Using the two wire interface bus (TWI, often called “I2C”) most devices on the market can be accessed using generic TWI-VIs.
The user must program data and register access of the device manually.
For a few number of devices the ZBrain-SDK offers direct VI support.
- only 100kb standard data rate is supported
- devices on the same TWI bus should share the supply voltage
- no interrupt support
