Summary
Configure sampling frequency
Configure microphone
Initialize ES8311 There are two ways of providing Master Clock (MCLK) signal to ES8311 in Slave Mode: 1. From MCLK pin: For flexible scenarios. A clock signal from I2S master is routed to MCLK pin. Its frequency must be defined in clk_cfg->mclk_frequency parameter. 2. From SCLK pin: For simpler scenarios. ES8311 takes its clock from SCK pin. MCLK pin does not have to be connected. In this case, res_in must equal res_out; clk_cfg->mclk_frequency parameter is ignored and MCLK is calculated as MCLK = clk_cfg->sample_frequency * res_out * 2. Not all sampling frequencies are supported in this mode.
Set output volume Volume paramter out of interval will be truncated.
