Comunicación I2C

Comunicación mediante la interfaz I2C

I2C, o circuito interintegrado, es una interfaz de chip a chip que admite la comunicación de dos cables. Puede conectarse a dispositivos periféricos I2C y leer y escribir en ellos. Cree el objeto de interfaz utilizando la función device con un objeto aardvark o ni845x.

Para utilizar la interfaz I2C, debe tener instalado un adaptador de host Total Phase^® Aardvark I2C/SPI™ o un dispositivo de interfaz I2C/SPI USB-8451 o USB-8452 NI™.
