AM2431: uPP

Hi Veerappan,

Could you please elaborate more about the usecase?

In our project we use AD9364 RF Agile Transceiver, SPI protocol is used to control the AD9364 and for data transmission between AD9364 and microcontroller they use parallel data transmission. This is the block diagram of AD9364

While transferring data from AD9364 to Microcontroller clock is controlled by AD9364. similarly while transferring data from Microcontroller to AD9364 clock is controlled by Microcontroller. So we need a controller to interface this AD9364.

Is this controller support uPP or similar protocol ? Because we need parallel interface for data transmission and also clock is controlled by AD9364 while data is transferred from  AD9364 to Microcontroller.

Hi Veerappan, 

This sounds like a good application for the AM243x Programmable Real-Time Unit (PRU) peripheral cores and I/O. There are a few examples in the AM243x SDK you can reference here: https://software-dl.ti.com/mcu-plus-sdk/esd/AM243X/08_06_00_45/exports/docs/api_guide_am243x/PRU_IO.html 

From the overview: 

The programmable nature of the PRU cores, along with their access to pins, events and all device resources, provides flexibility in implementing fast real-time responses, specialized data handling operations, custom peripheral interfaces, and in offloading tasks from the other processor cores of the device.

Please check out the PRU section of the TRM here: https://www.ti.com/lit/pdf/spruim2. See 6.4 Programmable Real-Time Unit and Industrial Communication Subsystem - Gigabit (PRU_ICSSG). 

Please let me know if that helps for now. 

Thank you.
