martenkidd In the standard firmware, the I²S interface typically uses the following four pins:
- PCM/IIS CLK
- PCM/IIS IN
- PCM/IIS OUT
- PCM/IIS SYNC
The PCM_MCLK_OUT is not enabled by default in FSC-BT1058. To have the PCM_MCLK_OUT always enabled, a custom firmware modification is required.
If your application needs this feature, please contact our sales team (sales01@feasycom.com)to discuss custom firmware development.
