Hello,

I have been trying to find a way to use ldmicro and arp arduino uploader to program my arduino uno. I have been programming ladder logic for years and i prefer that type of programming. I can get the hex file to upload into the arduino but it does nothing. There is definatly something i am missing or this just will not work all together. I just want to make sure i am not wasting my time.

any help would be appreciated,

thanks

This sounds interesting to me, can you explain me how you managed to be able to use ladder logic on arduino? I'm starting to design a new board focused on electricians and our PLC "standard" languages: ladder, contacts, etc...

Thanks in advance

I have been trying to find a way to use ldmicro and arp arduino uploader to program my arduino uno.

It would have been helpful if you had included a link to a description of 'ldmicro'.  According to what I could find it supports some PIC and some AVR processors.  Unfortunately the ATmega328 is not on the list of supported processors so the hex code that you are generating is not correct for your Arduino.  I found the following statement at http://www.cq.cx/dl/ldmicro.txt so perhaps you should follow up on that.

"It would be easy to support more AVR or PIC16 chips, but I do not have
any way to test them. If you need one in particular then contact me and
I will see what I can do."

look here, I too use Ladder logic and want to try this. looks like the problem with 328 has been addressed here,, http://electronics4dogs.blogspot.com/2011/07/ldmicro-and-arduino.html
