on board I2S interface for TWR-K60f120m

Hi Chung,

i am new to i2s interface,now i want interface of on board two I2S's for TWR-K60F120 using I2S communication for this what can i do first. i think it is possible right. for this communication i made I2S0 as Master and I2S1 as Slave mode. my theme is, to send one byte data (ex, 0x1)from master of I2S0 to Slave of I2S1 and receive the one byte data(ex 0x2) from Slave of I2S1 to Master Slave of I2S0. so for this please if have code please post here.and i have I2S driver code also with this i tried only transmission without slave device initialization for testing of clock line and data line observation on port lines,and the code also posting here so please check it once and inform where i did mistakes in the initialization.

Thanks and Regards,

Padmaja

Pallenna,

Most of our sample code is set the I2S as slave not master. In order for master - slave communication, do you have connection hook up correctly? clk to clk, rx to tx and tx to rx? Also, master and slave clock must sync up.

> i tried only transmission without slave device initialization for testing of clock line

You need slave initialized for proper testing.
