This thing has a LOT of bit packed registers with settings that don’t neatly follow some mathematical formula. So I basically put all the strings from the manual in there and have them dumped out via lookup tables. If anyone has a better method for reading/writing 24bit little endian integers or building pretty hex strings let me know.

FWIW, the tmc.py:FieldHelper() class can be used for this purpose. (Take a look at the top of tmc2130.py for an example of how to define the registers and bits.) Although that class is in the tmc.py file it isn’t specific to the Trinamic devices.
