Serial UART and Interupts on a 16F87X

[scasale]

Ok, I got off on a different project for a while. Now to pick this up again! Lets see if I can get my head around this and remember where I was at.

Yes, this seems to work! I need to check one other thing before I sign this off. But I left some of my notes at work. So I will check the last thing tomorrow morning.

Can someone answer what the .0 is for or how it behaves in the line:
IF relay = 1 THEN CW = Stat.0 ' Process relay#1
IF relay = 2 THEN CCW = Stat.0 ' Process relay#2

I understand the "stat" part, but not seeing what .0 function is.

Thank you
Scott

Stat VAR BYTE 'relay status ON/OFF variable
8 bits in a byte -- 0 to 7

IF relay = 1 THEN CW = Stat.0 ' Process relay#1
Stat.0 is the first bit of byte Stat

From the PBP manual

4.4. Aliases
VAR can also be used to create an alias (another name) for a variable. This is most useful for accessing the innards of a variable.

fido var dog ' fido is another name for dog
b0 var w0.byte0 ' b0 is the first byte of word w0
b1 var w0.byte1 ' b1 is the second byte of word w0
flea var dog.0 ' flea is bit0 of dog

Ok! It is all good. Thanks to all that helped me get a handle on this. Makes sense, and I see why it did not work early on, and understand what I did wrong.

Thanks,

Scott
