TMS320F28379D: Can I make a LED matrix display controller?

Vimukthi Pahasara

Part Number: TMS320F28379D


I am planning to design my own HUB75 interface LED matrix display driver with this microcontroller. Is this microcontroller enough for the large size display(1920*1080) with refresh rate up to 50Hz. if so I want to enter pixel data through USB communication and is this microcontroller capable of handling high data speed? I know that this microcontroller support USB 2.0 but does It support the full speed range of USB 2.0?

    Hi Vimukthi,

    The TRM clearly mentions the following: Under Section 23.2

    USB 2.0 full-speed (12 Mbps) operation in host and device modes as well as low-speed (1.5 Mbps)
    operation in host mode

    Regards,

    Hi,

    We do support full speed of USB 2.0.

    However, using a Windows PC as a host running a Visual Studio application, we were only able to achieve 7-8Mbps throughput. In this case the PC was the bottleneck because it was not requesting data fast enough. The F2837x was able to achieve 7-8Mbps with only 30-40% CPU utilization.

    Hope this helps.
