Then add a return to the end of those functions because you are supposed to return the number of bytes written. Then find the corresponding part of the Print.cpp file and make the same change.

You need to open up the library file (/usr/share/arduino/hardware/tiny/cores/tiny/Print.h), and in about two places change 'void' to 'size_t'. I got them from Google Code Archive - Long-term storage for Google Code Project Hosting.Īre there any newer libs for the ATTiny available which do not cause any compilation problems ? There seems to be a return type conflict within the libraries used for my Attiny4313. usr/share/arduino/hardware/tiny/cores/tiny/Print.h:73:18: error: overriding ‘virtual void Print::write(const uint8_t*, size_t)’ usr/share/arduino/libraries/Wire/Wire.h:56:20: error: conflicting return type specified for ‘virtual size_t TwoWire::write(const uint8_t*, size_t)’ usr/share/arduino/hardware/tiny/cores/tiny/Print.h:71:18: error: overriding ‘virtual void Print::write(uint8_t)’ usr/share/arduino/libraries/Wire/Wire.h:55:20: error: conflicting return type specified for ‘virtual size_t TwoWire::write(uint8_t)’ In file included from master_reader.cpp:13:0: However, when I try to upload the master_reader sketch from the examples I get the following errors: Then I uploaded the Blink sketch which works fine too.

I want to upload a sketch onto the ATtiny4313 with the Arduino ISP from my Arduino UNO.įirst a uploaded the ISP sketch with no ATtiny4313 connected.
