Adafruit Trinket M0 - for use with CircuitPython & Arduino IDE

Product Information

bossac -p=/dev/cu.usbmodem14301 -e -w -v -R --offset=0x2000 adafruit-circuitpython-feather_m0_express-3.0.0.bin Digital #1 / A0 - this is connected to PA02 on the ATSAMD21. This pin can be used as a digital I/O with selectable pullup or pulldown, capacitive touch, analog input (use 'A0'), and true analog (10-bit DAC) output. It cannot be used as PWM output.

Adafruit used the same form factor for the original ATtiny85-based Trinket and gave it an upgrade. The Trinket M0 has swapped out the lightweight ATtiny85 for a ATSAMD21E18 powerhouse. It’s just as small, and it’s easier to use, so you can do more. Evening ladies and gents. Bit hesitant calling it a "release"... It is just an Ardudildo sketch with the loader payload added. This was in the dongle development thread. I`ve added Dotstar support and different payloads. Still a WIP. Credits to all in that thread who have been involved in the Trinket M0.The boot.py file is special - the code within it is executed when CircuitPython starts up, either from a hard reset or powering up the board. It is not run on soft reset, for example, if you reload the board from the serial console or the REPL. This is in contrast to the code within code.py, which is executed after CircuitPython is already running. If you are running a MakeCode program on Circuit Playground Express, press the reset button just once to get the CPLAYBOOT drive to show up. Pressing it twice will not work. macOS True analog output on one I/O pin - can be used to play 10-bit quality audio clips in Arduino (CircuitPython does not have storage for audio clips)

Micro B USB connector - We went with the tried and true micro-B USB connector for power and/or USB communication (bootloader, serial, HID, etc). Use with any computer with a standard data/sync cable. You can drive 300 DotStar LEDs with brightness control (set brightness=1.0 in object creation) and 1000 LEDs without. That's because to adjust the brightness we have to dynamically recreate the data-stream each write.PA26 Pin = 26 PA27 Pin = 27 PA28 Pin = 28 PA29 Pin = 29 PA30 Pin = 30 // peripherals: TCC1 channel 0 More info in https://gbatemp.net/threads/build-your-own-dongle-research-and-development-thread.504633/ After the file is copied over, the bootloader will be updated and appear again. The INFO_UF2.TXT file should show the newer version number inside. The first thing we'll do is create the LED object. The NeoPixel object has two required arguments and two optional arguments. You are required to set the pin you're using to drive your NeoPixels and provide the number of pixels you intend to use. You can optionally set brightness and auto_write.
