Virtual Peripherals in SX/B

Gold_Daddy

···· I have been working on a project in assembly with eight virtual peripherals running.
I was wondering if "VPs" could be implemented using SX/B with a template·(or without) and avoid using assembly altogether.·
If an SX/B VP template is available,·where would I find it.

······· Thanks for any input and help.

Yes, it's possible, but I don't know that anyone has created a template.

Thanks Jon

Do you think you could elaborate on how to use vp's in SX/B or where I could read more on this specific subject?

Thanks again: GD

Start with the Help file -- the Encoder project uses high-level SX/B in the interrupt; technically this is a VP.

Thanks again Jon

I see what you are talking about.

Now all I have to do is figure out how to use eight or so different ISRs in one program.

I am a novice programmer and understand assembly and basic pretty well (NO C or JAVA) but sometimes the concepts elude me.
I will experiment with what I know and get back to you.

Thanks again: GD

PS anyone else who has used VPs in SX/B , feel free to educate me

In the "PROJECTS" forum is a 16 channel PWM program that I wrote that is a VP.

Thanks Bean,

Just so happens I downloaded your 16 channel pwm before you wrote.
Unfortunately needed some shut eye before I could give it a look-see.
Should be doing so this evening.

Thanks again and keep sending suggestions: GD
