Chapter 6. I2C API reference

Philips Semiconductors (now NXP Semiconductors) has developed a simple bidirectional 2-wire bus for

efficient inter-IC control. This bus is called the Inter-IC or I2C-bus. Only two bus lines are required: a

serial data line (SDA) and a serial clock line (SCL). Serial, 8-bit oriented, bidirectional data transfers can

be made at up to 100 kbit/s in the Standard-mode, up to 400 kbit/s in the Fast-mode, up to 1 Mbit/s in the

Fast-mode Plus (Fm+), or up to 3.4 Mbit/s in the High-speed mode. [NXP-I2C].

The I2C gateway models of the AnaGate series provides access to a I2C bus via a standard networking.

With the I2C API these I2C gateways can be easily controlled. The programming interface is identical for

all devices and used the network protocol TCP in general.

Following devices can be addresse via the I2C API interface:

• AnaGate I2C

• AnaGate Universal Programmer
