PWM buffered approach

[Fred_3202]

Hi everyone,

I'm new to Labview so forgive me if u ask stupid questions.

I'm trying to make a PWM controller to control fuel injectors with. I have a 6035E board here at the University and i want to use this to test my program with.

I trying to make a program that allows me to define a PWM signal with various duty cycles during 1 full pulse (for instance a high duty cycle for the first ms and then 50% duty cycle for the remainder of the pulse 5ms). So I need a program that allows me to quickly input such profiles. 

Then because injectors pulses operate from a 0.5ms to 7ms range I don't think i can control real-time so i was thinking about a pre-buffered approach. 

Problem is that I don't really have an idea how to start making such a program. Is there anyone who can help me with this.

Many Thanks,

Will this help?

Yeah,

I saw that program a few weeks ago. It's basically what i need but I need to somehow implement a buffer in that program so that i can define a whole PWM profile into the buffer and then when triggered output the whole buffer @ high speed.

Any tips on how i might be able to do that?
