Yesterday, I tried to control a stepper motor using the L297 IC driver, but then I realized that I need another IC which could drive high current to the motor, similar to darlington transistor arrays. The ICs are being purchased at the moment for the need of lab experiment taught by my friend.

Oh well, I decided to learn how to generate a simple PWM in PCI-6221 on LabView -as you know I am always new in this, too many functions available, and I am not used to graphical programming-.

I utilized the counter 0 (DevX/ctr0) to turn on a LED (light emitting diode) that it will flicker according to the signal given. For this card the LED is located on PFI 12 (pin number 2).

Here is the front panel, where user can interact with the program: (more…)
