嗨朋友们,我的问题非常简单我读了所有关于ADC DAC的文章也阅读了用户指南。
。 请有人告诉我有关ADC ...我有(+ 1,-1V)AC Source我在6针接头J7上连接这个源VINA端口 我怎么能接受这个信号???? 什么是引脚位置VINA ?? SPI是什么? 当我们连接信号VINA或VINB时,有人告诉我们如何获取此信号数据... 关于ADCin UserGuide(模拟电路捕获)的知识:)) NET“SPI_MOSI”LOC =“T4” 净 净 NET“AMP_SHDN”LOC =“P7”“AMP_DOUT”LOC =“E18” 净 “AMP_CS”LOC =“N7”“SPI_SCK”LOC =“U16” VINA端口位置在哪里:)所有这些端口都有1个宽度,但是我们的信号D [14]我们必须使用哪个端口才能找到我们的信号.. 请高手解释一下如何逐步使用这个过程:(( 以上来自于谷歌翻译 以下为原文 hi friends, my question is very simple i read all paper about ADC DAC also read User Guides. . please someone tell me about ADC... i have (+1,-1V) AC Source i connect this source VINA port on 6-pin header J7 How can i take this signal???? What is pin location VINA ?? what is the SPI ?? plese someone tell us when we connect our signal VINA or VINB how can we take this signal data... there is no knowledge about ADC in User Guide (analog circuit capture) :)) NET "SPI_MOSI" LOC = "T4" NET NET NET "AMP_SHDN" LOC = "P7" "AMP_DOUT" LOC = "E18" NET "AMP_CS" LOC = "N7" "SPI_SCK" LOC = "U16" where is the VINA port location :) and all of these Port have 1 width but our signal D[14] which port we must use to get our signals.. please someone explain how to use this process step by step :(( |

嗨朋友们,我的问题非常简单我读了所有关于ADC DAC的文章也阅读了用户指南。
你有什么板? 这是Xilinx设计的开发板吗? 你的问题并不简单。 请有人告诉我有关ADC的事。 首先,您需要知道您正在使用哪个ADC。 它们并非都是一样的。 然后查找并阅读ADC的数据表。 你以前用过ADC吗? 我有(+ 1,-1V)AC Source我在6针接头J7上连接这个源VINA端口 我怎么能接受这个信号???? 语言问题 - 我不明白这个问题。 什么是引脚位置VINA ?? 你有电路板原理图吗? 什么是 SPI? 串行外设互连,一种非常常见的低引脚数数据接口。 看到这个网站。 - 鲍勃埃尔金德 签名:新手的自述文件在这里:http://forums.xilinx.com/t5/New-Users-Forum/README-first-Help-for-new-users/td-p/219369总结:1。 阅读手册或用户指南。 你读过手册了吗? 你能找到手册吗?2。 搜索论坛(并搜索网页)以寻找类似的主题。 不要在多个论坛上发布相同的问题。 不要在别人的主题上发布新主题或问题,开始新的主题!5。 学生:复制代码与学习设计不同.6“它不起作用”不是一个可以回答的问题。 提供有用的详细信息(请与网页,数据表链接).7。 您的代码中的评论不需要支付额外费用。 我没有支付论坛帖子的费用。 如果我写一篇好文章,那么我一无所获。 以上来自于谷歌翻译 以下为原文 hi friends, my question is very simple i read all paper about ADC DAC also read User Guides.What board do you have?

You connect your input signal to an ADC, and then use the FPGA to read the ADC. Read the fscking manual for your board.

谢谢你bassman59我看到没有VINA或VINB的引脚位置我必须将我的信号直接连接到VINA或VINB输入。
然后我的信号进入ADC(在FPGA上)我必须读取ADC以获取信号值...有些引脚用于ADC,据我所知。 主要问题是。 我的信号-------> ADC / DAC ----> X我怎么读X ??? 如果您知道,请解释我如何在硬件协同仿真中使用ADCblock。 谢谢 以上来自于谷歌翻译 以下为原文 thank you bassman59 i see there is no pin location for VINA or VINB i must connect my signals directly to VINA or VINB inputs. Then my signal goes to ADC (on FPGA) i have to read ADC for get the signal value... Some pins using for ADC as i understand. The main problem is that. my Signal-------> ADC/DAC----> X How can i read X ??? and if you know please explain me what should i do to use ADCblock in hardware Co-Simulation. Thank you |

如果这是Xilinx设计的开发板,如果您在使用板上安装的标准FPGA设计时遇到问题,则应将此问题发布在电路板和套件论坛中。
如果您正在尝试学习FPGA设计,这是您的第一个项目,那么您应该从一个更小的项目开始。 从一个非常小的项目(只有几个门和输入和输出引脚)开始,将使学习设计工具和设计语言变得更加容易。 - 鲍勃埃尔金德 签名:新手的自述文件在这里:http://forums.xilinx.com/t5/New-Users-Forum/README-first-Help-for-new-users/td-p/219369总结:1。 阅读手册或用户指南。 你读过手册了吗? 你能找到手册吗?2。 搜索论坛(并搜索网页)以寻找类似的主题。 不要在多个论坛上发布相同的问题。 不要在别人的主题上发布新主题或问题,开始新的主题!5。 学生:复制代码与学习设计不同.6“它不起作用”不是一个可以回答的问题。 提供有用的详细信息(请与网页,数据表链接).7。 您的代码中的评论不需要支付额外费用。 我没有支付论坛帖子的费用。 如果我写一篇好文章,那么我一无所获。 以上来自于谷歌翻译 以下为原文 If this is a Xilinx designed development board, and if you are having trouble using the standard FPGA design which comes installed on the board, you should post this question in the boards and kits forum.

我知道这篇文章真的很老了,原版海报不再需要这个答案了,但今天我遇到了同样的问题,谷歌搜索结果在这里指出了我。
所以,我会在这里回答所有其他googlers,他们的结果和我一样。 VINA不需要在UCF文件中连接。 在UCF中甚至没有提到它,因为它是一个硬连接到ADC的物理引脚。 只需将模拟信号直接连接到该引脚即可。 以上来自于谷歌翻译 以下为原文 I know this post is really old and the original poster no longer needs this answer, but I had the same problem today, and google search results pointed me here. SO, I'll answer here for all the other googlers who end up here the same way I did. VINA doesn't need to be connected in the UCF file. It's not even mentioned in the UCF because it's a physical pin that's hard-wired to the ADC. Just connect the analog signal directly to this pin. |

您好,我知道这篇文章已经过时但我仍然遇到这个问题。我正在使用Spartan e3主板。
我尝试使用Xilinx Platform Studio(EDK)添加xps_delta-sigma ADC IP,并将其连接到mp_plb总线。 我在编程时使用了以下代码但是我只得到0值,即使我将VINA拉到vcc: / * ADC PROGRAM * / #include“xparameters.h”#include“stdio.h”#include“xutil.h”#include“xdsadc.h”// ============== ======== MAIN ============================= int main(void){u16 ADC_OUT; XDsAdc ADC; if(XDsAdc_LookupConfig(XPAR_XPS_DELTASIGMA_ADC_0_DEVICE_ID)){xil_printf(“Configuration OK r n”); } if(XDsAdc_Initialize(& ADC,XPAR_XPS_DELTASIGMA_ADC_0_DEVICE_ID)== XST_SUCCESS){xil_printf(“Initialisation OK r n”); } XDsAdc_EnableConversion(& ADC); while(1){ADC_OUT = XDsAdc_ReadInput(& ADC); xil_printf(“ADC_OUT =%x r n”,ADC_OUT); } return 0;} 有人可以告诉我他们如何使用XPS(EDK)连接他们的ADC吗? 我需要更改.ucf文件吗? 我是否需要添加到IP2INTC_Irpt,AgtR,DACout,Sample的连接? 我在设计中做错了什么? 谢谢, -Omri 以上来自于谷歌翻译 以下为原文 Hello, I know this post is old but I am having this problem still. I am using the Spartan e3 board. I tried adding the xps_delta-sigma ADC IP using Xilinx Platform Studio (EDK), and connected it to the mp_plb bus. I used the following code when programing but I am getting only 0 values, even when i pull VINA to vcc: /* ADC PROGRAM */ #include "xparameters.h" #include "stdio.h" #include "xutil.h" #include "xdsadc.h" //====================== MAIN ============================= int main (void) { u16 ADC_OUT; XDsAdc ADC; if(XDsAdc_LookupConfig (XPAR_XPS_DELTASIGMA_ADC_0_DEVICE_ID)) { xil_printf("Configuration OK rn"); } if(XDsAdc_Initialize (&ADC, XPAR_XPS_DELTASIGMA_ADC_0_DEVICE_ID) == XST_SUCCESS) { xil_printf("Initialisation OK rn"); } XDsAdc_EnableConversion (&ADC); while(1) { ADC_OUT=XDsAdc_ReadInput (&ADC); xil_printf("ADC_OUT=%x rn", ADC_OUT); } return 0; } Can someone provide me with how they connected their ADC using the XPS(EDK)? Do i need to change the .ucf file? Do i need to add connections to the IP2INTC_Irpt, AgtR, DACout, Sample? What am i doing wrong in the design? Thanks, -Omri |
