Hi mahmed106,

Hi mahmed106,

As you mentioned correctly, there is no example code for configuring the DA1468x as a slave device. You could define the dg_configI2C_ADAPTER_SLAVE_SUPPORT macro in your configuration file and try to use the ad_i2c_start_slave() API. There is a reference code in the comment of the aforementioned API. Please also see some previous forum threads:
