Hi,
Few days ago I have bought dozen "oldtimers". I only have one question, how to include in ISE a definitions for xc5202 series??
Or, maby to find some old development tool?
'Thank You,

Hi,
I sugest You to look at the reccomendations of the manufacturers, the first question is what is Your target application of the protoboard (general, DSP, Ethernet, PCI, PCI-E,...) and to study the literature of the manufacturer. Also, the main question is target production price. I will...
Hi,
I am planning to purchase a DLP FPGA protoboard (xc3s250e tq144 + ft2232 + sram). I would like to have some opinion about it from people that have been using this protoboard. Simple speaking, the news releases are very positive about it, and I would like to hear som "first hand" experience...
Re: newtons law
Newton is famosu for three laws of motion:
I. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.
II. The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma...
Re: INFINITY
Here I am again....
Infinity and zero are numbers, but they are very special!
1 + infinity = infinity
n + infinity = infinity
a * infinity = infinity

ide interface verilog
Hi,
It all stated a week ago, I came to an tremendous idea. Since I started a simple project in CPLD at first I wanted to interface it with uC + FT232 combination. Then I realized that for a price a leatle bit less than 10 EUR i have a USB-IDE interface and quite a nice...
It is simple,
The measurement are sensitive on frequency and it tooks quite expensive equipement (and it has to be regukarely calibrated) to make an acurate measurement.
Now a leatle bit of physics...
Look at the speaker an the microphone itself. If You neglect the electrical calculations at...
Re: INFINITY
There are two special number that are not numbers as we know, the infinity and the zero. Both of them are the universe fro their own.
If You have studied a course of mathematics on university, You coud remeber about the questions like wkat is $0/0$ and $\inf / \inf$/. Both...
xilinx parallel cable iii pinout
Hi,
I had a similar problem with the parallel cable. The solution was so simple that I was amazed: I just shortened the length of the cables from board with the tri-state drivers (74HC125) to something like 10-15 cm. After that all was working well. The length...
ftdi lpt
The FTDI produces several IC's. FT2232 is dual RS232 port with direct IO lines capability. With this IC is possible to make few things, among other JTAG or SPI driver (for a nice JTAG + Rs232 see http://www.ethernut.de/en/hardware/turtelizer/index.html ).
On the other hand if You...

I have started to develop interface, but it is a leatle bit slow process since I am working on my PhD. But if You would like we might be at contact.
My idea is this: Clock is generated from CPLD, be careful about the clock conditions. There is a good explaination about the timing on...
avr ds18b20
There is a code for avrgcc (winavr). Please, go to www.avrfreaks.net the registration is free, there You could find a lot of projects and discussions concerning AVR. A search for ds18b20 returned several projects. I personaly had a problem with DS18B20 protocol, I believe that when...
I use AVR and I am intending to start with ARM (I have purchased few ARM7 uC's, and they are waiting for my free time)
I hav quite nice expirience with AVR, comparing to PIC I could say that they are more reliable. Maybe that a friend of mine had a bad experience with a PIC (16f84 as I...
attiny2313 fuse bits
I also had some trouble with my first attempt for avr910 ISP. But after that I started to use the parallel port programmer. Also good and a quite simple programmer is ponyprog / siprog combination, siprog has a simple contruction on RS232, and You could power the attiny...
Have You considered an SP6644 from sipex, it is capable of producing from 2.2V up to 5.5V and as I remeber corectly it is capable of doing it even from 0.88V batery. it has several uA $10^{-6} A$ and I think that exixst in Farnell catalogue. I think that it neades something like one coil, five...
