twi problems on verify

lamontd

Hi

I have spent the last two days trying to load new firmware but

have constantly had twi errors. I found twi.c and twi.h on the web

but the compiler still cannot find the twi.h file. I cannot find where

the define statement for the twi system is in the configuration file

can you help please

Might be a incompatibility of used firmware and arduino ide. Sadly arduino ide has changed it's compiling behaviour over time making it impossible to compile older versions of firmware with latest ide. Using latest ide and firmware version should work. You might need to delete the arduino build directory in appdata/tmp you see while compiling if the error persists.
