I would like to measure the frequency of an input on P4.4 using CCU43 in DAVE 4. The CAPTURE app limits the Minimum Frequency to 1 Hz but I would like to measure 0.4 Hz to 30 Hz.
Is there a way to do this please ?
Thank you very much
Aaron

for those low frequencies its better to use the timer app and calculate the frequencies by your own.
I dont know how it could work with the capture app.

Give a try to CCUx_CONFIG APPs.
BTW: We will take your input for a next version of the APP.

Hi Jesus,
Did the 'Min frequency' limit of 1 Hz get fixed in the CAPTURE App please ?
If not, how can I work around this using the CCUx_CONFIG APPs ?
Thanks very much

Hi all,
OK so for anyone looking to measure very low frequencies using the CAPTURE App the 'Min Frequency [Hz]' field within the 'General Settings' tab seems to have no effect.
The 'CAPTURE_GetPeriodInNanoSec' Method has a max nano second count limitation of uint32_t which limits the minimum frequency measurement to 0.23283 Hz.
If you don't need extremely high frequency resolution you can use the 'CAPTURE_GetPeriod' Method instead giving a minimum frequency measurement of 0.00043683.
In my application I have a 1 pulse per rev sensor on a motor so using the ''CAPTURE_GetPeriod' Method I am now able to easily measure down to 1 rpm instead of 14 rpm.
I hope this helps others
