0-10v dc

[naga]

Hi All,
I need a 0-10v Dc control voltage for control an electronic ballast.
using an Op Amp and a PIC PWM output, (16f77,4mhz)
i need to control 0-10v in 10steps with UP and Down Buttons..

Please help..
Thanks.

Try the attached schematic. Apply pwm to Vin. With trail and error adjust pwm to output the disired voltage. Then enter these values in your code.

What code? I think the O/P wants the code written for them...
With that schematic, a digital pot, a voltage divider, an A/D input, and a bit of trickery, a person should be able to hook up a PIC to auto-track/correct the output voltage...
That's a handy little idea to have around...

Ok, fact #1 - I'm no genius...
fact #2 - good luck getting your code to compile and work in MeLabs PicBasicPro (any version)
And...that code you posted...why would it stop for you? There's nothing in there to make it stop!

Thank you very Much, actually i was trying that code in proton,by mistake i pasted.will delete now.
Since you are a senior member of this forum, and you also understood what code i am searching for, Could you pls help me out. i need to adjust the voltage 0-10 with 2 buttons..
Help would be appritiated..
Warm Regards..
