Compression of log data to extend storage
Since the memory on the board is limited to around 10K entries, is it possible with on board data processing to compress/decrease the resolution of the raw data from for example high frequency accelerometer sampling.
Example, if raw sensor data is 4 bytes per axis?, is it possible to compress down to 1 byte per axis, something like:
acceleration = ((int) x/10000)*10000 + ((int) y/10000)*100+ ((int) z/10000)
or take data from sampling 1-10 and store it as one log entry instead of 10?
