SPI sensor data decoding
Sensor data is regularly communicated with the main microcontroller through multiple SPI
messages. Since not all communications between sensors and the microcontroller contain
data, it is important for the decoder to properly sort the communications and extract only the
targeted data. The solution involves defining specific masking functions, contained within
independent safing records, programmed by the user. The following figures detail the SPI
message decoding methodology and the ensuing comparisons of valid sensor data to the
programmed thresholds.
