Pic10F202 Master clear will not turn off.

Hi,Archangel

Darrel told that because there is no room for vars in RAM once PBP has placed its own vars ...

so, no serious work could be done using PBP ... just Blinking the Led, may be ...

Arch,
just trying to keep cost down because I plan on producing high numbers. And program is going to be super simple. 12 lines tops. Anyone know of a way to strip one byte of ram? Any way of finding out if PBP3 uses the "w" or "f" register? maybe I can load and unload input into that.

Alain,
I hope you are wrong. haha!

I took your code from your first post and it compiled to 92 words
changed to

#CONFIG
    __config _WDT_OFF & _MCLRE_OFF & _CP_OFF
#ENDCONFIG
DEFINE OSC 4
OPTION_REG=%01000000

TRISIO = %00001000

A VAR GPIO.0
B VAR GPIO.1
C VAR GPIO.2
IN VAR GPIO.3


BEGIN:
GPIO = %00000111
pause 1000
GPIO = %00000000
pause 1000
goto BEGIN

it's down to 66 words

if you add "END"
it jumps to 78

To see what your PBP code is doing look at the .lst file, that might help you.
If my poor memory serves me I believe Darrel said PBP Library uses 14 bytes of memory and you have a total of 24 for this chip.

not that wrong ...

yess ... that's short !

seen ?

In PBP, the 10F202 uses PBPPIC12.RAM, which requests 19 bytes of RAM for PBP system use. The 10F200 only has 16 total bytes of RAM available so it looks like it is a no go with PBP unless you want to do a lot of custom stuff.

Have you looked into a 12Fseries instead of using the 10F202?

Quite a bit of functionality added for just a few cents difference.
Something like the 12F1571?

12F1571-I/P (8pin Dip) .64 cents per unit Qty 1-25
1KWord Flash, 128Bytes RAM, (6) I/O Ports, (2/4) 8-Bit/16-Bit Timers, (1) Comparator, (3) 16-Bit PWM, (4) 10-Bit ADC ch

10F202-I/P (8pin Dip) .57 cents per unit Qty 1-25
512W Flash, 24Bytes Ram, (4) I/O Ports, (1) 8-Bit timer

Elusiveinc,
This is what I use for a program to operate a third tail light. It uses a 10F222.
asm
__CONFIG _MCLRE_OFF & _CP_OFF & _WDT_OFF & _IOFSCS_4MHZ
movwf OSCCAL ; load factory osccal value at start-up
bcf OSCCAL,0 ; Set GP2 as I/O pin
ENDASM
