We've had a few posts recently along the lines of:-
"Can't program my PICAXE but it still runs the existing program OK."
Well, here's how to make an 08M OTP.
Write your program and download. (don't use pin0 for anything)
Connect pin0 (leg 7) to +12v for at least 10 secs but not much more.
Your program is now locked in safe and secure. It will be quite impossible to overrite it.
The down side.
Output 0 is always high and it runs a little warm.
For sale:-
PICAXE 08M with the following SECURE program:
Serout 2,(254,1)
pause 500
Main:
pulsout 0,10
w0=w0+1
serout 2,N2400,("Count= ",w0)
pause 200
goto main
Runs a little warm but no pulse on output 0.
Counts OK, great for testing AXE033. No worry about losing code.
Any offers accepted.
Seriously, DON'T TRY THIS AT HOME.
