74HC/HCT166 shift register datasheet, error...?

When you're using LOW or HIGH it make pin automatically as output. BUT i agree TRIS setting is always a safe practice.

DATAI VAR BIT[16]

.

.
.
SHIFTIN SHFTIQ7,_ ' Shift in bits from registers
        SHFTICP,_
        LSBPRE,_
       [DATAI\16]

what about if you change your variable DATAI as follow

DATAI VAR WORD 'it's now 16bits

and then change

FOR LOOP = 0 TO 15 ' Check bits for a high bit
     GOSUB BITNUM
     IF DATAI.0(LOOP) = 1 THEN
     GOSUB HIFND 
     ENDIF
NEXT LOOP

BUT using your code without changing VAR definition (was DATAI VAR BIT[16] )

FOR LOOP = 0 TO 15 ' Check bits for a high bit
     GOSUB BITNUM
     IF DATAI [LOOP] = 1 THEN
     GOSUB HIFND 
     ENDIF
NEXT LOOP

and also i see some RESUME that must be change to RETURN. RESUME are use for interrupts.

for now, it's the only thing i can see. I didn't check the Datasheet for the shift register as now. Wait for your relply on that.

A la prochaine
