Dear Community,
​
I've been using the MotionMC library on a stm32f401 with quite some succes, but there are 2 functions that remain somewhat mysterious:
char MotionMC_LoadCalFromNVM(unsigned short int datasize, unsigned int *data);
and
char MotionMC_SaveCalInNVM(unsigned short int datasize, unsigned int *data);
​
These functions are used for reading/writing calibration data from/to non-volatile memory (NVM), that much is clear. But there is no real documentation available, and I found no actual implementation examples. I can just implement something that writes/ reads the data, but I have been trying to figure out how they function with library, and that raised a question.
​
The first function tries to load the data from NVM, and gets called during initialization, but I haven't seen the library ever call the save function to write the data. Not even after the calibration quality goes to MMC_CALQSTATUSGOOD.
​
So: when does the function MotionMC_SaveCalInNVM get called? Is there something I forgot to implement / set to get this to work?
​
Thanks for any help / pointers in the right direction!
Léon
