I have to perform a project with spartan-3 fpga . i have xc3s400 and xc18v04 as FPGA and PROM. for performing the project i made a pcb based on the circuit from xilinx application note xapp453 "The 3.3v configuration of spartan-3 FPGAs" as below:
when i set the mode pins to master serial like...
spartan 3 parallel cable iii
as you know Xilinx download cable III circuit works with 5v and spartan-3 is 3.3v tolerant. I have a question which may seems funny.
is it possible to connect download cable III(which works with 5v) directly to program spartan-3 or should use a 3.3v kind of download...

I'm trying to make a development board for xc3s400 like XILINX SPARTAN-3 starter kit but it has not LCD interface so i decided to add this feature.
in elektor magazine there was a project about making a development board for altera fpja which used the following circuit for LCD...
I have started to make a development board like SPATAN-3 Starter kit of XILINX. I have to do this , there is no other choice for me please don't tell me you can buy it or something like this .
my reference is xilinix document ug130 which contains schematics of the board but there are some...
Re: My ICD2
Nice pack for ICD2 . there are many topics and posts about iCD2 in this forum but when a newbie want to make a ICD2 being confused.please post your complete design for icd2( schematic, pcb ,firmware , and your nice notes).your post could be a good reference for all who want to make...
you can use lm336. lm336 is a 3 pin device that works exactly like a zener diode with various brake voltages .in example there is lm336 Z2.5 & Z5,…. if you use a lm336 Z2.5 with a potentiometer like sample circuits in it’s data sheet from national semiconductor you will get a nice , low noisy...
hi checkmate thank u very much for your help.
is it possible for you to upload the ccs firmware and also i want to know if you have built your own icd from that site i used for building icd or no?
if your reference is different please tell me
thanks
hi all
for my final project i had selected icd 2 project but some needed parts didn't find in my country so i decided to make icd 1 from this site:
**broken link removed**
i have made this project but when i want to program the target, clear memory is failed and the led is blinking.
IS THERE...
microchip icd1
hi crazyduck there is no firmware in this link:
www.microchip.com/1010/pline/tools/picmicro/icds/mplabicd/index.htm
please upload this firmware or send that firmware to my email:
masoud_n_rad77@yahoo.com
i really need that firmware please send to me
thank u very much
Re: dsPIC - Microchip
hi
this question is just that i have asked frequently in this forum and i didn't give any good answer. it seems that no one has worked with this controllers.
but if anyone has worked with dsPICs please tell us about it's characteristics and please answer to this important...
