Hi all, Im having a painful time trying to get a 74HC590 to simply count the number of pulses.
My ideas was to use it to count the output from a sensor and then collect the data to the arduino (the arduino isnt fast enough because it running serveral scripts)
The curcuit seems to count like crazy (but too quick to tell if its actually counting up in binary)
So i've rigged this up :
LEDs on output Q0 to Q4 (just for testing) (pins 15,1,2,3) GND (pin 8 ) _RCO (not connected) _MRC (pin 9) to GND CPC (pin11) & CPR (pin 13) tied together to switch to +5v _OE (not connected) Vcc (+5V from arduino)
All power is supplied by the arduino
Have a pinned it out right? Do i need to use a PWM (pulse signal) on th eclocks? I have 555 chips so could set one up if needed.
I dont have a osciliscope and im finding it a pain to sort. Any help would be great. Eventually i want to use the curcuit to count the pulses from a optointeruptor.
Thanks in advance Rob
