The only type of accelerometers that are supported are LIS3DH and LIS3DSH.
One possible method of connecting the accelerometer to the Fly-Super8Pro is described in the table below. The image can be used to aid in identification.
These connections are on the Accelerometer header on the board.

Mounting the LIS3DH
The accelerometer should be mounted firmly to the tool. For a bed slinger (such as an ender 3), it should also be possible to mount it to the bed to take readings for the Y axis.
Add the following to board.txt
accelerometer.spiChannel = 3
Your config.g should be modified as below.
M955 P0 C"D.1+D.0" I20
The I (orientation) parameter tells the firmware which of the 24 possible orientations the accelerometer chip is in relative to the printer axes. It is expressed as a 2-digit number.
The first digit specifies which machine direction the Z axis of the accelerometer chip (usually the top face of the chip) faces, as follows: 0 = +X, 1 = +Y, 2 = +Z, 4 = -X, 5 = -Y, 6 = -Z. The second digit expresses which direction the X axis of the accelerometer chip faces, using the same code. The direction of positive X is printed on the circuit board. If the board was mounted in the orientation shown in the above image, with +X of the machine being to the right, Y+ being behind and Z+ being up, the I value would be 54. This document gives information regarding the I value for the new Duet toolboard with accelerometer.
20 is the default orientation if no orientation has been specified.
There is a plugin to view the accelerometer information. It can be activated under Settings -> General -> Built-in Plugins.
It can then be found under Settings -> Machine Specific -> Accelerometer
The accelerometer can be activated using M956
