Is there a list of applicable microcontrollers

[exavier45]

i am wondering if there is a list of microcontrollers that labView drivers can use.  I need to use the microcontroller to accept HEX value that relates to a duty cycle that need to be produced in the microcontroller.  And that signal sent to a 4-wire fan to control the fan speed.  I also need to read this signal back into labVIew to chekc for accuracy.  what drivers will i need to do this and need to do this serially.

so any microcontroller suggestions for this to work would be appreciated.

If a micro-controller has a serial port and it is setup for standard RS-232 communication, then LabVIEW can talk to it. It doesn't matter what the actual micro is at all. The driver that LabVIEW uses for serial communication is called VISA.

You also could use a 6008 or 6009 IO device from NI
This system has a counter on board for timed output and with the analog channels you could read back the info.

i am trying to put a high frequency PWM signal to allow me greater duty cycle range.  On the 6008 and 6009 boards i saw that the outputs had a
software timing refresh rate of 150 hertz.  which is not enough for what i want to do so this is why i decided to go with a microcontroller.

Another question i wnat to be able to check that the signal i am getting from the microcontroller is the same as what i want.  and i need to be able to display this in labView for checking.  as well as sending the signal for the tachometer from the four-wire fan to check for something else.  if i go the microcontroller route is this possible to read in these signals without a DAQ device.

You can get much higher on the 6008/9
I presume that you are using the digital output instead of the counter

Albert,

I was under the impression that the 6008/6009 only had an event counter and not a hardware timed output counter. I think one of my co-workers has one on order so I'll have to check it out when it gets here.

You are completely right Dennis, I was mixing it up with the 6215 board, but that is a quite a bit more expensive.

It is better to go for the Mindstorms package. Especially when the labVIEW toolkit comes out it is a nice microcontroller.
