Project description

1. Summary of Key Findings The core of this study is to utilize Ethernet (W5500) to achieve data transmission speeds much faster than the conventional UART communication. Experimental Purpose: To explore the optimal method for transmitting large amounts of data generated from robot control, etc., to a computer in real time (over 20 kHz). [Comparison Results] UART: At standard speed (115,200 baud), the actual data transmission speed is only about 11,520 bytes/s. TCP/UDP: Using the W5500, a speed of over 3,100,000 bits/s was achieved, approximately 33 times faster than UART. Conclusion: The…
