I'm a newbie. I've just begun working on a project where I need to measure a distance. I'm planning on using a Sharp GP2Y3A001K0F (Distance Measuring Sensor Unit). I need to be able to convert the voltage output from the Sharp device to a digital signal that the uC can use to calculate a distance value. Next, I wish to control some LEDs that tell whether or not the measurement is in a particular range (e.g. - green = in-range).
1) Are there any examples out there that would expedite my efforts? Incidentally, I need to accomplish a proof of concept by next week (7/20).
2) If there are no examples, are there tutorials that will get me there?
I'm getting closer. I was asked to include an audible indication of distance, with some beeping. What is the method to generate a sine wave in the Kinetis K60N512?
there exist many possibilities
- have part of sine stored in table and in the periodic interrupt send data from table to DAC
- if you are not stand on sine you could use pwm and generate square wave beep.
