SCP1000 Series
Interface Options
Communication interface is pre-programmed in the factory and it can be either SPI (Serial Peripheral
Interface) or I
2
C (Inter-Integrated Circuit). The SPI interface is a full duplex 4 wire interface and the
connection between the MCU and SCP1000 is achieved using MOSI, MISO, SCK and CSB. The I
2
C
interface is slave-only half duplex two-wire interface available on SDA and SCL pins.
