disabling all other interrupts was done assuming that after exiting the current INT routine, no other interrupt would occur except RX_INT...

the thing that bother me is that once wheel speed is too slow for POV display, I have the same TImer1 interrupt routine to draw less complex graphics,
so it execute a bit faster,
and then It let me update any parameters I want thru RX_INT.

This is as if the PIC won't even read a PIN status when the Timer1 routine is too busy.

I have tried low/high priority INT, but then my timer was behaving poorly


since I have you here Darrel, is it right to put @INT RETURN in a if condition, to exit an interrupt faster than normal?

Code:
;--- SIGNAL from Hall Fx sensor B ----------------------------
int1_halfxb:
if INTb2_RxInc = 1 then   ; stop INTERUPTS if incoming Rx
  Timr1Start = 0
@   INT_DISABLE   INT0_INT     ; state of interrupts at start
@   INT_DISABLE   INT1_INT     ; state of interrupts at start
@   INT_DISABLE   TMR0_INT     ; state of interrupts at start
@   INT_DISABLE   TMR1_INT     ; state of interrupts at start  
  ledRFpriority = 1
@  INT_RETURN   ; Return to program, (humm that looks clever for instants Ints!!)  
  ; Should add a watch dog for restart
  endif
LEDC1 = 1
cled = 0   
FinishedPixel = 0
redrawLoop = 0
doDoneTxt = 1 ; this will enter txt display first
ledpattern = 0
pattern_repeat = 3

TMR1H = $00  : TMR1L = $00  ; reload preload max value, we want a little delay

pauseus SensorB_offset  ;  for fine tuning

if (NoDisplay = 0) and (INTb2_RxInc = 0) then Timr1Start = 1  ; enable pixel timer 

@  INT_RETURN   	        ; Return to program




code need a bit of cleanup, I will try to make it more readable soon
