Support for new IMU/MAG ISM330DHCX/MMC5983MA from sparkfun

[ladrians]

Hi there, I am trying to calibrate the following Sparkfun IMU/MAG SparkFun 9DoF IMU Breakout - ISM330DHCX, MMC5983MA, the device is not detected, I get the following:

$ RTIMULibCal
RTIMULibCal - using RTIMULib.ini
Settings file RTIMULib.ini loaded
Failed to open SPI bus 0, select 0
Failed to open SPI bus 0, select 1
No IMU detected
Using fusion algorithm RTQF
No IMU found

Devices are detected here

$ sudo i2cdetect -y 1
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:          -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: 30 -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- -- -- -- 6b -- -- -- --
70: -- -- -- -- -- -- -- --

From the hookup-guide there is sample code to be used on an Arduino, I am using a rpi3 with Ubuntu 20.04.

I was hoping you can point me feasibility to add a new device to the list and make it work? Not sure where and what to modify? From the previous link the libraries are here

• ISM330DHCX Arduino Library
• MMC5983MA Arduino Library

thanks in advance, regards
