Hi,
I am currently testing a DAC with I2S input supplied by the nRF52832. But unfortunately no signal is coming out from the DAC, furthermore when reading the error registers on the DAC through i2c I get a clock error which indicates that the clock ratio is not valid. I have discussed this with Texas Instruments audio forum, but they tell me that the clocks are valid and they point out to rather check if the I2S timing from the nRF is correct. (link to Texas forum)
Is the I2S module on the nRF52832 set to follow the I2S timing specifications?(shown in this link) I wasn't able to measure those parameters, because my scope wasn't precise enough :(
The DAC which I am using is the TAS5760L, link to datasheet.
