CC1310: CC1310 - Sensor Controller Studio Pulse counter

Hi Nirav,

Have you checked the pulse signal using an oscilloscope? Do you see any difference between the Launchpad signal and the one on your PCB?

Also, do you use the same crystals on your PCB, as the ones on the Launchpad?

Regards,

Arthur

We the crystal are the same and we interchanged the Crystal we faced the error

Hi Nirav,

Can you share a schematic, or a section of the schematic with the pulse counting front-end + crystal? A pcb layout section would be interesting as well.

Regards,

Arthur

See the attched image where "Done" pin used for the powered the pulse ICs and the "STATUS LED" Will be used for the countining the pulse.

We write code using Sensor Controller Studio. When testing with the LaunchPad, the counter value updates at one-second intervals, which is as expected. However, on our custom PCB design, we observe a higher counter value than expected.

Interestingly, when we run the code in debug mode, the counter value is correct. But when we run the code in continuous mode (without debugging), we encounter the higher counter issue.

Input PIN : STATUS_LED  

Out PIN for Powered the Pulse ICs : DONE
