Hi There,
I have doubt about the sampling frequency set through register of ADS1292R if any one can please help me in this. In my register configuration CONFIG1 DR[2:0] bits set as default 010, and sampling rate of each channel should be 500 SPS. as datasheet states that same data rate for each channel. But when I collect the samples and plot on matlab I get exactly half of the samples on each channel.
I generated the internal test signal (square signal) and save data into files, and plot that data in matlab and I can see that two square pulses appear between 500Hz, I have attached the test signal plot for your information please help me in this.
Whatever sampling rate I set I get exactly half of the signal. For eaxmple if sampling rate is 125 I get around 65Hz (65 samples for one clock) one square pulse.
I also captured both Square and ECG(from simulator) simultaneously. I have my own board interfaced with cc2540. samplig rate is 500SPS.
regards,
Abdul Sattar
