hi Jin jiang,
i am using ICS43434 on MSP432P401R.
As this controller does not have any I2S channel, i am emulating I2S over SPI.
i want to operate ICS43434 in High performance mode at 23Khz, With respective to timing diagram as mentioned in the data sheet as attached, i have understood from SPI i need to supply 64*23 Khz clock(~1.5Mhz).
whether my understanding is correct?
In addition, how to control WS line over SPI MOSI signal when i have a single ICS43434 connected as a left channel?
Thank you,
Maniram
Hi Maniram,
Your understanding on the clock is correct. As for the timing of WS and SCK, you will need to follow what is in the datasheet. There is a LR pin hat controls where the data is output onto the bus. You need to pull the pin to GND for left channel.
Hope this helps.
Kind regards
Jin
Hi Jin,
Thank you for clearing the doubt with respective to the clock.
In my project schematic the WS and LR signals are connected to the GPIO pins, As i am validating the MONO output, can i make both the GPIO PINS(WS,LR) LOW to get the required PCM data?
Thank you,
Maniram
