Analysis and development of an optimal algorithm to be used in a device. I developed this Windows application to load in captured raw data from the device so that it could be played back and presented to various algorithm contenders for analysis. After the best-performing algorithm was found it was transferred to the device. The algorithms were developed in C in a portable manner that could be run on Windows and the embedded device unchnanged. The chosen algorithm was then simply copy/pasted to the embedded environment for inclusion in the device.
