Hi there,
I have a clock at the receiver and I want it to be synchronized with the transmitter clock. For this reason, I send a short pulse to the receiver so that I know when a clock transition has to start.
For the clocks I'm using the 555 timer. So far I tried experimenting with the reset pin on the 555 IC, however the results depend on the voltage of the capacitor wrt ground at the instant when I pull the reset to ground.
I don't know if it makes sense, but I thought of forcing the voltage at the capacitor to a specific value (Vcc/3) while holding the reset pin to ground. Is this possible, so that when I put the reset pin back to Vcc, the action continues with having (Vcc/3) across the capacitor, hence getting the correct duty cycle?
Thanks
