I saw FAQ on Tue, 30 Jun 2009 14:42:41 GMT nitin chaudhary http://tech.groups.yahoo.com/group/booksbybibin/message/1761 http://tech.groups.yahoo.com/group/booksbybibin/message/1761 When you reset the system through command in ponyprog, the reset led should blink only once. For wrong connection reset led will blink more than one ...

I've made a programmer but is not working(don't know if is the uC or the programmer fault) . Sice i can't test if the uC is fried, i want to test if Sun, 28 Jun 2009 12:16:26 GMT Saeed Ahmed http://tech.groups.yahoo.com/group/booksbybibin/message/1758 http://tech.groups.yahoo.com/group/booksbybibin/message/1758 hi sadiq,  first of all i advise to use xr 2206 instead of 555 xr 2206 is more efficient than 555 u can generate sinosidal as well squre wave .i m attaching Sun, 28 Jun 2009 12:15:07 GMT s.holder123@... http://tech.groups.yahoo.com/group/booksbybibin/message/1757 http://tech.groups.yahoo.com/group/booksbybibin/message/1757 Use the PWM timer, you can alter the duty cycle as required.
