Hello all, I have to connect fpga(spartan3) with C51 (5V), the spartan3 IC only support up to LVCMOS 3.3V, and I do not want to isolate them with a CPLD, what shall I do? Regards, Davy Zhu
I am working on an fpga based DSO project. I would like some input on the fpga/adc clock. The project utilizes 2 adcs capable of up to 250MSPS (Maxim 1121s) and I plan on using a Xilinx Spartan fpga. For acquisition there needs to be several timebases. These include: 10Mhz, 25Mhz, 50Mhz, 100Mhz, 125Mhz, (...)
Hello to everyone, I am very new to the world of fpga boards, and digital data converters, and that I deal with signal processing hardware. I am going to work with a TR4 development board produced by Terasic, such a board is mounting a Stratix IV fpga which is meeting my performance requests. Now the point is that I would like to (...)
Hi Vacuum, (hehe that's funny) The Xilinx Virtex-4 and Virtex-5 can input 1 gigabit/sec per differential input, so you may be able to connect your adc directly to the fpga. Inside the fpga, you could split the data into several parallel paths, and process them at a comfortable clock rate. Why would you want to use (...)
It's advised to connect an adc's both AGnd and Dgnd pins to analog ground plane. What i wonder is is this also apply to reference inputs? I have system that has a single 24V input and several outputs as shown in figure. But I'm confused how to connect the grounds. I decoupled all outputs, they are connected at a point (...)
Hello; I want to use the adc on spartan 3e kit. I think I need to use SPI interface to connect the adc to the fpga. I wonder if I can find a VHDL source code for using adc with SPI interface. Please help me... Thanks...
Friends, My doubt is that whether we need to do something special to connect fpga IOs to adc output (something in programming) or its simple. I connected AD9224 40 MHZ adc to SPartan 3 fpga. As long as I give only clock signal to adc from fpga data (...)
how i connect sparten 3E xc3s500e board to my pc .. my project is fpga implementation of uart design . i completed my synthesis using ise design suite..and generated the programming file .what should be my next step..
Hello, I am starting to research the market to buy a signal processing board for communications signals, including at least 1 adc (150Msps, 14bit), 1 DAC (200Msps, 14bit) and of course an fpga. My purpose is to perform signal processing to signals with bandwidths of 40MHz maximum, and I am having a lot of trouble while choosing an fpga (...)
hello u can use c8051f005 which have built in adc u can have the interface on 8051 tutorial sites if u want to connect the adc chip then 0808 is good for it keep on doing it best of luck bye PD
When you interface adc with MCU the following connection should be made 1. Data Line (you can connect to port pins of 8051) 2. Chip Select, (You can make GND for always enable of the PIN) 3. SOC,EOC ( EOC can be given to external interrupts to avoid polling); SOC( start of converstion should be given from microcontrooler to (...)
You have the tx part ( infrared) and the receiver part (infrared receiver) you have to give a signal to the infrared tx. if the turning on of the tx you want it to be controlled by the pic then, it has to be connected to the pic as output. if not ( make always on) no need to connect it to the pic. As for the receiver it has to be an input to the
NOt sure why do you need multi fpga design details, basically two problems running out of pins, and running out resources. in both cases it is interface between devices, and protocol is challenge. Fro configuration stand point of view I am always using small external MCU and external flash, never connect fpga in chain, in case during debug (...)
Hi, You can use a current transformer to sense the current, get the RMS value of the current using an RMS computing IC and scale it and connect to adc. Regards, Laktronics
LOL! are the DSP board and fpga board separate boards? Why you want to connect them with ethernet ? it is funny. you can use DSP's McBSP as you know and develop the suitable module on fpga side you can use Host Port Interface also there are other means like I2C ( don't knoe if the DSP has I2C port ) and even the (...)
hi all, I would like to design a new card with Timing Filter Amplier,Constant Fraction. Discriminator fpga, adc 100Mhz or more if somebody has an idea... Thank's in advance best regards

If you are using microcontroller then you can probably connect your adc/DAC to the SPI interface of MCU if your adc/DAC can support SPI interface. Alternatively, you can also use polling method with the normal I/Os to generate clock.
Just connect the adc input to VCC using a large resistor (large enough to not load your analog circuit). With no input signal from your curcuitry the adc will read full scale and you´ll know it is disconnected.
thank you for u r reply i will try u r suggestion. by the way , in how many ways we can connect fpga to computer i know one method---using RS232 port are there any other methods i am using cyclone kits
I've been scouring the web looking at different homebrew oscilloscope solutions and have found ALL of the projects that are capable of greater than a few hundred kHz are using an fpga or CPLD. Why is that? What would a uC need to offer in order to fill this block of the designs? Thanks, -Rocko
i've got idea , like we'll connect fpga on one side and LDI on the other side. fpga will fetch the data (MSUs) from E1 transceiver by issuing an address of the register where the MSU is stored. i'm looking into it in detail...lets c..
Your problem may be caused by several factors: 1) Your supply is not 5V, 2) Your supply is incorrectly connected to the IC, 3) Your ICs are DOA, 4) Your PCB has routing problems. Check all, assume nothing.
hai im confuse , by reading datasheet of ICL7107CPL (adc) , its appear that the adc doesnt need any 7 segment LED display DRIVER before connect to 4 digit 7 Segment LED display, actually, do i still need to use driver before i connect that adc to the 4 digit 7 segment LED display? futhermore, what (...)
Can i use McBSP for interfacing of stereo signal (left and right channels) i.e. I2S. if yes, then how? I want to connect to adc with McBSP. how can i pick up signal from two McBSP. As clock to both adc is same. I want to get signal from both adcs with different input signals. How can i get data from two McBSP without (...)
You can connect the fpga to any BUS without the need to a buffer. It simplifies the design and make it easier to make changes in the future. Long time ago, we had a board with 2 TI DSPs, and 2 Motorola Power PC processors together with 2 memory blocks , we used a large fpga to connect them together and act like a common (...)
hey guys i'm using PIC 16F877A with 10bit adc + i'm using highly stable Power supply along with capacitors + i'm using a 47uf capacitor on adc channel & the Digital volt meter is reading a stable value, but i'm not able to get a stable adc value why? what should i do now? i am also doing Average of adc value & the (...)
I am trying to use the USB port in my ml501 (vertex 5). I know how to send data through USB port, but I am not sure how to receive it. How can I identify USB ports in the USB drive on the board to connect fpga to them.
I'm a bit confused, you say that you have a dual channel adc with 10bit parallel outputs, why do you want to isolate that from the fpga using optocouplers, usually the voltage of the adc can be connected directly because they can work with 3v3. If you want the isolation for level translation then you can simply use (...)
I saw one used once up to 3 ghz, and it worked suprisingly well. It had a pin with the signal, and 8 pins around it, in a square, connecting the two board grounds together.
I am using a LDR to sense light. i have attach a picture how i connect it up to the adc. The problem is when i connect it up to MCT the mct analog input is 0V, it just cannot sense any voltage. But when i connect the adc up to a voltage source it work perfectly normal. The resistance of the LDR is huge (...)
Hi.. This is what I have this far, I want to connect fpga Spartan 3E and MQ-7 CO gas sensor. Firstly, I know that this sensor is analog device. So that I have to convert the signal. I'm intend to use Analog Capture Circuit from Spartan 3E board. MQ-7 need 2 kind of voltage: 5V and 1.4V. From the Spartan 3E datasheet, I know that I have to look fo
So...this file stores information about how to connect fpga resources. Is there another file that notes the exact resources to use ?
I'm working on a project where i'm need to display the data through USB to Matlab. For example, to use an oscilloscope. Or data acquisition toolbox. For example, to connect the adc data received and transmitted via USB as an analog channel in simulink I read the documentation, but did not understand whether there is any documentation for driver d
I have a fuel sensor in the bus which gives me 0-200 ohms. The fuel gauge is connected to it and it works on 24V. so the problem is i need an adc to be connected to it. IF i connect the adc device 0-5V (no idea on what is the potential divider in it)alone it works or gauge alone it works. I want the (...)
MCU as STM32F303 allows you to connect two adc in dual mode. Two 12bit 5MSMPS work as a ONE 10Msps Unfortunately, no one does, how to solve Front-End Amplifier for adc in dula mode. Use one amp for both adc or two for each adc own amplifier?
hi all, I want to connect micro2440 adc pin to external voltage(0v to 5v) and use 10-digit digital output. Can anyone help me with a sample code? I use linux qtopia and compile source code in ubuntu 12.04, with arm-linux-gcc. Finally, I want to send this 10-digit output(previous paragraph) to PC via rs232 protocol.I need another sample code
Hello guys, I have a question. I use Hyperterminal software to send a file to fpga. I implement a UART Rx in fpga and loopback it to UART Tx and again I want to return back same character that I send to fpga in Hyperterminal. but I have some problems. It's work for about 8000 character for 4800 bps baud rate and next it has about 20-50 (...)
Hi,all I used AD9702 from AD to translate the digital singal to differential ouput and a RF transformer to translate the differential ouput to a single output. if i do not connect the transformer, the differentail analog ouput is linear with the digital input, but if i connect the transformer, the single ouput is nonlinear with the digital
I Think this is really necessary for you to study a complete datasheet of one adc, so that you can get familiar with different important parameters of an adc. Then the really important point, is to what device you want to connect this adc ( as Fox says ) for example, suppose that you want to connect this (...)
Web cam are low resolution 320x256 pixels, and no more than 10 images per second and they get digital signals directly, so speed to get it is not big. Video signals are PAL or NTSC signals, they are analog signals with a carrier of 3.58 Mhz, so if you want to connect a parallel port to a video signal, you must connect an adc and have (...)
how have you connect the fpga with your SDRAM? Have you select the right driver standard?
Hi teachers out there! I am new in Analog Mixed Signal Design. From what I know, to simulation for INL/DNL, we input a ramp voltage and connect output adc to IDEAL DAC. So we compare with IDEAL adc output and measure INL/DNL. However we need to measure each step to get INLmax and DNLmax. If we have 8-bit = 256 steps. Am I correct? The (...)
No way. connect it with any port and it will work. Only consideration is to keep an eye on the half voltage given to the adc. regards
use the Ultrasonic TX and RX the output of the RX is connect with adc then u can easily test the levels of the water
this DAC is current-steering, in test, the SNR of DAC in one aspect (sample and signal frequency is changed) exceed 50dB, but the SNR of ideal 8bit DAC is 50. is it normal? or the test is wrong?
Hi my friends I have designed a hardwrae based on Spartan-3A generation, and i use VHDL to programming. Please tell me how i can realize that the fpga's configuration is completed an the fpga is ready to use. i want to use this feature to initialize my internal register by desired values. Are there any solutions to detect it by hardware or s
you could also use the adc port connect the adc port to a potentiometer, (center to adc port, max end to +5V and min end to GND) Since you need 12 positions, each position change occur at intervals of 30 degrees. or 1023/12= 85 bits (approx) To get the position number, divide the adc (...)
I have the low frequency design in VHDL already, I am using my Spartan 3e board with a 60MSPS adc and some analog parts to use as a low level oscilloscope, what I don't have is any kind of SW to connect it to the PC and control it, right now, it is all controlled via UART. If you want we can work together on this.
