This was an analog data acquisition project,in addition to the extra features shown below there is the usual project sub-site.
The etch-a-sketch functions are accomplished by building an array or XY sample pairs and writing the array to the hardware buffer of a DAQ running at 100 kHz which is viewed using the XY mode on the oscilloscope.

The basic project came together without many issues so the team looked at ways the program could be extended.
This started with the development of a star function which builds and injects the data array needed to draw a star on the oscilloscope, afterwards a random function was made which would “walk” each data point to a random position from the last point.
Both of these also worked quite well and we still had a little development time left so we implemented the batman equation (including PC sound effect) which received a great response during the presentation.
