How to use I2S interface? #16

I changed MHAL_I2S_TYPE_INTERNAL_LOOPBACK_MODE to MHAL_I2S_TYPE_EXTERNAL_MODE at MT3620_RTApp_FreeRTOS_I2S.

But no signals without MCLK. (TX, FS and SCLK).

You mean there is signal on MCLK, but no signal on TX/FS/SCLK, right? SCLK/FS should be generated by I2S Master, and TX would be generated by MT3620 according to the SCLK signal.

Hi Lawrance-san, Thanks for your information. Sorry. I was wrong. I thought MT3620 supported I2S master.
