    problem: sending for fpga to pc by rs232

    Have a look here: https://www.edaboard.com/threads/156656/ Download the serialinout_1379.zip file there. The SerialOut.vhd / SerialOut_Tb.vhd look like the files you will be needing.

    Spartan 3e FPGA VGA problem

    If your LED/LCD supports such a 640x480 resolution (as it should), then it will either stretch/enlarge the signal or just use a smaller portion of the screen for it. Basically, the LED/LCD will do it's own upscale/downscaling of the signal on the input. As long as you provide a supported...

    Spartan 3e FPGA VGA problem

    The LED, LCD, or CRT, monitor obviously must support the 'signals' you are generating. Basically it should not matter what kind you are using, but it might be that the 'older' electronics (the 'analog'/'non-digitzing' electronics), might be more 'forgiving' when using signals that are not 'up to...

    Spartan 3e FPGA VGA problem

    Well, let's assume above code is correct. Other than above code, you (should) have other code as well. By this I mean the code that instantiates above entity and 'connects' to the real hardware. It is this code that, could, probably be the problem. For instance, above instantiation needs a 50...

    And have YOU given it any thoughts yourself? Please share it with us. How do YOU think you should 'solve' this. Most people are willing to help, if you get into problems with your solution but are not willing to help with something that looks like some homework assignment (and the one asking has...

    [SOLVED] MicroBlaze in Altium Designer

    Well, the error 'EDK not installed' relates to using MicroBlaze. This is part of the EDK (from Xilinx) and is not free (as far as I know). So up/downgrading to another ISE version will not make any difference, if you don't have a license for the EDK of Xilinx. Using a TSKxxx processor will not...

    Constructive criticism on Power Supply for Xilinx FPGA and CPLDs (attached pic)

    I'm missing a lot of smaller cap's in your design. Note that the larger cap's are typically for buffering, and the smaller for 'filtering'. If a design shows three cap's, say 1 nF, 100 nF and 10 uF, you should place all three cap's because they are there for different purposes. Don't think that...

    [SOLVED] MicroBlaze in Altium Designer

    I omitted -some- files from the Output folder. I -completely- emptied the History folder, but this holds just old source files. I left out some (generated) binary and hex files. The reason was their size. With these, the zipped file would have been over 1MB (more than 4 times the current size)...

    [SOLVED] MicroBlaze in Altium Designer

    Well yours seems to be a Summer 09 project. I have Release 10 and I initially tried it using the Summer 09 'setting', but this failed (simply because I don't have the Summer 09 files ...) After setting it to use Release 10, there were no problems compiling the C code. Here is the output of the...

    [SOLVED] MicroBlaze in Altium Designer

    Well, I meant a --complete-- project. I don't think single piece of code this compiles without doing additional 'work' on it (creating a project; setting it up etc). You already shown the 'architecture'/'platform'/'code' as screendumps, which I assume are part of the project and are necessary...

    [SOLVED] MicroBlaze in Altium Designer

    Maybe if you post your -full- project code, someone else might try compiling it ... Assuming that code can be used directly -as is-, I myself might give it a try ...

    Just part of an update, yes (not necessarily the very latest though - my update license stopped some time ago)

    [SOLVED] MicroBlaze in Altium Designer

    There are two possible pal_init.c files One, as fa as I can see, form build 22033, and another from build 22066. The 22033 seems identical to yours (have not checked it literally). Here is the 22066: /******************************************************************************\ |* |*...
