Fast A/D data logger to SD card using Feather M4 & ADS1262

MCU coding (Python/Arduino IDE) for high-speed data acquisition/logging. Using ADS1262 A/D converter, Feather M4 Express, SD card data storage, AirLift ESP32 Coprocessor for local controls and QC. High sampling rate for high bandwidth (~10-20KHz) EM signals for ~30 second continuous record segments. Data files with GPS time and location headers.

I have semi-working code template; logging files with GPS headers, logs ADC samples but cannot get to samples to record time/rate (sps). Using sample method from vendor libraries (GitHub)

Need help with data sampling method to fastest SD storage rate for 1 channel as first priority, further work to control recording using BLE. All hardware interfaces tested, working, and stacked and wired. "working" sketch attached for considerations, along with ADS1262 data sheet, and sample "recorded file".

Hello, your sample record file is missing, please indicate the data record details. What is the rate at which you need to record the ADC value? GPS stamping rate etc?
