Arduino to Arduino. Non ISP. Non USB.

-

i tried looking info on while ago, couldn't find looking for..

it may up, can't seem find it, sorry if i'm doubling in fashion.


isp via arduino , good.
but makes me wonder if can standalone?

by mean, no pc / usb / isp. straight ic ic?

this enable bootloders , sketches loaded direct 1 328 straight on via icsp.

i understand sketches etc may large, eeprom or similar required store , call from..

maybe having usr select different sketchs (eg. fuses, bootloader, sketch / b / c.) , lcd or similar usr feedback.


all aside, how 1 go interpreting , converting data pass sketch on ic in fashion?
eg. sending .hex file master 328 slave?

what processes required, or how go converting .hex / .bin etc in understandable format transmit via icsp?


any or info on useful.

thanks in advance.

that sounds lot easy auto programmer: http://www.solderlab.de/index.php/hardware/auto-programmer


there's sketch loading optiboot bootloader atmega328p.
