software for my plc

sir,

i designed my own plc with avr microcontroller. the problem i facing is the software for that plc with ladder logic can u please give one solution for this.

Hi,

If you really want to program an avr (or pic) in ladder then you should check out http://www.cq.cx/ladder.pl

However, I've tried it a while ago and came to the conclusion that if you want to make optimal use of your avr it's better to use AVR-studio or another C-compiler.

Kind Regards
