Old analog guy needs help with PIC16F57

[yankee]

What code did you use?

[Bruce]

@ device  pic16F57, hs_osc, wdt_off, protect_off

DEFINE OSC 20

Time VAR BYTE

TRISB = 0  ' all outputs
Time = 10

Main:
    PORTB = 0
    PAUSE Time
    PORTB = 255
    PAUSE Time
    Time=Time+10
    IF Time >= 250 THEN Time = 10
    GOTO Main
    
    END

Source and .hex attached.

Note: You can't disable /MCLR on this one, so make sure you have the external pull-up.

OK, when I open your code with the programmer the configuration reads:

0000- 000a

After I install it on the IC, then read it, this is what I get:

0000- 0ffa

I have no idea if this means anything or not.

[Bruce]

Interesting. I opened the same .hex file, and it looks llike the attached.

hs osc, wdt off, protect off.

Sounds like something odd going on with your programmer, or you're not
selecting the correct PIC?

[yankee]

OK, now I'm really confused. My snappy is attached and compared to yours.

[Bruce]

What other options do you have enabled/disabled? See attached.

[yankee]

I compared yours to mine and the only thing that I didn't have checked was "reread file before programming." I made mine match yours, tried again and still nothing. I did a read and the configuration on the IC is still 0000- 0ffa.

When you do a read, what do you get on your configuration?
