Part Number: TMS570LS1227
Other Parts Discussed in Thread: UCD3138, HALCOGEN

Hi,

I want to test my PMBUS project on TMS570LS1227 Hercule Development Board's I2C bus.

For that i want to use UCD3138's Fusion Design GUI and its usb test adaptor(HPA172).

Which steps should i follow?

    The Fusion Design GUI is to support the evaluation and development of power supply solutions based on UCD3xxx digital power controllers.
    You can use HALCoGen to generate I2C driver, and refer to the I2C example in HalCoGen.

    Yes, i used halcogen for creating the i2c bus.

    But now i want to use fusion design gui for the communication, giving commands, watch the variables, check if it response to my commands etc. 

    For example i am making a new connection cable for the TI adapter and HDK to use the GUI. But when i connect the GUI to UCD, click 'Device ID' command and it automaticly find the UCD device. IDK if its gonna be able to find HDK. Should i create a configuration file or something like that? 

    Or will i need to do anything else?

    It seems to me that the UCD31x has basic PMBUS or I2C firmware in ROM to startup PMBUS or I2C communication. 

    You need to program the TMS570LS12x with I2C driver to handle the command from another I2C device. I am not sure if the command from Fusion Design GUI is fully compatible with I2C communication protocol.
