NUCLEO-H743ZI2

Hello Everyone!

I think it's a weird question, however, I am new to NUCLEO-H743ZI2.  Actually, I am facing the issue of low-speed data transfer from MCU to PC (LabVIEW). Before, I was using programming and debugging USB ports to transfer data to LabVIEW. However, I was only able to transfer at a maximum of 115200bps (14400 Bytes ps). Although my requirement is 50,000 Bytes per sec. 

Then I found the USB OTG_FS Connector (CN13). However, I am not sure about the maximum speed through which I can transfer data. And what about the Ethernet port (CN14)?

The UART port should be capable of 921600 or more. Increasing baud rate is probably the easiest solution here.

USB FS can transfer around 5 Mbps, but is more complicated to program.

Eithernet faster than USB FS, unsure of the max but at least 10s of Mbps.
