SPI-Slave

Arduino SPI slave mode library

• Change the Arduino/libraries/SPI folder by the folder in this repository.

Function changes:

1. SPI.begin(mode) --> mode: SPI_MASTER or SPI_SLAVE
2. SPI.attachInterrupt(function) --> function is the SPI ISR. When a interrupt occurs it will be called. This function must take no parameters and return nothing.

Other functions act as the standard library.
