Hello

I think there is a little bug in the program example: "CE210291_CapSense_P4_One_Button01.cywrk", but still now I'm not able to fix it 😞

The problem is, that after every start or reset, the Programm needs around 20 seconds to change to the Fast-Scan-Mode.

And if I touch a button from the beginning one (start or reset) the Programm stays forever in Slow-Scan-Mode and not change to the Fast-Scan-Mode.

How can I fix that?

See attached example-Code, I have added LED, Port 2(5) output, named as "interrupt" to see if scan is finished or not.

If blue LED (evakit 4045) is blinking very fast - the Program is in Fast-Mode.

BTW: What is the fastest scan-time we can get with PSoC4000S ? Is it 20mS? (because until now I was not able to tune it faster)

thank you

I can't locate the source code mentioned on the last page of the video transcript:  http://www.cypress.com/file/300846/download  it references this link: www.cypress.com/BLEAndroidApp  which just takes me back to the video webpage.

I just noticed that CySmart is NOT active in the Google Play store.  Can anyone say what is going on?

Thanks

Hi,

I am using CYBLE-214009-EVAL for my development.

In my development, I am using a Android phone (with CySmart APP) to test the device.

It is ok along the development.

In user-trial run, the device cannot connect with iPhone X correctly after several days.

“CYBLE_EVT_GAP_AUTH_FAILED, reason: AUTHENTICATION_TIMEOUT” happens.

HOWEVER, the problem device can connect with other Android phones and even iPhone SE/iPhone 6.

Can anyone help me on the issue?

Is there any way to capture more debug information?

Thanks,

Terry

Hello Cypress.

Below is description of MBR3 design guide.

Document explains that recommended guard sensor thickness is 2mm.

Which part of guard sensor does this description explain?

Does this “thickness” define actual trace thickness(“A” of below figure)?

Or does this “thickness” define width length of guard sensor(“B” of below figure)?

Best Regards.

I have a PSOC 4200 based battery-powered project that goes into deep-sleep and wakes up on external hardware interrupt on pin than goes back to sleep.

Recently I wanted to add a battery monitoring circuit (LED that flashes when battery low) so I set up ADC input and a Global Signal the generates a Watchdog timeout to wake from deep-sleep, read ADC, blink LED and go back to sleep.

What I have found is that this works ok and I get indication of low battery (I am using rechargeable 400mAHr lithium ion). However, if the circuit runs too long when battery low, the software "hangs" and only if I remove and reapply power does it run correctly again.

Can I add a second Global Signal to generate a LVD detection on low power supply and have it generate an interrupt to set a flag. Then when I get condition that Flag is set but battery is OK, I can reboot the code and clear the flag?

Would I just restart my init code or do a full hardware reset?

Thanks

Hello,

I inquired about the SWD pin in the following community.

    https://community.cypress.com/message/164808#164808

This is another inquiry about SWD pin processing.

Q1.

Is it OK to keep the SWD pin open?

Q2.

Does the SWD pin have an internal pull-up like the XRES pin?

Best regards,

Hi Community, 

I finaly ordered a CY8CKIT-042-BLE-A in order to create a mini-quadcopter hoping it won’t take me more than a week (am I too optimistic?)...

In the begining, I've tried using a CY8CKIT-050, but, I didn't even get to wake-up a brushless motor. So it finaly decided me it could be better to afford a CY8CKIT-042-BLE!

Can someone please give me any kind of advices to help me realise that project ? I've never created a quadcopter before even though I'm an electrical engineer (you do have to start, someday... So please don't be cruel...), but it seems to me that I need to have some given cypress' libraries to wake up the brushless motors... Unless they have to be programmed in C language. If that's the case, can I please have a few leads for this codings ? I couldn't find any kind of information for waking up the motors, so I really am in a great need of help... Or can you put me in touch with other engineers familiar with UAV technology who can inspire me towards a good idea?  I am aware that creating a drone is not an easy task, but it is not that which will discourage me...

Hoping to read you soon, 

Sincerely, 

Moumouni
