I would like to implement in simulink an SPI comunication on a beaglebone black in order to read the values provided by 2 encoders, but in the hardware support package for beaglebone is not present the SPI block. It is possible to define a block able to read the SPI bus using simulink in the external mode?

did you happen to make a block using S-function that I could use?

Unfortunately, at this time Simulink does not have blocks for SPI built in to the Simulink Embedded Coder support package for the BeagleBone Black development platform.
As a workaround, you can use S-function builder to access the SPI interface. The MATLAB Support Package for Beaglebone Black ships with the C-source code to access the SPI interface. The C-code is located under the following:
Support Package Root>\R20XXX\toolbox\realtime\targets\beagleboneio\src\server
The following File Exchange submission contains a step by step tutorial on how to develop BeagleBone Black device drivers blocks:
