i try to program an attiny85 with an arduino uno. installed the attiny85 (preferences/board manager...) using this source:
selected then the attiny85, clock '8mhz' (not too sure about the clock selection), port 'arduino uno...', programmer 'arduino as Isp'
opened the 'arduino Isp' example patch and if i try to upload it onto the board the error message comes up: 'serial was not declared in this scope'
can anyone help me? Thanks!
