Hi,
I would use an FPGA to controlle the display, because the VGA timing is more easily to handel. By using a microcontroller, you would have to care about how long your instructions take, etc.

Have you already tried to reinstall the drivers for your USB host controller(s)?
Maybe you should deactive and deinstall all drivers for the cable and the host controller(s) and than reinstall them once again. I had cases where this fix helped.

usb to rs232 driver not recognized
Hi,
What OS are you runnning on your machines (my crystal ball isn't working today...)? Have you tried to install the driver manually?
The converter chip used on this converter is a PL2303, as you can see in the link you have posted.

Re: what is valley current?
Hi,
In what context did the term"valley current" appear to you? Generally it used to describe the minimal value of na alternating current, for example it can be used to describe the output ripple of a switching-mode power supply.

Hi,
you may want to look at the official information and tutorials from Sun: https://java.sun.com/docs/books/tutorial/
Some further questions:
Why do you want to learn Java? What platform (CPU, operating system) are you using? What kind of applications do you want to code? Are you already...
@flanix:
Thanks for your answer, but i think you didn't really get my problem.
@FvM:
What i want to do is multiply two 32bit vectors, assign the result to a 32bit vector and than add a 32bit vector. My compiler and, as far as i know VHDL itself, longs for a 64bit vector as result of the...
Re: Help on C++
Hi uditkumar1983,
I'm both HDL designer an C++ programmer. When we talk about a C++ programm, we do not "instantiate" a code like we can instantiate an floating-point-adder-code in VHDL, for example.
What you want may be a library:
You Write one C++ file where various functions...
Hello,
I want to multiply two 32bit vectors and add a 32bit vector to it. As we know, if we multiply two 32bit vectors the result is a 64bit vector. I know that the result of the multiplication in my design will not exceed 32bit, so i wrote a code in a style like this:
signal arr1 : signed(31...

Hello,
I'm afraid it is not possible to directly access the signals of the DDR SDRAM. Usually, if we are speaking about standard x86 technology, the memory is connected to a MCU (memory management unit) that is either integrated on the CPU (AMD), or on the Nordbridge of the...
Hi,
"very high speed" in VHDL is more of a advertising term. VHDL is just the language ans has nothing to do with real timing parameters of your target. So it VHDL is not fast than Verilog, SystemC or others, if you have thought about this.
Proporgation delay is a parameter of the target (FPGa...
Hello,
That's right, you can remove your extrenal resisters if you are using the internal pullup/pulldown options in your FPGA. Also, some FPGAs allow on-chip terminating to terminate RF transmission lines. This is used for high-speed memorys like DDR SDRAM, for example.
Best regards,

Hallo AdvaRes,
you're right, "from 6200MHz" means that the VCO output frequency is 6200MHz, or to be more specfic, the carrier of the output signal is at 6200MHz.
Best regards,

Hello,
If you realy want a infite loop that actually looks like an infite loop, you can write the following code:
#define ever ; ;
for(ever) {
//your code
}
;)
