UCD3138: is there a program design specification for UCD3138 digital power supply

Part Number: UCD3138
Other Parts Discussed in Thread: UCD3028

Hello.

I am learning the firmware code for your public UCD3138 full-bridge hard-switching power supply.

I was just getting started with the UCD3138 software design.

After I opened the firmware code, I found that there were many source files, header files, and some files that I did not understand.

I would like to ask, how can I learn the firmware code, is there a program design specification? For example, introduce each file type, program design flow, main program structure and so on.

Thank you.

If you can help, be grateful.

The best way to get started with UCD3138 firmware is probably to practice the training labs at:

www.ti.com/.../UCD-TRAINING-LABS

Also if you are interested in certain topology or certain EVM, you can read the user guide that may have some reference to firmware state machine and structure.

Which one of the firmware projects you are looking at?
Do you have any specific questions?

Regards,

hello，
I have learned the training, I found the training is not include the ADC ， PMBus，Timer，UART, only include the DPP and ARM.I don't know if TI will introduce training videos on UCD3138's ADC, PMBus, Timer, UART, etc., and I look forward to it.
I am interested in UCD3138 No.29 hard switch full bridge converter EVM.I have read a description of the UCD3028 Digital Power Supply Software Design. I do not know if there is a similar UCD3138-based digital power supply software design specification.

There are also lots of code examples and explanations in the UCD3138 Technical Reference Manual: www.ti.com/.../sniu028a.pdf

Please also look at the section "A.4 EVM Firmware Introduction" of the EVM-29 user guide:
www.ti.com/.../sluua95.pdf

After reading this and the Technical Reference Manual, and going through the reference code, let us know if you have specific questions.
