In my application, I am using LPC2138 controller and TI's TLV320DAC3100 DAC with built in amplifier to interface audio data.
To implement I2S interface using SPI, some extra hardware circuitry needed which I found from below link:
From above application note, I am able to get following hardware for SPI - I2S interface.
And 5 bit counter is implemented as follows:
My question is above note is specifically for MSP430F Texas controller and I need to interface with NXP LPC2138 controller.
In that case,Is this design logically correct for interfacing I2S on SPI bus? Or LPC associated hardware will differ for such implementation.
