A Raspberry Pi Pico with hardwired Ethernet seems like the perfect platform to add web APIs to serial controlled devices. I have a TV which has an RS-232 control interface for power on, changing inputs, etc. A low-power Ethernet-serial bridge device would be ideal to make that interface more usable.
Hackaday made a post that mentioned WIZnet was running a contest to demonstrate products that add hardwired Ethernet to Raspberry Pi Pico boards. The WIZnet
W5100S-EVB-Pico is a Raspberry Pi Pico clone with hardwired Ethernet built right into the board. After learning that this product existed, I realized this was an excellent fit for making a web API for the serial interface on my TV. This repository represents my entry into the WIZnet Ethernet HAT Contest.
I’m Ron from WIZnet HK. Could I post your article to our WIZnet HK instagram account?
BTW, do you have a instagram account that I could tag you?
