When I use the example , ..\..\..\..\..\components\libraries\ecc\ecc.c(25): error: #5: cannot open source input file "uECC.h": No such file or directory

How to solve it

[ligang]

Allegedly，the sdk12.1 nees some External software tools。

Now , I want to get the uecc.h.

Can you give me the download link?

The uECC library is an external library that is not a part of the SDK and it must be installed by the user. You can find a step-by-step install guide on this infocenter page.
