I have the I2S bus setup correctly via the HCI_VS_Write_CODEC_Config command. I have also put it into loopback mode via HCI_VS_PCM_Loopback_Enable to test it. Now I would like to transmit a known value (from the cc256x I2S bus) so I can test the configuration of the I2S bus on the host processor.
I don't see a HCI command to do this. I figured I could set the I2S TX data register directly via the HCI_VS_Write_Hardware_Register (0xFF01) command. However, I can't find documentation that defines the cc256x hardware register addresses.
Can you provide a the cc256x hardware register addresses, or another means to inject data into the I2S TX?
Thanks,
Layne
