Hello everyone,
I am using a 555 timer to generate a 48HZ square wave with 65% duty cycle. Thats about a 20.8 ms period ( 1/f) with 13ms high and 7.8ms low. That square wave coming out of the 555 timer will be fed into 2 other 555 timers. One timer will generate a pulse width of 1ms, and the other a pulse width of 2ms. This is to control a servo motor by the way.
My questions is:
1) Being that the 555 timer can act only as a non-retriggerable one shot, will it be a problem for me? Or should I have to use a retriggerable one shot like the 74HC123 for this application?
By the way I cannot use a micro-controller for this application, that is why I am using 555 timers instead of generating the desired signals through a controller.
Thanks-
