But you probably want to do a little more, lets log the temperature from the chip to a file.

Here's the new script

When saved, the Trinket will start saving the temperature once per second to the SD card under the

import adafruit_sdcard

import microcontroller

import busio

import digitalio

import board

import storage

import os

import time

# Use any pin that is not taken by SPI

SD_CS = board.D0

led = digitalio.DigitalInOut(board.D13)

led.direction = digitalio.Direction.OUTPUT

# Connect to the card and mount the filesystem.

spi = busio.SPI(board.SCK, board.MOSI, board.MISO)

cs = digitalio.DigitalInOut(SD_CS)

sdcard = adafruit_sdcard.SDCard(spi, cs)

vfs = storage.VfsFat(sdcard)

storage.mount(vfs, "/sd")

# Use the filesystem as normal! Our files are under /sd

print("Logging temperature to filesystem")

# append to the file!

while True:

# open file for append

with open("/sd/temperature.txt", "a") as f:

led.value = True # turn on LED to indicate we're writing to the file

t = microcontroller.cpu.temperature

print("Temperature = %0.1f" % t)

f.write("%0.1f\n" % t)

led.value = False # turn off LED to indicate we're done

# file is saved

time.sleep(1)
