cannot upload, no TinyISP

by rhartl on Sat Apr 22, 2017 4:59 pm

Have a Pro Trinket 3V 12MHZ connected with FTDI interface set as such on the Arduino IDE running under Windows 10. I needed to switch to 5V logic and I have Pro Trinket 5V 16MHZ processor as well. The first processor was uploading fine before I switched to the 5V now it will not upload and says it cannot find TinyISP and when I switch back to the 3V I have the same problem. Can anyone help me understand and fix the problem? Thanks in advance.

You're using an FTDI cable, so you want to set the board type to Pro Trinket (FTDI). You have it set to Pro Trinket (USB)
