| Name |
setBitOrder() |
| Examples |
SPI.setBitorder(LSBFIRST);
|
| 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 setBitOrder() method sets the bit order to use for SPI communication. On Wiring v1 boards the SPI pins are: SS=24, MOSI=25, MISO=26 and SCK=27. On Wiring S board the SPI pins are: SS=20, MOSI=21, MISO=22 and SCK=23. |
| Syntax |

| Parameters |
| bitOrder |
MSBFIRST or LSBFIRST: the bit order to use. MSBFIRST stands for most significant bit first (leftmost bit), LSBFIRST stands for less significant bit first (rightmost bit). |
