|#68239 - RE: ULN2803 Output droping at 3KHz.|
Responding to: Michael Karas's previous message
Michael the schematic which you have posted is perfectly describing my connections. The only thing is the ULN2803 is connected to optocouplers and which in turn are connected to uC port pins.
I don't have pull ups across ULN2803 outputs at present. Whats value pull up resistors should I use.
Thanks in advance.
