33 * @ingroup EXAMPLES_PERIPH_15XX
34 * <b>Example description</b><br>
35 * This example shows how to configure I2C as a bus slave in interrupt mode using
36 * the I2CS driver.<br>
37 *
38 * This example provides 2 simple (emulated) EEPROMs at different I2C slave
39 * addresses. Both are on the same I2C bus, but the slave controller will be
40 * configured to support 2 slave addresses on the single bus. The emulated
41 * EEPROMs have their memory locations set and read via I2C write and read
42 * operations. Operations can be as little as a byte or continuous until the
43 * master terminates the transfer. The following operations are supported:<br>
44 * - <START> <ADDR><W> Write 16-bit address <STOP><br>
45 * - <START> <ADDR><W> Write 16-bit address <REPEAT START><R> READ READ ... READ <STOP> (unbound read)<br>
46 * - <START> <ADDR><W> Write 16-bit address WRITE WRITE ... WRITE <STOP> (unbound write)<br>
47 * - <START> <ADDR><R> READ READ ... READ <STOP> (unbound read)<br>
48 * Note: Slave address is 0x28.<br>
49 *
50 * Unbound read oeprations have no limit on size and will go as long as the master
51 * requests or sends data. If the end of emulated EEPROM is reached, the EEPROM address
52 * will wrap. All reads and write operations auto-increment. Read operations without a
53 * 16-bit address will use the last incremented address.<br>
54 *
55 * The I2C slave processing is handled entirely in the I2C slave interrupt handler.
56 * This example doesn't use the Chip_I2CS_Xfer() function and implements the slave
57 * support inside the I2C interrupt handler in real-time.<br>
58 *
59 * The example also provides the master interface on the same I2C bus as the slave
60 * to communicate the the emulated EEPROMs without requiring an external I2C master.<br>
61 *
62 * <b>Special connection requirements</b><br>
63 * No special requirements are needed for this example.<br>
