Other Parts Discussed in Thread: AFE4500EVM, AFE4500
Tool/software:
Hi
I'm actually using AFE4500EVM.
I usually collected PPG data at 100Hz sampling rate and I was able to check the data sampled every 0.01 seconds.
However, when I changed the sampling rate such as 10Hz or 500Hz, I found that the data is still stored every 0.01 seconds.
I want to know what I did wrong.
[Configurations in AFE4500_Register_Generation_v3.3.xlsm]
- Global
. ACQ_MODE : PPG
. CONFIG_SIG_ACQ : PPG, low PRF
- PPG_Config
. fPRF_PPG : 10Hz
. STEP_CUNT : 1
- PPG_Phase_Definition
. NUMPHASE_PPG : 3
. Phase1 : Ambient/FIFO data word 1/SAMP time(us) 117/ ...
. Phase2 : LED/FIFO data word 1/SAMP time(us) 117/ ...
. Phase3 : Ambient/FIFO data word 3/SAMP time(us) 117/ ...
