Please help me regarding the problem i am facing..... Thank you in advance for your time and effort....
-> I have a EVALC board and a AD6657EBZ baord. Both are connected, powered from respective power adapter, and connected to my PC using USB cable.
->I have P501 connected/shorted, so that I can use Channel A.
->My question is , should I apply clock (Sine wave or Square wave), [I presume Sine Wave,Am I correct?] and the amplitude of clock signal? NOTE:I have a function generator Matravi FG-3000,which Iwant to use as a clock source.
->Second question is -With P501 jumper shorted, is ChannelA enabled? Do I need any further jumper connections?
-> Third question is, what should I do next to capture data. Ihave read the guide, but till now Iam not successful to get data.
->Ihave used VisualAnalog, but still failed.
-> Ihave a custom C# application made to capture data, but it returns 0 data.
-> The important partof code code are:
public string FPGA
{
set
{
SelectDevice();
int err = ADIFIFO.FPGAConfigure(value);
if (err != ADIFIFO.ERR_SUCCESS)
{
StringBuilder sb = new StringBuilder(512);
sb.Clear();
ADIFIFO.GetErrorMessage(err, sb);
throw new IOException(string.Format("Error burning FPGA file {0} [Error Code:#{1} :{2}]", value, err, ADIFIFO.GetErrorMessage(err)));
}
}
}
public bool Capture(int delay_ms)
{
SelectDevice();
int err = ADIFIFO.FillFIFOs(delay_ms);
return err == ADIFIFO.ERR_SUCCESS ? true : false;
}
public bool ReadSamples(int channels, byte[] buffer, int offset, int length)
{
GCHandle hbuffer = GCHandle.Alloc(buffer, GCHandleType.Pinned);
SelectDevice();
int err = ADIFIFO.CaptureFIFO_Bytes(hbuffer.AddrOfPinnedObject() + offset, length, (short)channels);
hbuffer.Free();
return err == ADIFIFO.ERR_SUCCESS ? true : false;
}
->
The client program is:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Arnav.Quartz.Devices.AnalogDevices.EvalBoard;
namespace EVALC.Demo1
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("API# {0}", EvalBoard.APIVersion);
Console.WriteLine("Board Count = {0}", EvalBoard.BoardCount);
for (int i = 0; i < EvalBoard.BoardCount; i++)
{
Console.WriteLine("Device #{0} : {1} [{2}]", EvalBoard.BoardInfo[i].ID, EvalBoard.BoardInfo[i].Name,EvalBoard.BoardInfo[i].Firmware);
}
Console.WriteLine();
try
{
EvalBoard b = new EvalBoard(0);
Console.WriteLine("{0} : {1} [{2}]", b.Info.ID, b.Info.Name, b.Info.Firmware);
b.FPGA = "AD6657_64k.bin";
Console.WriteLine("FPGA copied successfully");
while (!Console.KeyAvailable)
{
Console.WriteLine("Capture = {0}", b.Capture(1000));
byte[] buffer = new byte[16 * 1024];
Console.WriteLine("Read data={0}", b.ReadSamples(1, buffer, 0, buffer.Length));
for (int i = 0; i < buffer.Length; i++)
{
Console.Write("{0}\t", buffer[i]);
}
}
Console.ReadKey();
}
catch(Exception ex)
{
Console.WriteLine("{0}", ex.Message);
}
Console.ReadKey();
}
}
}
-> The code above shows my board information, but captured data printed on screen are all 0. No noise or anything.
->Please guide me through the board setup, so that Ican work atleast with Visual Analog or FIFOInterface.h api.
Thank you all again.
