Hi, Hamurabi
Thank you for your interests with W7500.
Do you have WIZwiki-W7500 board?
If you have and you want to know what you can do with it Or just you wanna know how to handle only HC-S04 and LCD…
Like upper answer, I would like to recommend you https://developer.mbed.org/
In it, there is WIZwiki-W7500 as a mbed platform board. https://developer.mbed.org/platforms/?tvend=38
Please refer this page and learn all open code with WIZwiki-W7500 : https://developer.mbed.org/teams/WIZnet/code/
And… here is the example with HC-S04 : https://developer.mbed.org/users/eunkyoungkim/code/catchCats/
I2C LCD : https://developer.mbed.org/users/eunkyoungkim/code/SSD1306_LCD-HelloWorld/
The reason why I tell you mbed.org, In wiznet academy, we offer some lectures with mbed configuration.
But if you want you only get the lib and do with Keil, IAR
If you want to know how to do mbed, please email me. lawrence@wiznet.co.kr
I will send you wiznet academy pdf file
