HI !!!
I use electromechanical counter,and he works with 12V DC.Also I use IC driver ULN2804.Eny pinout and counter works diferents than other (If first count 10 impulses,second or ... count another number of impulses.I need help with this problem.
Best regards

HII !!!
Look,my friend.I need make next :
I must have interface with PIC16F84,and also he must connect with my PC.With any terminal program,I need to send decimal number,like 10 or 15 etc. to interface.With interface,I need 8 electrome chanical counters (he works with 12 V DC).For Examples:If I send A10 or another number,PIC must count with first counter 10 impulses.Or If I sent H10, eight counter must count 10 impulses.The A...,B...,C...,D...,E...,F...,G... anh H... is name of counter or his address.
That is my problems and I must find solution for this interface.
Thank you for any help

first you need to know how to communicate with pc using serial port, I have a laptop pc and it has no serial port so I dont know how to use serial port.

but you can search on this foorum,there are lots of examples about it.

you can send A10 or C10 to the pic with serial port, and the pic will select the counter according to the info that you send.

And to understand when the counter finish count, you should find a solution.
Does it informs you when it finish counting?

Yes,I have NOTEBOOK and adapter USB to RS232.You are rihgt.But,First or other counter port out work diferents than another.Any counter received yours decimal number and work counting.In second solution,if I (examples) send to first counter A10 and he started counting,and in next moment I send second A20,he must make sum nad continue counts to finish.Other works like first..
Thank tou for yours help

Thank you for you help.But,I have one question for you.If you send that one led blinks (examples) 15 second.He started,and in moment you send 10 plus.Is led blink countinius blinking 25 second???Is programs make sum like 15+10 seconds.???
Thank you once gain
