 		 #111674 - A really hard task !
Responding to: ???'s previous message
If you know 8051, then it is damned hard to downgrade to PIC, because you miss lots of needed powerful instructions.

Also there are lot of pitfalls on the PIC:
E.g. set or clear pins of the same port must be separated by a NOP, otherwise the first intruction was omitted !
And every PIC derivate need a special different register saving sequence on interrupts !
And many more.


I fear ther is no easy way to convert 8051 programs to PIC.
You must throw away the 8051 program and start from scratch with the PIC.
