Issue regarding - Experimental replication

[shuvra1]

Enclosing all relevant docs. Sort it out. @Sahil_K

Hello Shuvra1,

Let me give you some advise because I see your forum-questions daily coming by, without much response. I think you might get more response when you stick to some basic rules such as :

- Dont just place your code without a clear description on what you cant achieve.

- Dont start a new forum-topic daily (or even more than one daily). Stick to ONE forum-topic because than someone who reads it can see what you allready tried

- Make a clear difference in parts of your project that might be solveable by PSOC5 specialists and parts that have nothing to do with PSOC5.

- Be very clear on which hardware you use, what you allready tried and what you cant get working

- Try to get in touch in a polite way with the original writers of the project you're trying to replicate. 

Please treat this answer as positive feedback, and as a way to get more help. Sorry to say so but placing a new topic of a problem daily (or multiple times a day) will not be inviting for other people to help you. Also accept that some of your technical problems probably have nothing to do wiht PSOC hardware, software or tools.

[Len_CONSULTRON]

shuvra1,

I can appreciate that your attempt to get a Potentiostat project for the PsoC5LP to work might be frustrating.

As Patrick indicated your forum "screaming" is not working to your advantage.  There many more expert forum users that would like to help where they can.  Many of these users, like myself, are generally familiar with parts of the PSoC5 resources and some external circuit and SW principles.

As for myself, I am not familiar with the Potentiostat circuit general operating principles as well as Python scripts.  Therefore in these matters, I have little to no experience.

We have an expression we commonly use at work:  "How do you eat an Elephant?  One piece at a time."

The Potentiostat project is the 'elephant'.  We as forum users may be able to help with bits and pieces of the project.

I'm assuming that you found the Potentiostat project from somewhere that the Author Olav Bjerke created.  This person has full knowledge of the entire project SW and HW.

Have you tried to contact Olav Bjerke directly?

When you do, the first thing he will probably ask is did you recreate the external circuits and wiring that matches the project requirements.

In general, if I were starting a project from scratch, I would determine the internal and external circuits needed for each section and get them working separately.  This is basically like crawling before trying to walk.  Once I made sure each functional section is working to the needed specifications, I then try to code all the sections to operate as a functional system.

This method is the equivalent to "Eating the elephant one piece at a time."

It sounds like you have jumped into someone's project and expected it to work.  If all the external circuits are not attached properly, this is almost guaranteed not to work.

You need to understand Olav's project and its' pieces.   Therefore you can present issues to the forum for each piece.

For example:  The USBFS component in TopDesign appears to be configured as a UART style interface.   Have you tried to communicate to it using a PC terminal program?

[Len_CONSULTRON]

shuvra1,

I have done a quick check of the Potentiostat.zip you've provided.

There are a few issues with the code you provided.  Some of these issues MIGHT BE contributing to issues you are seeing.

I noticed that the Olav Bjerke  project uses the CY8CKIT-050 evaluation board.  However it appears you have changed the target device to that which is used on the CY8CKIT-059.

What other changes have you made to the original Bjerke project?

Do you have the original Bjerke project?

I can see based on Bjerke's code that until the PSoC establishes a 'correct' communication with the USB port on the PC, it doesn't proceed.  This might be the first issue that needs to be corrected.

I also noticed that the USBFS configuration VID and PID are 04B4 and F232 which is the same as that of the USB_UART.  Also the "Device Class:" is listed as FF (Vendor-Specific) which is different than the USB_UART.  This might be a problem.   

Were these parameters changed from the original Bjerke project?

[shuvra1]

Yes It's an original olav bjreke project . That parameter has been changed when it was not working (Original USBFS -Attached below) .Please guide me further on this. Thesis enclosed.Please guide me & revert me back. What ever necessary changes you might required & provide those files me back after major changes done by you. It's a humble request to you.  HEX & GUI (EXE).

[Len_CONSULTRON · Accepted solution]

shuvra1,

The files you provided in the previous post is EXACTLY the same as the ones you provided in the first post of this thread.

The Potentiostat.zip is NOT the original Olav Bjerke project.  It has been altered.

If I can obtain the original  project, I might be able to glean new information that might help you.

The main issue starts with the fact that you changed the VID and PID from the original settings to the settings used for the USB UART.

Based on this pic:

you are stating the original VID and PID are 0x04B5 and 0x0081 respectively.

All the parameters listed in the "Device Descriptors" are important to the USB communications used by the Python scripts.

I must note that I have limited experience in USB configuration.  It would be best for someone else with more experience to weigh in on this issue.

Once a USB slave device is powered up on the USB bus, the PC looks for a '.inf' file where the VID and PID match.  In this case, I changed the VID to 0x4B5 and the PID to 0x0081.

You will notice in a Device Manager snip, that the device "Potentiostat" shows up but the icon symbol on top of it () indicates it is not operational.

Reading the event for this device it indicates the read VID and PID but the Driver Name: equals null.  (It could not identify the driver to use.)

Since it couldn't find the .inf file that matches the VID and PID, it couldn't determine which .sys driver file to load.  (Sometimes a special .dll file is also used.)

This is why the original  Olav Bjerke project files may be necessary.  Beside setting the proper USB configuration data in the "Device Descriptor" the support files (.inf, .sys and possibly .dll) may be necessary to continue to move forward.

[shuvra1]

Please provide your email Id or something like that so that I mail you. Top design.cysch file in earlier zip

He has used Zadig driver Installer. In his thesis, all code has been given(From last). Please do the needful, I will be highly obliged in my entire life.

[shuvra1]

Can you please set the UART according to main.c /usb protocol.c /usbprotocol.h? 

And in python script wherever required.VID & PID & other stuff. 

And revert me the file as zip as well

Thesis available in internet. 

https://www.google.com/url?sa=t&source=web&rct=j&url=https://www.duo.uio.no/bitstream/handle/10852/8...

He has mentioned all code in his thesis.Its a humble request to you.

Top design.cysch file in earlier zip

[Len_CONSULTRON]

shuvra1,

You have provided, yet again, the same information you have already provided.  The requested original project with the .inf and .sys files to provide the USB communication configuration data and driver ARE NOT PRESENT.  Without these files, I am not able to progress.

I recommend you contact the original author (Olav Bjerke) directly to acquire this information.

[shuvra1]

[shuvra1]

Those are new data from Olav itself,. Top design .cysch file in earlier zip. He has mentioned all code in his thesis that has been attached .Please go through once. He has used zadig driver installer. He wrote in his thesis

[Len_CONSULTRON]

shuvra1,

The pdf from Olav's thesis does indicate VID = 0x04B4 and PID = 0xF232.  (Ref: pgs 143 and 144)

I have downloaded the zadig utility to install the WinUSB driver.  It now does 'complain' about the "Potentiostat" device.

I downloaded Python 3.10 tools.

What do I do next?   I tried to 'run' Potentiostat_GUI.py.  No luck.

 I'm not familiar with Python.

[shuvra1]

Please solve the problem of USBFS. According to.  

select libsub from dropdown not winsb..Please go through the thesis.

Make all python scripts in a folder.  Shift + right click window power shell write

python potentiostst_GUI.py

shuvra1,

I've done all you listed.

I've downloaded PyUSB and tried to install it.

Please do respond it seems like the problem is with USBFS itself.

[shuvra1]

It is able to send communication command data. But unable to generate CSV file. We are in the extremely last stage.

So you say the USBFS does work than ? Wo is unable to generate the CSV file ? I guess that is the PC application which has nothing to do with the embedded software or hardware. CSV file problems often have to do with windows setup such as decimal points/commas, date notation and that kind of windows-related errors. Please be more specific on the CSV error.

Dear @shuvra1 , 

We welcome everyone in need of support with Infineon products in this community.

However, we prioritize bugs/defects in our products, and do not guarantee support on projects developed outside Infineon. There is an emphasis on this especially for students, as it has been brought to our attention by professors that community support has been misused in the past to complete academic projects without putting necessary effort from the students' side. 

Please note the best practice to follow here are to

• Only ask relevant product related queries (with relevant public information) in the community. 
• Always search first (in the community, or outside) for simple queries; as they may have been already answered. If you couldn't find anything, please feel free to ask. 
• Do not ask so many questions in different threads; club whatever you can, and limit the number of threads per day. Always remember, there are also others  that need expert help from our members. 
• Be polite towards the support engineers and community champions helping you. 

The community moderators will remove the threads and ban members from the community if the guidelines are not followed. 

Regards,

Vishnu Nair

Community Manager

shuvra1,

It appears that you didn't find the original Olav Bjerke project files but rather tried to recreate the project from the O.B. thesis pdf.

Where did you get or find the TopDesign.cysch file?   Many of the parameters used in Olav's project are included in the thesis pdf.  However, not all.   This might be the a great part of the issue you are having.

[shuvra1]

Can you mark up kindly those parameters & send me here attach as a clips (25) or you can directly try to recreate that as a expertise. Top design file has been provided by Olav bjerke. Please help me to sort out. You might able to identify what is the issue I am facing & why I am facing.

shuvra1,

I have seen this jpg of an email from OB.   The files you have included appear to be changed from the CY8CKIT-050 that OB used in his thesis to accommodate the CY8CKIT-059 you are using.

I'm concerned if any of the details of the TopDesign.cysch file have been altered from the original.  In particular the parameters of the USBFS component.

I'm still having difficulty getting the python scripts to be configured properly so that this is preventing me from advancing as far as you have.
