 		 #68069 - RE: ULN2803 Output droping at 3KHz.
Responding to: ???'s previous message
I am using CNY17-3 optocouplers. The configuration of opto is
uC Pin --->Opto Pin2
Opto Pin1---->180 Ohms--->Vcc [ +5V ] [ Supply 1]
Opto Pin4---->Gnd [ Supply 2 ]
Opto Pin5--->1K Ohms--->Vcc [ Supply 2 ]

Microcontroller is supplied power by Supply 1.
ULN2803 is supplied power by Supply2.
