All done now
Read carefully so you don't lock the chip. Any doubts just ask.
ATMega16A Payload Injector Project
P.S: i still need to make PL3 working, haven't take a look at it yet, but shouldn't be hard. I'm doing too many things at the same time xD
I'll let you know when it's done.
EDIT: lol.. forgot to add the bootloader xD Fixed now
Another EDIT: PL3 also adapted to this chip
FINAL EDIT: all done and released now.
