interrupt handling faster than if's?

[mbw123]

Would this work as the full code (forgive my ignorannce: I'm a newbie)?

Transmitter:
------------

define HSER_TXSTA 20h
define HSER_BAUD 2400

cmcon = 7

PORTSTATE var Byte
LASTSTATE var Byte
input PORTA.0
input PORTA.1
INput PORTA.2
input PORTA.3

Main:
PORTSTATE = PORTA & $0F
If (PORTSTATE <> LASTSTATE) then
LASTSTATE = PORTSTATE
Hserout [PORTSTATE]
Endif
Pause 10
Goto Main


Receiver
--------

define HSER_CLROERR 1
define HSER_RCSTA 90h
define HSER_BAUD 2400

cmcon = 7
PortState VAR byte
output PORTA.0
output PORTA.1
output PORTA.2
output PORTA.3
low PORTA.0
low PORTA.1
low PORTA.2
low PORTA.3

Main:
Hserin 20,Main, [PortState]
PortState = PortState ^ $0F
PORTA = Portstate
Goto Main

keithdoxey,

what if I wanted to change

"hserout [PORTSTATE]"

to

"hserout [WAIT("~"),PORTSTATE)"

Would that work with the same code?

Thank you.

Hi Mike, sorry for the delay replying, been on holiday for a few days

The above should be "Hserout["~",PORTSTATE]

Wait is only applicable for Hserin.

In your previous post, instead of all the input and output commands just use the following

Transmitter

TRISA = %11111111 ' all pins as inputs

Receiver

TRISA = %11110000 ' A3-A0 as outputs
PORTA = 0 ' turn off all ports

HTH

Thank you very much for the reply.

"Wait is only applicable for Hserin."

Sorry. Stupid mistake by me. I meant

HSERIN [WAIT("~"),PORTSTATE]

Also would that slow down the code a lot?

Thanks.
