to get a certain frequency output I have joined 2 4060 IC's, feeding the
clock input on the first by a crystal oscillator and then taking the last
output into the clock input on the second. based on the crystal I have, my
output from the first IC on pin 3 should be 300 Hz, but feeding this into a
stepper motor control I get one pulse a second or so. Other outputs on the
first IC produce various speeds that "sound" about right (the motor spins
rather than clicking slowly round), so I dunno what I'm missing. How should
the daisy chain be configured? I connected the MR to earth on the second IC
and now the motor stutters unpredictably so maybe that was a wrong step, but
does the second 4060 need any other components?
I was following the suggested layout at the bottom of
http://www.electronics-tutorials.com/devices/555.htm but my crystal is
4.9152Mhz.
Thanks
