Wont show port options on Adafruit Trinket

by dzeldich on Fri Jan 12, 2018 1:27 pm

Hello,
I have a 3.3V Adafruit Trinket and my problem is that I cant upload my code to the board because it wont show me the port options. I selected for the board (Adafruit Trinket 8Mhz) and for the programmer I selected USBtinyISP but I cant even click on the port option.

Do you have any suggestions?
Thanks!

Your operation sounds normal for a Trinket.

Take a look at https://learn.adafruit.com/introducing-trinket?view=all#setting-up-with-arduino-ide

See where it says :
Even though Trinket has a USB connector, it does not have a "Serial Console" capability, so you cannot use Serial to send and receive data to/from a computer! It will not show up as a PORT in the setup menu

Look at Blink example and see instructions:
To upload to your Gemma or Trinket:
1) Select the proper board from the Tools->Board Menu
2) Select USBtinyISP from the Tools->Programmer
3) Plug in the Gemma/Trinket, make sure you see the green LED lit
4) For windows, install the USBtiny drivers
5) Press the button on the Gemma/Trinket - verify you see the red LED pulse. This means it is ready to receive data
6) Click the upload button above within 10 seconds
