Library: [sdcard](https://github.com/CoreElectronics/CE-Makerverse-R2R-DAC-MicroPython-Module/blob/736662d4d0bb810c54242e37fda01cbb2b895bb7/sdcard.py)

 ```
from machine import SPI, Pin
import sdcard, uos

spi = SPI(1,sck=Pin(14), mosi=Pin(15), miso=Pin(12))
cs = Pin(13)
sd = sdcard.SDCard(spi, cs)

uos.mount(sd, '/sd')
print(uos.listdir('/sd'))

# Setup sensors here
adc = ADC(0)
with open('/sd/adcData.txt', "w") as f:
    while True:
        x = adc.read_u16() # Replace this line with a sensor reading of your choosing
        t = time.ticks_ms()/1000
        f.write(str(t)) # Write time sample was taken in seconds
        f.write(' ') # A space
        f.write(str(x)) # Write sample data
        f.write('\n') # A new line
        f.flush() # Force writing of buffered data to the SD card
        print(t, x)
        time.sleep_ms(500)
```
