mister e i will explain you what i am doing. i download the above code from net and i compiled with mplab(succesfull). i burn the 16f876 and the chip doesn't start.in the same breadboard i made a sample program to test the lcd screen in pbp.it works like a charm.everything is the same exept the programm. If i understand correct my problem is with crystal config.the sample programm that i made has the same configuration bits and works(i didn't write the line a made it manualy from programmer).i am thinking to check now with XT config to see what happends. I use usb programmer from melabs and also i found from my friend the picstart plus and i tried it with mplab with no success.i put the navtex code in microcode studio but i had a lot of errors and i leave it .the diagramm is below if can be help you.i did't made it all ,only the digital circuit i build (pic ,lcd,max232,buttons), the receiver i don't want it now i want to check the decoder first and the lcd screen.Also i am not checking only the crystal with scope , by the programm must give my 500KHz in 12 pin.What else can i do?
