I also need to make the “Arduino due” run in SPI slave mode as opposed to SPI master mode, (The defaults is SPI Master mode). To set the other Arduinos (Uno / Mega) to run in SPI Slave mode you do the following:-
// turn on SPI in slave mode
SPCR |= _BV(SPE);
Alas SPCR is not available on the “Arduino Due” which means I do not know how to set the DUE to run in SPI slave mode.
This is a popular need so any help will be very much appreciated.
Additional information
IDE used: Arduino V1.5.4 (Windows)
Board used: Arduino Due (Programming port)
Source code: Full version of the Arduino code that I am trying to run can be found on this link:-
