USB Device Controller ISP1362

Hello friends,

I am currently using DE2 70 board. I was trying to use the DE2 board's device property( DE2 boarda as a USB device). I started with the DE2_LED demonstration.unfortunately I am not able to install the USB driver for ISP1362 USB controller driver. I am using Win Xp Operating Sytem. It does not detect my De2 Board and it never ask for the driver as said in the READ me text in the DE2_LED demonstration.

I also facing another interesting situation. Now I am not able to down load any .sof files to my DE2 70 board. It shows an error, JTAG server cant find the device.

Can any one help me in this reagrd???Thanking you in advance..

Dear Farhat,

I also had a similar experience.I could not install the ISP1362 river for one month. I solved the problem recently. You try connecting both USB cables( Blaster and Device ) from the begining. Also do this while building the project.after build is complete rmove the USB cable from Device port aand run the C program, once u get a message chip ID XXX, u connect back the Device USB, your DE2 board will be detected by the OS as a new device and it will prompt you to install the driver.

I hope this will help you...

Regars,

Mahesh

Yes, I also want to have some guides to work with the ISP1362...

Now I can read from the ISP1362 the packet from the host PC

but I cannot send anything to the host PC (PC side receive no packet)

People there,

Since I have the similar goal (to use DE2 board as a USB device) I would really like some guidelines for ISP1362 controller. How to use it, how to program it...

Please share with me any ideas...

Hello,

I'm using the wsiausb of Tonyslagle. You search wisiausb.zip in the web and use the code in your DE2 o DE2-70 board.

I am now working in a project which needs to make the DE2-70 board as a USB device and the host is the PC.

When I try to probe the system, I found these problems:

1) If I connect both the blaster cable and the device cable to the pc or only the blaster, the host

shows initially the blaster, then I download the firmware to the FPGA and the system do the Enumeration and initialization

process and the ISP1362 is recognize by the host PC. But, if I disconnect the blaster cable, the system

is not respond, then I reset the driver by the firmware and the device is doesn't show by the host.

I am using the VISA USB Raw of National Instrument and its driver in the host.

2) If I work with both the blaster cable and the device cable connected, the system can transmit data

from PC to device successful, but when I try to send data from device to host PC, it show me a timeout error.

I check the firmware step by step and it apparently work correctly.

Please, if you can probe and solve these problem, you say me..

Thanks...

Mr, I really can not find Tonyslagle wisiausb.zip drivers on the Internet !

Can you, please send it to me or tell me where to find them ?

Thank you very much!

Hi! you can search in google or in www.sourceforge.net/projects/wsiausb/

That's a version 0.1. You should review, and debugg it. I'm working with that too.

Hi everyone,

i notice some of U had using the code from DE2_NIOS_DEVICE_LED demonstration(DE2 board CD) and modify it to send 64 bytes data .

Can i know how you modify the coding?

I'm using DE2 board, and i had modify the coding from

ISR.c (void Isr_Ep01Done(void) ;void Isr_Ep02Done(void))

and

mainloop.c (void config_endpoint(void))

but i still can't make it send 16 bytes data block.

Please give me some suggestion......

thanks.....

hi,

I'm modifying the coding from DE2 board CD -> DE2_demonstrations -> DE2_NIOS_DEVICE_LED.

For the firmware of device controller for ISP1362 chip, there got six related coding: MAINLOOP.C, CHAP_9.C, D13BUS.C, HAL4SYS.C, HAL4D13.C AND ISR.C.

Where HAL4SYS.C and HAL4D13.C is hardware abstraction layer;

ISR.C is interrupt service routine;

CHAP_9.C and D13BUS.C is protocol layer;

MAINLOOP.C is mainloop.

Does anyone knows which firmware coding need to be modify and which one remains if I want to change the USB data block transfer to 16 bytes data block?

Thanks and regards,

Summer

Hi summer,

I'm doing exactly what you did 2 years ago. " I'm modifying the coding from DE2 board CD -> DE2_demonstrations -> DE2_NIOS_DEVICE_LED."

Instead, Im using DE2-70, but Im having trouble with compiling the project in NIOS II IDE 9.1. Did you have any issues with that? Is there any useful information about modifying the code that you could tell me ?

Thanks

hello all,

I have DE2-70 board and I need to work with USB device.I am now working with a domo

project "E2_70_NIOS_DEVICE_LED"on DE2-70 board.I download *.sof file and then in

NIOS II IDE I build and run it.I think it should ask for driver for ISP1362 but it donot.

I think my system should recognize USB-device as it recognize USB-Blaster.but it is not.

I am lost and desperate.I have put my one week on it and no results.

Pleaes guide me how you people working with it.

give me simple tips and ideas initially to start working with ISP1362.I am not expert in c but I have much work with VHDL and FPGAs.

Hi Farhat,

Im currently experiencing the same problem like you, Did you solve that?

Thanks,
