Trinket fuses read 0

Post by Detector73 »

I have 2 trinkets and 3 Si5351 boards. Only 1 trinket works with any 5351 using USB to I2C code in the trinket. I also have an ATtiny with a bootloader. Using avrdude I copied the hex out of the working trinket and installed in the ATtiny.However, the ATtiny still does not work with the Usb to I2C code.
In looking for errors I read the fuses in both trinkets and the AT tiny. They all read 0.
There must be a problem somewhere.
