Description |
The Serial Peripheral Interface Bus or SPI bus is a synchronous serial data link standard named by Motorola that operates in full duplex mode. Devices communicate in a master/slave mode where the master device initiates the data frame. Multiple slave devices are allowed with individual slave select (chip select) lines using a pin for each device. The attachInterrupt() method activate the SPI interrupt and attaches a function to be executed when the SPI transfer complete interruption is generated during SPI communication. |
