LAUNCHXL-F28377S: uPP Duplex Mode able?

Part Number: LAUNCHXL-F28377S


Hi Ti-forum,

I have another question about the uPP Modul of F28377S µC. I did a simplex communication between two microcontrollers with uPP. But I need a Duplex communication for my project.

Is the F28377S Microcontroller able to do a duplex mode?

I read the wiki-ti side. Because of this website, I thougt the µC needs other Pins with function uPP for Channel B. Or can I use normal GPIOs to feed the Channel B for Duplex-Mode?

And is it a "half" or "full" Duplex-Mode which uPP is able to do?

If the F28377s isn´t able to do a uPP-Duplex-Mode, can somone call one µC or DSP from TI which is able to do a uPP Duplex Mode.

Many Thanks in advance!!!

Best Regards,

Stefan

    Hi Stefan,

    uPP only supports simplex mode. This is part of the IP feature. You need to consider some other IP (e.g. SPI) for duplex mode.

    Hi Vivek Singh,
    thank you for your answer.

    If uPP only supports simplex mode, why I can choose duplex mode in the settings of uPP? Because of that, I thought that one processor is supports uPP with duplex mode at least.
    At the wiki-side processors.wiki.ti.com/.../Introduction_to_uPP there is a "High-Speed Data Transfer to FPGA or External uPP" figure. At this picture there are lines from DSP to external device from Channel A and from external device to DSP Channel B. Is this simplex-mode too?

    And sorry for this question, but what does IP mean? IP-Core? Interface Peripheral?

    Many thanks in advance again.
    Best regards,
    Stefan
