555 woes (monostable oscillator)

[MooseFET]

There's a new rule here in the s.e.* hierarchy. Nobody's allowed to say
"Use a Pic" without providing a circuit and a program. ;-)

But - but - but. You don't need a program. All you need is the
oscillator.

For example:

Use a PIC!
Put 2 resistors on an I/O pin..
Here's the code:

INCF FSR, 0x1
INCF INDF, 0x1
MOVLW 0x22
XORWF INDF, 0
BTFSS STATUS, 0x2
GOTO detdone
CALL rndgen
GOTO chgmode

detdone ?
rndgen ?
chgmode ?

Bye.

detdone ?
rndgen ?
chgmode ?

I"m joking around on what Rich wrote..
It's just a code snippet...
detdone was a register that contained error flags.
rndgen was a register that contained a random number.
chgmode was a register that held the control mode. 8 modes.

Unfortunately, nothing to do with the OP trying to make square
waves...

"Monostable oscillator" ....really?.....

LOL!
Noticed that also
I would of got a little more creative..
LDX #$FF;
LDA #$01;
@LOOP:
STA X,$0FFF;
DEC X,
JNE @Loop;
XOR A, $0100;
