ADS1299EEGFE-PDK: ADS1299EEGFE-PDK software

Chen-Yang Hung
Prodigy 30 points
Part Number: ADS1299EEGFE-PDK

When I used the software, I found that when I set "samples/CH" to exceed 460000, it would happen that the data could not be read and Retrieving data would take a very long time.(As shown in Figure 1)

The process is very long.(As shown in Figure 2)

I want to know how to solve it.

    Hello Chen,

    Thank you for your post. 

    It sounds like requested sample size is beyond the memory limit on the motherboard for the EVM-PDK (MMB0). 450,000 points is enough for nearly 30 seconds of data. I'm not sure of the exact limit, but I would suggest to reduce the capture size to < 100k samples per channel. This should be enough data for time and frequency domain analysis of the ADC signal chain.

    Regards,

    Ryan

    Thank you Ryan for your reply

    In my project, I must use a Date Rate of more than 10K, continuously sample for 10 minutes, and then output and store the data.
    So I set 16k(sps)*10(min)*60(s)=9600k(samples per channel) and found that this is not feasible (Sample size exceeds memory limit on EVM-PDK motherboard).

    If I reduce the number of samples per channel by using the "CONTINUOUS" measurement method, measure and record to reach 10 minutes, but I found that it cannot be saved when using "CONTINUOUS".

    Is there any solution if I use other communication methods such as SPI, or is there any other solution?

    Hi Chen,

    Unfortunately, we cannot provide support to collect and store such large amounts of data.
