LPC2468 and PWM

[Sergiv]

HI !

 I am using LPC2468 and labview embedded 2010. how to generate a PWM with a period of 20 ms and a pulse duration of 0.005 ms?

Thank you for your support!

It looks like the LPC2468 processor is what is considered a Tier 2 device. This means that the processor is supported by LabVIEW ARM, but the pin outs are not developed for LabVIEW. This article will explain a little more:

You can also try to port the pins yourself by following this link:

After that youwill have to write the proper instructions in order to do a PWM. If you have any questions regarding these, let em know. Thanks,

Thank you for your reply! tier1 = MCB2400. MCB2400 is based on the LPC2468. LPC2468 is not a tier1?

[GoCougs]

So, what tier 1 means is that LabVIEW knows all of the pinouts, and what is available on the evaluation board. You have the same processor which means that LabVIEW has no problems compiling to the processor. What LabVIEW doesn't know is what that processor is connected to, and this is what you would have to program yourself with the instructions found here:

Most of what is in that tutorial I sent to you may not be needed (e.g.porting to RTX kernel) but you will definitely need to port your I/O so that LabVIEW knows what I/O is connected to your processor. I hope that helps!

I could not find PrjAttr.ctl in LabVIEW \ Targets \ Keil \ Embedded \ RealView \ Generic \ LPC2468 \ EIO \

 Could you please describe step by step what to do? Thank you!

From the steps that I gave to you in the link:

• Browse to the LabVIEW\examples\lvemb\EIO\EIO User Plugin Templates\ directory.
• Copy the following files to the LabVIEW\Targets\Keil\Embedded\RealView\LPC3180\EIO directory. They will be used as a template for creating the various plug-in VIs.

The files will not be there until you copy them over to that directory that you have created.

EIO User Plugin copied in 2010 ... LabVIEW \ Targets \ Keil \ Embedded \ RealView \ Generic \ LPC2468 \ eio

but then could not find: Target Editor
where is it?
Thank you!

You need to use the ARM Elemental I/O wizard.
