Prerequisites

Can you reproduce the problem reliably?: Yes

Did you check current release notes for known issues?: Yes

If this is not the latest release, have you checked newer releases? NA

Description:

When using the noise waveform, the frequency slider changes the output waveform as measured in the scope software. The amplitude and the offer sliders do not change.

Steps to Reproduce:

  1. Configure the Kitprog with the code (I am using 043 kit/code and Patrick Kane gave me the code before it was updated here.)

  2. Start the scope software. Click on the noise source with the scope and waveform generator connected to each other properly

  3. Select the other waveforms and see that all three sliders work., Selected the noise and see that only the frequency slider works.

Expected Result:
Amplitude, frequency, and off-set should update the out properly.

Actual Result:
Only frequency works

Frequency (1/1, 1/50, 1/100):
EVery time

Build/Commit:

Please specify the release, like 1.4.1. If there is no release, give us the commit for the code you used.

Target:

CY8CKIT-043, firmware, and parts updated to the latest version

Host OS and Version:

Windows 10, PSoC creator 4.4
I am using this kit to do a mini-research project on stochastic resonance using Schmitt triggers, which need a programmable noise source. I realize I can create my own using the custom feature. BTW the students really like it so far. (SJSU, Gavilan, SJCC bay area CCs) Thanks!

Hi Patrick, Thanks for getting back to me. I looked a the TCL software, and it looks like it should work, in that I can not find where the amplitude and offset are turned off somehow. You guys know best though.
Thanks!

Hi Greg,
Yes, I was getting your messages. I did not respond because I am new to GitHub and did not really know the etiquette. Next week is fine. I did start looking on my own and found the PRBS generator used for the noise source. The other waveforms come from .dat files. Interestingly, the noise file has a DC offset Sinc function.
