I have a question which is related to the following

e2e.ti.com/.../690282

In above thread, we can refer to sample code for MSP430 which transfer the data between CEC and I2C.

Do we have a sample code to host processor?

Thanks and Best regards,

Hata.

Hello HaTa,

I am not sure if we have host example available. What type of host controller are you looking for?

Cannot provide the device information, but kind of MPU and not MCU

Thanks and Best regards,

Thanks. Assuming this is a TI MPU, I'll move this over to the processors forum since this forum is for MSP430.

Hello Hata,

Do you expect the host processor to be using a particular operating system?

Nick

Hi Nick

Yes. Android OS is in their mind.

Hello,

Could you please share more information about your usecase? I am trying to understand why a host processor would send HDMI signals through the I2C interface, and then a slave processor converts it to CEC. On the AM335x and AM437x devices, the signals from the SoC go directly to the HDMI connectors and the software communicates with the monitor to figure out the resolutions/timing information.

Hi Krunal

I'd like to know it more.

Do you have any documentation which I can imagine the mechanism of it by?

Thanks and Best regards,
