Converting hex color code format

Projects Programming

Hello,

I am trying to control some addressable LEDs using a web interface hosted by my ESP32. I am stuck on finding a way to convert the color code from HTML color input (ex. #123456) into a long int (ex. 0x123456) for the LEDs to accept. Any suggestions?

Thanks in advance.

Hi,

I just threw an example color code in there, so I'm not sure what color that is. The thing I'm having trouble with is converting the format the number is in.

Welcome,

You can use strtoul with base 16, or sscanf
