How to program Aardvark i2c/spi to control fan speed?

[nhanthanh]

Hi,

i just have Aardvark from total phase and I would like to program in labview to control PWM of 25kHz fan; would you like to help me to have some idea. I am so new to this project.

thanks

Hi nhanthann,

did you read the UserManual for your Aardvark interface?

See chapter 3.6 and 5!

hi GerdW,

if you have any experience, please share or help me for some very first steps.

Best regards,

Hi nhanthanh,

i have no idea how to use,

When you don't know how to handle DLL calls: go through the beginner courses for LabVIEW. Learn that topic, examine the example VIs coming with LabVIEW.

Then create VIs to call the needed DLL functions.

i am very new to program i2c device to make it work as PWM controller.

This would be the last step.

First you need to call DLL functions, in the right way and in the right order.

Then you need to setup a correct communication with your device.

When those two steps are successful, then you can control your PWM generator…
