1.2

How to use the STW8110x API

Add the API in your project (STW8110x.c, STW8110x.h, Digital_Bus_interface.h).

Create a file (Digital_Bus_interface.c) with functions to implement according your

master interface.

Include the STW8110x header file (#include “STW8110x.h”) in the file which uses the

API functions.

Use dedicated functions to program the device (see examples in

Section 6).
