Technical Reference I2S Clock config section is confusing
Re: Technical Reference I2S Clock config section is confusing
Yes, but none of those start with FUNC, the register layout is different, and you are passing a shift where a value is expected.

It would appear that you were correct.
netted me a 40Mhz clock on GPIO0. The DAC was not working with that clock. The documentation for the DAC indicated that the clock for 256x 44.1kHz ought to be 11.2896Mhz.
I replaced the above with:
and got the desired frequency. The DAC began outputting analog data, seemingly happy with the corrected master clock speed.
I agree that the documentation should be updated to reflect the full bit string required in each configuration.
Code: Select all
PIN_FUNC_SELECT(PIN_CTRL, CLK_OUT1_S);
PIN_FUNC_SELECT(PERIPHS_IO_MUX_GPIO0_U, FUNC_GPIO0_CLK_OUT1);
I replaced the above with:
Code: Select all
REG_WRITE(PIN_CTRL, 0b111111110000);
PIN_FUNC_SELECT(PERIPHS_IO_MUX_GPIO0_U, FUNC_GPIO0_CLK_OUT1);
I agree that the documentation should be updated to reflect the full bit string required in each configuration.
