Hi,

I want to buy this robot kit from LAFVIN, they provide everything on their website including the demo code.

I downloaded the code and compiled it and got this error, I don’t know how to fix it.

I think the functions causing the error are in the esp32 source code folder, I searched their with notepad++, and didn’t find the definition of those functions.

  1. The kit website:

When you go to the download page, you’ll find the materials.

  1. I will upload the demo code here:

There are breaking changes in the esp32 code. ledc.... is affected, roll the espressif esp32 boards back to 2.0.17.

Nope, they don’t have that feature on their own website. I think it’s a new growing company but I liked their work + providing all the materials for the kits is a huge plus.

But I can do that on the product page on aliexpress :):+1:

Contact their tech support?

They didn’t respond, even on aliexpress product page.

At least they’re providing the materials so I can start, and I hope the code works with minimal to no issues.
