Part Number: UCD3138
Other Parts Discussed in Thread: USB-TO-GPIO2

Hello,

I am using the UCD138 as a buck controller.

I am using the pmbus_handler() routine that was provided with the training Labs.

Is there an explanation of this firmware utility so that I can change its functionality to use with the GUI?

Hi BatMan,

We do not have a proper documentation of the pmbus_handler() available. However, it is reliable to use. What do you intend on changing in pmbus_handler()? The pmbus_handler() should already work with the GUI. If you want to use a different topology, such as buck, then that should not require changing pmbus_handler(). Pmbus_handler() should only be used to communicate between the UCD and the GUI via the USB-TO-GPIO2 adapter and should not be topology dependent.
