Of course there are some computer mod's here too.
C programming projects, mostly PC & Linux.

A 12F675 is used with internal oscillator. A led is connected to Vdd and GP4 with a resistor, a 0,1u capacitor is the only other component. This code works with CCS C (http://www.ccsinfo.com/picc.shtml).
#define GP0 PIN_A0
#define GP1 PIN_A1
#define GP2 PIN_A2
#define GP3 PIN_A3
#define GP4 PIN_A4
#define GP5 PIN_A5
#byte OSCCAL = 0x80
OSCCAL = 0x80; // set internal oscillator to mid frequency
set_tris_a( 0b11111101 ); // set GP1 output, all other inputs
