Jack,
I found that you had to keep trying different boards using the board manager.? When you select the correct board, it will compile.
You will also need to select the non-USB option, as the USB pin conflicts with the I2S.
Please take the above in the context that I did not get it to work.? I got it to compile and could load an I2C scanner sketch to verify that the board selection did work.? Unfortunately, when installing it into my DE, I got one of the Dupont connectors off by one pin.? That fried all of the components on the i2cbb buss.? I have not recovered from that significant error, as I have had cascading issues.??
The board selection depends on the programmer and the ATtiny85 selection.
For now, the DE is on the shelf waiting for me to settle down to the point that I can dig into the issues yet again.??
Are you sure you need the SWR/Pwr sensor?? For me, I wish I had not tried to add it.? I could be operating the sbitx for the upcoming Field Day.
Look luck.
