    Microblaze Stack and Heap address.

    Hello all, I am using a spartan 3A starter kit.I am trying to implement a simple DDR2 memory test system. In my linker script i have configured the Code and Data memory,stack and heap to be located on the LMB or blockram.The size of blockram is 8k,which,by my understanding is the maximum i...

    Water leakage detection : time crunch

    Thankyou for the reply.. I will drop the idea of CTMU. But there is a requirement update... This circuit is to be for detecting different fluids with different resistance levels. So I will have to use an analog input signal with varying levels for different fluids.. Now I am a little bit...

    Water leakage detection : time crunch

    Well here is the idea which I have in mind.. Two probes placed side by side with a known high resistance between them. Supply a pulsed voltage to one of the probes and Monitor the current through the circuit through an analog input. When water floods in to the middle of the 2 probes the...

    Water leakage detection : time crunch

    Hello all, I am not sure if this should be posted here,but..here goes. I am trying to implement a water leakage sensor with the help of a microcontroller. How can this be done? My idea was to measure the resistace change in the conducting path when there is a water leakage. In this case can...

    [SOLVED] SPARTAN 3A Starter Kit connection to laptop

    Hello all, I have a Spartan 3A starter board. I would like to know which one of the below 2 ethods will be a better way to interface it to my laptop (No RS-232) fro debugging. 1.Use an RS-232 to to USB covertor and connect to laptop. I hope that the convertor will have a Virtual com port...

    Multiple DDR interfaces

    :-) .. I had 12 layers in mind... dont ask me y.. ---------- Post added at 17:20 ---------- Previous post was at 17:17 ---------- As of now I a planning to have just DDR interfaces on the board...As many as possible.. I guess 4 will be a reasonable number... Well the idea is still kind of...

    Multiple DDR interfaces

    Thank you TrickyDicky... in the hardware Point of view is this feasible? On How many layers of PCB can this be acheived?

    Multiple DDR interfaces

    Hello all, I am a beginner in FPGA design. I have come across some Xilinx FPGAs which are capable of supporting multiple Memory control Blocks (MCB). Does it mean that I can build a system with Multiple DDR interfaces on the same FPGA for eg: A DDR,DDR2 and DDR3 on 3 different MCBs (Provided i...

    [SOLVED] Direction of Motor Rotation from 3 Hall outputs.

    Well,i guess i will have to go with the Microcontoller option. Will be using the CCP modules on PIC MCUs for speed measurement. Havent decided how to implement the direction part yet.

    Xilinx Evalboard choice

    Hi, Probably u can try a silica Spartan LX9 Microboard with A/D and D/A convertor pMODs from Digilent. just a suggestion if ur looking for low cost solution. May be people can give a better insight if you explain your requirement a little bit.

    [SOLVED] Direction of Motor Rotation from 3 Hall outputs.

    Hello All, I have a problem.I need to find the direction of rotation of 5 motors from their Hall sensor outputs (3 outputs each). I understand that Comparing the pattern on the sensor outputs will give its direction,ie each direction will give a repeatable sequence. I think this can be done...
