Do you have actual USB Analyser hardware? If yes can you check if the device is NACKing for the IN tokens?
Did you check the C# application in different version of Windows? Are you facing same issue?
Thank you for your advise.
Unfortunately, I do not have actual USB Analyzer hardware.
but I can try with different version of Windows.
I think "Windows 7" or "Windows Vista" is the different version of Windows, you mentioned.
am I right?
I tested the USB HID test with "Windows 7 Ultimate".
but I got the same result.
maybe Windows version is not the reason of the problem.
If you have any idea, please let me know.
Thank you again
I trying to make the environment as AN82072.
I am analysis the sample project that uploaded by Cypress for AN82072.
the sample project seems to be written by PSoC Creator 3.3 SP2.
so, I did compile and upload the firmware using PSoC Creator 3.3 SP2.
but Sample system is not working well.
In this time I am using CY8CKIT-050 to avoid change some code.
but To change PWM Duty Cycle, I have to push the "Update" button several times.
If you have any experience with this problem, Please let me know.
I am not experiencing any issue like I have to press "Update" button several times as mentioned with AN82072 on Windows7 with CY8CKIT-050 on PSoC Creator3.3 SP2
Thank you for your reply.
Currently, My Test environment is as below
- Windows 10, PSoC Creator3.3 SP2, Visual Studio 2017 community, CY8CKIT-050
so, Will try with Windows 7 in soon.
and I have a question for you.
Today, I tested the USB protocol with hardware Analyzer.
There are a lot of NAK for IN token.
How Can I debug for the NAK in PSoC Creator?
If you have any advice, please let me know.
Today, I have an analysis USB packet with hardware analyzer.
before you mentioned NACKing for IN token, and I checked just now.
So, If you have any advice to solve this problem, Please let me know.
Can you add the following code snippet to the main loop and try again.
/* Place your application code here. */
if(USBFS_IsConfigurationChanged() != 0)
if(USBFS_GetConfiguration() != 0)
for more details on why this is required.
Thank you for your help.
but The Problem still exists even I added the cord.
And I found that the problem related with Windows version.
I am sorry about this situation before the experiment was wrong.
I prepared clean Windows 7(64bit) and Windows 10(64bit).
And I downloaded PSoC firmware with "AN82072" that Cypress supported.
I used C# application that contained in "AN82072" for my Test.
when I test with Windows 7, it is work perfectly.
but when I test with Windows 10, it is not working perfectly, To send the data to PSoC, I should click the button several times.
If you have any opinion to solve the problem, Please let me know.
Thank you again about your help.
