i2cMasterDemo Design

This example illustrates how to utilize the Sapphire High-Performance SoC as an I²C master. The program demonstrates the transmission and reception of data, initially with a single byte, and subsequently with a larger chunk of 20 bytes.

By default, the configuration assumes the slave device is set to transmit a 1-byte register address. For 2-byte register addresses, you need to modify the definition of WORD_REG_ADDR to 1.

The design displays these messages in a UART terminal:
