Hi Everybody,

I am studying methods to measure people's heart rate. It is mentioned in the document that duty cycle is set to 16%. Can anyone explain it? and is it related to hardware? The Radar GUI have 2 options: enable or disable. Can anyone give me suggestions about this (customize the duty cycle in firmware?)

Hi,

Please refer to the Position2Go Software User Manual Section 4.4 Power Saving.
to have enough insight on the duty-cycle feature. Otherwise, duty-cycle mode can be also enabled/disabled through the DUTY_CYCLE_ENABLE defined under the configuration’s project file config.h.

Best Regards,
Montassar.

Hi tinymanta,

Thank you for your answer and sorry for the late response.
I think there was my error about identifying the problem and asking questions.
After doing some experiment with oscillator i have got some information i need. I want to ask you how to change the waiting time between chirps. Simple, the time of 1 chirp is 1ms and I want my device to wait 5ms until the next playback. Where can I handle that problem?

Hi,

To deal only with ADC raw data, please use the D2G_FW Dave project, allowing Raw data acquisition based on Doppler and/ or FMCW modulation (configurable).
In order to change the frame_period_ms, please refer to the config.h file of your project (line42), where the FRAME_PERIOD_ms define (time period of one frame to capture data) is user configurable.

Best Regards,
Montassar.

Hi Montassar,

Thank you for your support. I corrected the signal according to the conditions and got the ADC that I wanted. I will try it with D2G_FW too.

Best Regards,
H.Minh.
