其他线程返回排序。解释你在做什么,以及你已经做了什么把戏。迈西尔
以上来自于百度翻译 以下为原文 Hi, There are some information that are mandatory to give when asking for help in subjects like this. What PIC device type are you trying to use? What EEPROM device type are you trying to use? What you are trying to do, is possible, it have been done before. You have to change something. Mysil Edit: Also, when starting a new thread, do not expect or assume that readers go back sorting thru other threads you may have written. Explain what you are up to, and what trickery you have already done. Mysil |

如果你使用24LC512,你将不得不使用I2C。但是你似乎不知道I2C和SPI之间的区别。为什么你提到一个“SS PIN”,什么是“PIN”?你是否意识到你在1中发布的图式只是一个微小的缩略图,它是不可读的?你是否意识到你完全从你的1中移除了图像?我的印象是你真的不知道你想做什么。在问威廉希尔官方网站
“细节”之前,你应该解释全局图片,什么是你真正的问题(项目或任务)。为什么你不跟上你以前的PothTutp://www. McCHIPC.COM/FUMMS/M10957.6ASPX?
以上来自于百度翻译 以下为原文 If you are using the 24LC512 you will have to use i2c. But you seem not to know the difference between i2c and SPI. Why do you mention an "SS pin" and what is "A pins" ? Are you aware that your posted schemetic in #1 only was a tiny thumbnail image, which was unreadable ? And are you aware that you just removed the image completely from your #1 ? My impression is that you do not really know what you want to do. Before asking technical "details" you should explain the global picture,- what is your real problem (project or task). Why didn't you just follow up your previous post http://www.microchip.com/forums/m1039576.aspx ? |
