Emergency Double Strobe Flip/Flop 2011-07-01

Double flash flip/flop with a PIC12

Notes:

  • Any switching NPN transistor will work.
  • U1 = PIC12Fxxx (675/629/684), check your datasheets to see if others will work with this.

Code

C:
#include <system.h>

#pragma DATA_CONFIG, _MCLRE_OFF&_WDT_OFF&_INTRC_OSC_CLKOUT

	cmcon =7;
	trisio = 0b00001000
	gpio = o;
