Just to tell that my PSP project is still alive, or should I say beginning
to come out of the coma.  Today I got a little code running, a small main
loop, like:
        Start   TRISE := $17    ; Enable PSP
                TRISA := $00    ; PortA as output
                PIE1 := $80     ; Enable PSP interrupt
                ADCON1 := $07   ; Set PortE as digital I/O
                INTCON := $C0   ; Enable interrupts
        Loop    If  Indata.flag is set
                then  increment counter
                Output counter to PortA
                Clear Indata.flag
                goto loop

and an interrupt routine checking for PSP interrupt and PSP write, then
setting the Indata.flag

The crucial part is to set PortE as digital I/O by setting ADCON1 properly,
otherwise PortE will be inputs for the A/D converter, a relation that was
not clearly stated in the old data sheet I was relying on but is obvious
from the most recent one. (DS30390E - can be downloaded from Microchips
website).

I've tried replacing the RETURNs in my regular code with RETLW $00, like
Randy Rasa suggested, but I havn't got it working yet.  There might still be
something  I have overlooked.

Thank you for you help so far, I'll be back when I know more.

Regards
Michael
