ADS131A04EVM: I want to use a higher sample rate like the 64k Samples per second setting for sampling data on the input of the adc

Greetings,

I have a problem when using higher sample rate, like the 64k SPS. When sampling with the 64k SPS settings, the led d2 or d1 goes out or the console says that there are missing samples. Is there a way to use the 64k SPS settings one way or another ?

Kinds regards,

Sebahaddin

    Hi Sebahaddin,

    Thank you for your post.

    Can you share a screen capture of this error message? Also, what does the data look like after collection? Please share some examples that illustrate the missing samples.

    I believe you can ignore the D1 and D2 LEDs. Per the schematic, these correspond to a bank of unused GPIO pins on the MCU.

    Regards,

    Hello Ryan,

    In the console, I get this message when changing the datarate to 64k SPS:  

    and when I try to sample with this for like 100k samples, It doesn't sample on any of the ADC inputs. After choosing the 64k SPS setting led D1 goes off and I cant send any commands anymore to the device.

    Regards,
