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.
