Title: serial programmer question.... atmegas
Post by: jamort on June 21, 2009, 12:26:12 AM
ok so I like to work on 5 projects or so at the same time.... and I really think its a waste of money buying a bunch of serial programmers to add onto each board... so my question is were i normally use atmega 8  or 16 can I build a board with a socket to put the ic chip in and program it then put it in the actual board that im using... I see tools online about removing the chips but nothing about actually doing something to this extint and hope you'll can understand what I'm saying

i don't see why not

but some projects it may be easier to have the MCU permanent

if you are building a robot for a competition that requires a demonstration and/or has strict guidelines that requires a serial port on the actual bot make sure that you don't cut corners.

some one in a comp i entered did what your tallking about and when they found he did not follow the guidelines they disqualified him

Hi,

Just make one programmer and an ICSP socket on each board.
Something like http://www.evilmadscientist.com/article.php/avrtargetboards (http://www.evilmadscientist.com/article.php/avrtargetboards)

I got tired of wiring ICSP headers on protoboard, I had wires going everywhere that just made everything messy. So I made this chip piggyback thing:

This way I can completely skip the ICSP header, and even make circuits and program them all on bread boards. When I want to program I just put it right on top of the chip and connect the ICSP programmer.

i like the design RAZOR... I was hoping to have something just to stick it in and program it.. normally i only have to program each chip three times so unless its not upright i dont think it will hurt to have it loosely fit as long as it makes connections....

why not just rig up a small board with a regulator, 28 pin socket and the programmer headers?

just hard to understand lol

My advice: use a ZIF (Zero Insertion Force) socket like this one: http://futurlec.com/Sockets/ZIFU28.shtml (http://futurlec.com/Sockets/ZIFU28.shtml)
It's a bit more expensive but you won't regret it.

that looks like the best bet....
