some question about programming
hello
im a begginer, i have some questions about constructing a proggramer
is it safe to use the pc power supply 12/5 v. is there a good way to get a steady power supply from the serial port.
where can i find a simple in circuit proggramer for the 16f877 or 16f628
thanks in advance

ICSP = in-circuit serial programming (i think)
connect pin 1 to the pin 4 of the PIC
pin 2 to pin 14 of PIC
pin 3 to GND
pin 4 to pin 13 of PIC
pin 5 to pin 12 of PIC
pin 6 to pin 10 of PIC
