AWR1243: TDA2Px EVM and Fusion Board I2C interface to cascaded AWR1243 reference design

Part Number: AWR1243

Hi,

I've been searching in the Radar SDK v3.03 for the I2C writes that will be sent through the DS90UB960-953 back channel to (what I'm assuming will be) the I2C to SPI bridge needed to interface to the control registers of the AWR1243s on the cascade TI reference design. If I can find that section of code, I can see if it may work for our cascaded design.  Can you let me know what section of code I will find this I2C data write?  Perhaps it's in the TDA code?  I'm looking for low level write commands, basically the I2C address followed by the data bytes being written.

Thanks - Victor
