ATmega2560/2561 Support?

Postby aek » Wed Oct 05, 2005 1:10 am

It looks like some customers are now using the ATmega2560/2561 parts, which are the first to have a program memor space in excess of 128KB.

The existing Salvo libraries for these parts do not work with these parts due to the different behavior of the RET instruction -- specifically, RET on these parts POPs three bytes, whereas it POPs two on all other AVRs.

We have posted a revised context switcher for Salvo Pro users with ICCAVR to the download area. Until the next release of Salvo for AVR, anyone requiring files for the 2560/2561 should contact us directly and we'll roll a library and/or source code module for you.
