Joe S. I'm using 20mhz xtal. After Define still the same.
OK 20 mhz will not work with the default config statement, to use 20 mhz you must change it or comment it out of the PIC16F627A.INC file located in the PBP Directory. The Default config is set to use XT_OSC and the 20 mhz requires HS_OSC, what it does internaly is to provide the oscillator with more power, as it is needed to run that fast. Study this link : http://www.picbasic.co.uk/forum/showthread.php?t=543 As for the MCLR PIN tie a resistor about 5k ohm from mclr to thr 5v+ supply. To reset the PIC you then momentaraly ground it, OR in the config statement you turn it off and use it as an I/O.

If you do not believe in MAGIC, Consider how currency has value simply by printing it, and is then traded for real assets.

Gold is the money of kings, silver is the money of gentlemen, barter is the money of peasants - but debt is the money of slaves
