First time working with I2S on an ARM processor. I am using an LPC4337 (LBGA256) and want to use the NAU8822LYG CODEC.
This codec has;
The UM19503 manual states two kinds of 4-wire operating modes (transmitter mode and receiver mode).
I am very much in doubt how to connect these 5 I2S pins from the CODEC to my processor. (I want to use I2S0).
I assume MCLK and BCLK can be combined. Any help would be welcomed!
Thanks in advance.
MCLK does not belong to the I2S interface definition. See more info to this pin in chapter 8 of the NAU8822 data sheet.
MCLK - master clock for the CODEC device
BCLK - bit clock of the I2S data
FS - frame sync signal
DACIN - data input of the CODEC device
ADCOUT - data output of the CODEC device
Hello and thanks for your answer.
I do have a hard time figuring out the connections from BCLK, FS, DACIN and ADCOUT to the LPC43xx processor. I can see there are many ways of doing 4-wire setups but none of them makes any sense to me and gives answer to which pin goes to BCLK etc.
