    Default GP2 on a 10F202 as output

    I read the whole datasheet of the 10F202 and I did not succeed in finding how to set GP2 as an output.
    When I put a led via a resistor at GP0, GP1 and GP2 only the GP0 and GP1 leds are working the led on GP2 remains off. (not broken).
    See small example.
    What do I forget ??
    Code:
    		'test voor 10f202
			
		@ DEVICE PIC10F202,INTRC_OSC
		@ DEVICE PIC10F202,MCLR_OFF
		@ DEVICE PIC10F202,PROTECT_OFF
		@ DEVICE PIC10F202,WDT_OFF
		
		DEFINE	OSC	4
				
		TRISIO	  = %00000000
		OSCCAL.0  = 0
		
		UIT1	VAR	GPIO.0
		UIT2	VAR	GPIO.1
		UIT3	VAR	GPIO.2
		IN1	VAR	GPIO.3
		
	
		
		

	
BEGIN:
		IF IN1 = 0 Then
		UIT1 = 0
		UIT2 = 1
		UIT3 = 0
		EndIF
		
		IF IN1 = 1 Then
		UIT1 = 1
		UIT2 = 0
		UIT3 = 1
		EndIF
		
		GoTo BEGIN

    10F202 datasheet (DS41239A)....page 21 (Section 4.6) and page 37 (Section 8.0) will give you all the answers you need.

    i'll bet on
    Code:
    OPTION_REG.5=0

    It's not a bug, it's a random feature.

    @ Skimask:
    I read that part. Thats why I put in the programm :OSCCAL.0 = 0

    @ Mister_e:
    You win the price. That helped.
    I read also that the option reg bit 5 should be 0 , but I wrote at that time in my programm OPTION.5 = 0 , and the compile gave me an error. I forgot to type it in the correct way.
    Thanks.
    Regards
    Mat

    yup OPTION.5 won't work unless you decide to redefine it
    Code:
    @OPTION=OPTION_REG
OPTION VAR BYTE EXT
    ' or the simple one
OPTION VAR OPTION_REG
    Doesn't help if you don't know OPTION_REG

    In this case you could still open the filename.ASM file, there you'll have...
    Code:
    R0              		EQU	RAM_START + 000h
R1              		EQU	RAM_START + 002h
R2              		EQU	RAM_START + 004h
FLAGS           		EQU	RAM_START + 006h
R4              		EQU	RAM_START + 007h
R3              		EQU	RAM_START + 008h
GOP             		EQU	RAM_START + 00Ah
OPTION_REG      		EQU	RAM_START + 00Bh
RM1             		EQU	RAM_START + 00Ch
RR1             		EQU	RAM_START + 00Dh
SOFT_STACK_PTR  		EQU	RAM_START + 00Eh
TRISIO          		EQU	RAM_START + 00Fh
SOFT_STACK      		EQU	RAM_START + 010h

    Code?
    What are you reading from the chip ?

    Sound high likely an ICSP problem. Which programmer & Software?

    Did you tried on a Ziff socket? Are your sure your ICSP circuit is properly implemented?

    Cool 10f202

    I am using an epic plus programmer ver.4.22 and picbasicpro ver 2.50. I have a homemade programming adapter. I can read the blank chip "all 0fff" and the calibration register. I can load the hex file that I just read but can not load the hex files I create. I have no problem with other micros, however this is the only micro I just this program adapter with?

    Thank you for your help!

    Default program adapter

    I believe this is correct for the epic programmer?

    @ device pic10f202,mclre_off
    Could be a missing "e" ???

    _MCLRE_ON EQU H'0FFF'

    Are the config options when using MPASM. PM might be different...
