nothing yet. I substituted TRISB=3D255; with TRISB=3D1; (setting as input o= nly=20 the last bit), and put a 220ohm resistor between PORTB0 and ground. The i= =20 use a clip to connect the 5V to PORTB0 and it plays, i disconnect the clip= =20 and it stops again until i connect it again. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
