Hi, If you want to test your program in JAL language, you can take a look at Jalss ( http://pic.flappie.nl/ ) which is the graphical simulator for JAL language. If you are interrested by Melabs PBP basic, assembler or Jal, there is Microdev ( http://sourceforge.net/projects/microdev/ ). This is although a graphical and real time simulator. They can help you to start without a real board. Moreover they are both free. Regards, Nicolas > In any case, you can use MPLAB and MPSIM to learn about PICs and > assembly without having to have a working circuit. And the 'blinking LED' > project still has lasting value if you have limited experience with > building actual hardware. The piclist site has a lot of useful info and > tutorials. Microchip has some code templates. > -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
