I'm adding a serial graphics LCD to my project. The help file says to disable interrupts before using serout
but I can't find in the docs the best way to do this.

Can I set OPTION at any time in code?

would something such as this work:

 



[code]

start: 

   OPTION = $86    'int enable, prescalar = 128
 

main:

 

'blah  blah

'blah

'oops need serout

OPTION = $C6      'option reg stays same except bit 6 (RTI) is now 1

serout txpin,baud,"hi"

OPTION = $86     're-enable interrupts

'do stuff

goto main
[/code]right now I'm using the RTCC as a sort of timer.. even if my time periods wind up off by a few seconds because of this,
if it works, I don't mind.. I can adjust the time periods anyway.

 

thanks!
