I want to use cypress fx2  to emulate epp parallel port can any one help to develop code  for fx2 .or any application note regarding epp emulation on fx2

Hi,

I have a question When is try to build the firmwarer for FX2LP using keil uVision2.

The build result is shown attached pic.

I can’t find the exit-code =4

also, I don’t know what is means

could you give me solve or advice about this problem.

My dev system base on windows10, and I try also windows7 dev system too. But it’s result same.

Hi,

I need SPICE/ IBIS Model for FX2LP CY7C68014A.

Please let me know where will I find it..??

Thanks,

Dhara

Hello

i am new at cypress. i used avr, nxp, stm32 but i havent used cypress devices before. when i saw psoc arm and psoc creator i am amazed and i liked it.

Now i see lots of usb devices on cypress. 

i want to send data from psoc arm  to usb 2.0 / and from computer i want to send some data to psoc 5lp. there are lots of usb modules but i cant select them clearly. For example i measured adc and i want to send it to computer. but i dont want to use usb/uart converter. i need fast communication. usb2.0 12mbit/sec or 480mbit/sec.

Can you help me which one must i use?

thanks in advance

Hi!

I'm new with CYUSB and met some problems. I have made my own PCB with Altera FPGA and CY7C68013A. And I have made a mistake that I set the IFCLK pin in FPGA side as an input only pin so I have to use 68013A's internal clk.Is my understanding right that I can use it that way in synchronous slave FIFO?

I have test my code, and found when I assert SLOE and SLRD, FD[7:0] can set the first data correctly but it seems that the FIFOptr never change, data did not change and empty flag remain high.then I try it in writing, than I found the same problem ,Ican see the FPGA program function well that the FD[7:0] repeatly raising from 0 to 256, SLWR low and IFCLK in a sin curve but empty flag still low. 

I also tried Asynchronous mode and met the same problem. 

I have upload my code. It wouldn't be more thanksful from me that anyone could help me to solve that problems. 

I am in need of a a USB cable solution that would let me use an old CY3672B unit on USB.  I assume the "USB" version of the programmer just used a USB->parallel adapter cable as I see signs of FTDI FTD2XX drivers in the software.  Might there be a commonly available "USB printer" cable based on the FTDI chip that would work?

Alternately I can probably get by with an old version of the CY3672 programmer software that works with parallel ports on WinXP if I absolutely had to.

thanks,
Steve

hi.

when i copy fw project from c:\cypress\usb\target\fw\lp (all files in the folder) to an other location for example: ~my documents\keil_prg\lp and open the project with uvision3 it does not know the path for EZUSB.LIB and USBJmpTb.OBJ it looks in ~my documents\keil_prg\lib\lp for it .

also in another project when I write :

#include "fx2.h"

#include "fx2regs.h"

#include "syncdly.h"

after build this error occures : can't find file 'syncdly.h'

I checked for the file it was in the same folder as fx2.h and fx2regs.h in "c:\cypress\usb\target\Inc"

also unchecked  Project -> 'Options for Target' -> the 'A51' tab -> and uncheck 'Define 8051 SFR Names'. according to :

could you please help me?
