Hi all

I get some error messages while trying to use serial port library on attiny85, the problem seems to be the symbol "[" and "]", can anyone help? thanks a lot.

Hi Coding Badly

Thank you for your quick reply, I have this issue before and l fixed it by swap the "ld" file in arduino app content, but not this time, perhaps it's the matter of the Crosspack version? should I try the latest version this time? confused.... btw yes, I am on Mac, thank you so much.

I have no idea. I have had almost no experience with Mac computers.
