Question: have you been able to communicate over SPI using an Arduino from Simulink?
I'm having a lot of trouble trying to get the Arduino Support for Simulink to communicate over SPI. I've downloaded the Support Package for Simulink and the Support Package comes up in the Simulink library, but no SPI blocks. Even though Mathworks' website says that it should be there. In addition, the SPI examples (arduino_SPI_EEPROM) don't work either when called from MATLAB's command window, but other examples do.
Any help would be appreciated.
P.S. I'm running MATLAB 2015a if that makes any difference.
