Hello all,
This is my first post, i read a few others but couldn't find the answer i needed, and it looks like everyone here has a pretty good opinion on things. I'm trying to use USB-6008/6009 DAQ cards to control the RPM of a electric motor. I want to use the digital output to generate a PWM, but I'm not sure exactly how to control the frequency of the Square Wave I want. So, I have a few questions...
1) Is it even worth using a USB-6008/6009 DAQ card?
- If not, whats the cheapest alternative?
2) I know i have to use the softaware to trigger the output, so I'm limited to how fast the software is going through the itterations, is it possible to get my signal reasonably to 50Hz while still having a descent amount of samples such that I can manipulate the duty cycle?
3) Has someone already done something similar to this and has code to give me a starting point? I'm in a bit of a jam with time . If not, i can try to get something together if it makes it easier for you guys to give me advice.
Thanks so much for you help!
