I can use my AVRISPMKII on my win 10 computer with the newest studio7 to program the MEGA328PB device (a "somewhat" recent device).
However I need to do some work at my older win7 setup, which has the last edition of studio 4 installed. I can connect to the ISPII there, but the device selection (device & signature bytes) dropdown selection does not include the MEGA328PB....I'm not sure where these dropdown selections are stored or where/what to upgrade. In studio4 directories I do see an AVRISP-mkii.dat file from 2009..Is this it & is an update avail. The programmer itself has the latest firmware, as downloaded at the insistence of studio 7.
Is it possible to use studio4 with an MKII programmer on a MEGA328PB ?
