AVR SPI programmer

This program allows you to access AVR chips Flash memory, EEPROM
and fuses using a SPI relay. This requires drivers that imple-
ment the SPI Relay protocol.

avrspi: first steps After having done my initial handshaking, I thought the rest of the job was only a matter of implementing the protocol, but I was wrong. There were many issues to fix before I could reliably communicate with my 328P, mostly timing. Now, I seem to be able to reliably extract fuse information, but only in batch mode (that is, run "asp$ aspfl@" directly, then running "(spid)" before running the next command). If I try to interact with the chip in a single asp$ session, I sometimes get wrong values (but no sync error! that's worrying...). 2020-08-30 22:01:09 +10:00			`AVR SPI programmer`
