New automatic SPI decoding algorithm

In this paper is presented a new method how to decode SPI signals. The signals are viewed and acquisitioned with an oscilloscope, after that the signals is transferred to the PC through Ethernet interface and decoded with the application using this algorithm. SPI interface is quite commonly used for communication between microchips, because it has a simple protocol. Testing this communication can be done by decoding the SPI signals, which it´s quite an elaborate task to do it manually, this way a simple application which can do this can reduce a lot of time and effort.
