Input problems with 12F629?

[Acetronics2]

Hi, Graham

Good !

1) I wanted to wipe line about " I var " ... but timeout for editing post caught me !!! - seriously - that doesn't change anything to the produced Hex , as it's just a compiler directive ...

2) I also wanted to add

LOW Servo

just before each PULSOUT Command ... BTW ... could you tell us why ?
to understand the "why" ... just plug and unplug the servo plug for 5 or 6 times in a row ... with power ON

and 3) ... CLEAR might much better be after declaring the variables ... no ???

and ... 4) BINARY numbers must be written %01010101 ... for

TRISIO =

Everything told now !

Thanks for straightening me out. You learn something new every day.

I have read this thread several times and looked at the datasheet several time as well. I am having problems with code that has worked fine in the past and suddenly I can not make GPIO.0 and GPIO.3 function as inputs. This is the code I have used in the past. I have added a TRISIO statement and this does not seem to help either. “TRISIO = %11001011”
This code works on GPIO.1 but not on GPIO.0 and GPIO.3. I have used three ICs and continue to have no luck?

#IF __PROCESSOR__ = "12F629"
#DEFINE MCU_FOUND 1
#CONFIG
cfg = _INTRC_OSC_NOCLKOUT ; INTOSC oscillator: I/O function on GP4/OSC2/CLKOUT pin, I/O function on GP5/OSC1/CLKIN
cfg&= _WDT_ON ; WDT enabled
cfg&= _PWRTE_OFF ; PWRT disabled
cfg&= _MCLRE_OFF ; GP3/MCLR pin function is digital I/O, MCLR internally tied to VDD
cfg&= _BODEN_ON ; BOD enabled
cfg&= _CP_ON ; Program Memory code protection is enabled
cfg&= _CPD_OFF ; Data memory code protection is disabled
__CONFIG cfg
#ENDCONFIG
#ENDIF
#IFNDEF MCU_FOUND
#ERROR "No CONFIGs found for [" + __PROCESSOR__ +"]"
#ENDIF

CMCON = 7
SYMBOL LTIN = GPIO.0 'input
SYMBOL RTIN = GPIO.1 'input
SYMBOL LTOUT = GPIO.2 'output
SYMBOL FOURIN = GPIO.3 'input
SYMBOL RTOUT = GPIO.4 'output
SYMBOL PEIZO = GPIO.5 'output

Over:
IF LTIN = 1 THEN HIGH PEIZO
IF LTIN = 0 THEN LOW PEIZO
IF RTIN = 1 THEN HIGH PEIZO
IF RTIN = 0 THEN LOW PEIZO
IF FOURIN = 1 THEN HIGH PEIZO
IF FOURIN = 0 THEN LOW PEIZO

GOTO OVER

Maybe is useful !

I just found my problem. It was these two lines

SYMBOL RTOUT = GPIO.4

SYMBOL PEIZO = GPIO.5

I had changed my board on the last run and forgot to change the pin numbers in the code. The input was working fine it was the output the whole time.My silly mistake

SYMBOL RTOUT = GPIO.5

SYMBOL PEIZO = GPIO.4

I am back up and running thank You for your reply!
