Covering the parameters SEL_SMISM, SMISM and FHYST …
↓↓↓ Complete description, time index and links below ↓↓↓

Last time we’ve tried to determine the function/effect of the ORTH_XY and ORTH_SEL parameters – and failed. We’ve also covered the kinda trivial MAPXYZ parameter (link below). Let’s continue our quest in understanding the parameters.

First we improve our MAPXYZ enum. Then we develop a method for reverse (“forward”) engineering the DSP of the chip. With that tool in hand we successfully decipher SEL_SMISM and SMISM. Finally we have another fail understanding FHYST.

00:00 Intro – continuing to understand the configuration
00:41 Housekeeping 1 – true value range of X, Y and Z
02:47 “Forward” engineering – to reverse engineer
10:38 SMISM, SEL_SMISM – according to the datasheet
15:32 Experimenting 1 – effect of SMISM and SEL_SMISM
24:25 Housekeeping 2 – improving the SMISM methods
26:38 FHYST – according to the datasheet
27:52 Experimenting 2 – FHYST doesn’t work as expected
34:53 Wrap up – a teardown before we continue, bye
