Part Number: ADS1298ECGFE-PDK
The sampling of ads1298 is not accurate.
I set HR mode and 1k SPS at CONFIG1 but, measured about 930 /sec on a PC.
when I changed register 1k SPS to 500 SPS, it was measured about 420/sec.
What are the factors that can affect the sampling rate?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Tom Hendrick:
Thank you for your answers.
and , I am using the internal clock, and the JP pin is also properly connected.
This figure is marked when DRDY falls from high to low.
As you see, The waveform is visible in 1ms, but it is cut off in the middle.
I don't know what is matter
In reply to Dongjun Lim:
I am trying to receive data from a ADS1298ECGFE (removing the MMB0) with Atmega16 microcontroller.
The problems start to happen when using the RDATAC mode.
I used interrupt that is triggered on the falling edge of the DRDY signal. (1000 SPS)
In the figure below, When DRDY remains LOW for 5ms, the data receive command can not be sent.
Blue Line = MOSI pin
Yellow Line = DRDY pin
Hi, I am Dongjun.
I did not use MMB0.
and I solved the problem of the DRDY signal. The cause was a delay reading the DRDY signal.
As a result, I confirmed that I read about 1004 data per second.
I measured data for 1 sec and 1 min using a 16-bit timer, but I could not read exactly 1000 SPS.
How do I get exactly 1000 data per second.
please help me.
