unable to allocate memory when using waveInOpen for PDA

[Matute]

Hi, I developed a simple program for labview PDA with the objetive of initialize the driver for the waveform device of a Pocket PC (Windows CE 4.2).
It is giving me the error "MMSYSERR_NOMEM", the PDA is 95% free in memory. Why is this happening?, I am working with Labview 7.0. Do i need Labview 7.1 for Pocket PC 2003?
Thanks

Hi Matute,

Here are a couple of suggestions regarding your issue:

1. Upgrading to LabVIEW 7.1 for your PocketPC 2003.
Especially since you are incorporating sound in your application, LabVIEW 7.1 has integrated additional Sound VIs that eliminate the need to make dll calls to the driver.

2. If using LabVIEW 7.0:

• Make sure you have the patch installed
  In LabVIEW, the version should be displayed as LabVIEW 7.0f1.
  Also, you will need the Microsoft eMbedded
  Visual Tools4 (eVT4) to support Pocket PC 2003 devices. 

• Make sure you are Calling External Code in LabVIEW PDA for Pocket PC correctly.

• Example Program attached to illustrate how to call external code using LabVIEW PDA for PocketPC module.

3. Refer to

• MSDN API page for waveInOpen with explanation of function parameters and return/error values.

• MSDN Technical Article Recording and Playing
  Sound with the Waveform Audio Interface

Let me know if you have any further problems.

Thanks kileen. Could you please be more specific about the adittional sound VIs that LabView has incorporated?. Does it have VIs like "sound input","sound output", "snd write waveform", "snd read waveform", etc ? Where can I get more inf. about this sound upgrades?
Thanks

LabVIEW 7.0 requires the f1 patch in order to have PDA support.

Hi Matute,

LabVIEW 7.1 PDA does have the Sound Input and Sound Output VIs that are currently available in ordinary LabVIEW 7.0 (no PDA support), although the Snd Write/Read Waveform VIs are currently not available.

I have attached screenshots of the 2 new sound palettes for the PDA.
