Example: I2C core library
In this section we present a library of core I2C routines (Listings 23.1 to 23.3). In most cases you will need to add some additional functions to use these files with particular I2C peripherals: we illustrate this process in the examples that follow.
Please note that not all I2C devices use ACKNOWLEDGE / NOT ACKNOWLEDGE
signals (discussed earlier). Similarly, not all devices need a ‘read byte’ facility (PWM and DAC outputs, for example). You can omit these library features by means of these lines at the top of the I2C_Core.C file:
