LPCX54608 / Web Page

acapart — Tue, 28 May 2019 07:11:44 GMT

I'm working on the LPCX54608J512BD208 and I'm trying to handle a web page on it. I noticed that the examples from an SDK (lwip httpsrv) work only for the one who has 180 pins. Where can I get an example for my chip ?

I'm also wondering how to interact with my web page and my chip ? I would like to trigger an actuator from a button in my web page.

Best regards,

Alexis Capart.

Hi,

The LPC54608 SDK includes the LPC54608J512BD208 and LPC54608J512ET180, so the example should work for your device.

Like you mention, I suggest to check the lwip_httpsrv demo application, this demonstrates an HTTPServer on the lwIP TCP/IP stack with bare metal SDK or FreeRTOS.
The user uses an Internet browser to send a request for connection. The board acts as an HTTP server and sends a Web page back to the PC.

In order to modify the web page, you need to modify the index.html (~\middleware\lwip\src\apps\httpd\fs)

Have a great day,
Sol

Hi, thanks for your answer.

When I import the SDK example I can't change the package of the MCU :

I can only change the package when I start a new project (without an SDK examples). I already manage how to modify the web page with the file fsdata.c (cause it doesn't work if I only change the index.html), by the way, I must use a Hex To ASCII converter and it's not convenient, if you have a solution for that it'll be great. My only issue is to communicate between a web page and the micro controller. Do you have an example like a led controller from a web page ?

Best regards,

Alexis.

Hi,

It is possible to change the MCU, please right click on MCU and select the device.

Unfortunately, we don't have an example as you need. You need to take the server example as a base in order to develop your own application,

Have a great day,
Sol
