LDmicro will turn PIC-IO, AVR-IO, AVR-IO-M16 and MOD-IO into PLC

LDMicro created by Jonathan Westhues is nice free program which can turn any PIC or AVR microcontroller in PLC with ladder logic.

The list of the supported devices is:

  • PIC16F628(A), PIC16F88, PIC16F819, PIC16F877(A), PIC16F876(A), PIC16F887, PIC16F886
  • ATmega128, ATmega64, ATmega162, ATmega32, ATmega16, ATmega8

LDmicro allow you to make your ladder schematic then to generate HEX code which does the ladder logic implementation in program code which you program to your AVR or PIC and got the ladder logic functionality.

LDmicro have interfaces in 7 languages, here is nice tutorial how to use it http://cq.cx/ladder-tutorial.pl

Forum is available where you can ask for help if something doesn’t work as expected http://cq.cx/ladder-tutorial.pl

PIC-IO supports PIC16F628 and AVR-IO supports ATMega8 you can use these boards with LDmicro, AVR-IO-M16 and MOD-IO have ATmega16 on it so they are ready to go.

You will need also programmers to load the generated HEX files to the boards, for PIC we recommend PIC-KIT3 and for AVR we recommend AVR-ISP-MK2

LDmicro adds nice functionality to PIC-IO and MOD-IO, AVR-IO, AVR-IO-M16 and offer yet another option to program these boards.
