my arduino for the playground adafruit express gets stuck uploading, and is saying that it is not recognizing the ports. <Arduino: 1.8.16 (Windows Store 1.8.51.0) (Windows 10), Board: "Adafruit Circuit Playground"

Sketch uses 6360 bytes (22%) of program storage space. Maximum is 28672 bytes.

Global variables use 351 bytes of dynamic memory.

avrdude done.  Thank you.



the selected serial port 

 does not exist or your board is not connected

  • Not sure how windows works, I'm not using it, but it looks like serial protocol error, board might have been unplugged (physical or software side), in both case, the board is no more on that serial port number. This can occur when too many devices are serialized, consuming too much. Try to dispatch better all your serial devices on all serial ports. Reinitialize hardware numbering & re associate the new serial port in Arduino IDE if needed, then it will be OK.

  • Do you have the correct hardware selected and if like the nano you may have to select a loder.

  • ...for the playground adafruit express gets stuck...

  • avrdude: initialization failed, rc=-1

You appear to have selected the "Classic" rather than "Express" version of the board, which are different things.

  • The classic you have selected uses an AVR ATMega32u4 like you'd find in the Arduino Micro/Leonardo.

  • The "Express" uses an ATSAMD21 chip like an Arduino Zero.

They don't use the same family of microcontroller, bootloader, bootloader protocol, or upload tool. The boards manager package that supports the Class board is completely different from the one that supports the Express board; they are divided support along the lines of the AVR (8-bit) vs SAMD (32-bit arm) chips.

In short, choose the "Express" version of the board after you've gone through setup process for the Express. If you have problems uploading to an Express with the Express board selected, you're likely to see errors that mention bossac, but you're not going to see anything about avrdude.
