Hello everybody thank you for taking the time to read my question I have about a labview task that I have gotten. I am completly new with the concept of labview and with the help of youtube videos. I have gotten as far as I have on my task. I have pasted my file down below. And any help with be very appreciated with how to continue on this task as I have gotten completly stuck. I have understood the concept with pwm signals but on this task. Please read my task downbelow. And tip on how to continue would be appreciated thanks.
The tasks down below:
Develop a PWM. Light emitting diods (LEDs) can only be used within a very limited range of voltages. Below this range the diode will not work at all, above the voltage, the diod will burn. So its almost a binär state: LED on or LED off. But if you want to have a dimmable LED, you have to run the LED with a PWM. PWM stands for pulse-width-modulation. You switch the LED on and off for a very short periods. Your eye is not fast enough to follow and will see a mean value. A good description can be found in wikipedia. Our PWM will be much slower, so that we can see the change between on and off.
Subtask 1
The basic programm should have the following features:
- A 'numeric control' to set the period length (during one period the LED be switched on and off one time)
- A 'numeric control' where you can set the percentage of the period time the LED should be switched on
- An LED which is turned on and off by the PWM.
- The time in ms of the on and off time are shown as numeric indicators.
Subtask 2
Add a 'numeric indicator' showing the time between each loop in either ticks, milliseconds, or seconds.
