Penguin's Circular Buffer Example -- Turning a noisy bell curve into a less noisy bell curve
|
|
||||||
|
|
||||||
Here's an example of using the circular buffer library for sensor data:
|
|
||||||
|
|
||||||
Let's say I have a sensor that gives me temperature at 1khz (using ideals so it is exactly 1khz)
|
|
||||||
If this sensor was only giving me raw analog data, I might want to do some processing on these values
|
|
||||||
so that I can make sure the values are as clean as possible. The more samples we have, the closer we are to the actual value.
|
|
||||||
The faster we gather samples, the closer we get to representing our data in realtime.
|
|
||||||
|
|
||||||
Using the sample rate, I can decide on a sampling window (in seconds) and an OSR (Oversampling Rate). The larger the buffer size, the more memory I need, so
|
|
||||||
it is useful to find a happy medium between a large buffer and clean values.
|
|
||||||
|
|
||||||
A sampling window is the window of time in which we can accept values for an average value. Depending on your application,
|
|
||||||
a sampling window may need to be extremely small or maybe not so small. A rocket going extremely fast using
|
|
||||||
some sensor for real time controls will want an extremely small sampling window as well as a lot of measurements for
|
|
||||||
both clean, near noiseless data and as close to realtime data as possible.
|
|
||||||
|
|
||||||
The sampling windows is usually an engineering requirement given that can match the sampling rate of the sensor with the following:
|
|
||||||
sampling window (in seconds) = 1 / frequency
|
|
||||||
Here, the OSR is simply 1.
|
|
||||||
|
|
||||||
So at 1khz sample rate, let's say I decide I only need a 0.125 second sample window and I want to clean up some noisy data.
|
|
||||||
We can now use this equation:
|
|
||||||
OSR = frequency * sample window (in seconds)
|
|
||||||
|
|
||||||
All of these have ignored real world slowdowns like the time it takes to do math on lower end hardware, interrupts slightly delaying the math, etc
|
|
||||||
Without wanting to do some hard analysis on whatever hardware we're using, I usually take my frequency and half it to ensure timing requirements are met, like so:
|
|
||||||
|
|
||||||
OSR = frequency / 2 * sample window
|
|
||||||
|
|
||||||
Please note: In applications that require real real-time data, this is not a good way of doing things.
