LL_Encrypt ()和LL_EXT_Decrypt()函数无法调用？

LL_Encrypt ()和LL_EXT_Decrypt()函数无法调用？编译无法通过。

编译无法通过？ 有没有具体的错误提示呢？

是的，我已添加ll.h头文件，但是编译时依然无法找到LL_Encrypt，这是怎么回事呢，它的函数原形在哪里？

是的，我已在Options->C/C++ Compioler->Preprocessor里面添加ll.h的路径，但是编译时依然无法找到LL_Encrypt，这是怎么回事呢？

Add the following files into your project to call the encryption/decryption APIs defined in ROM.

• rom_crypto.h
• rom_crypto.c

好的，谢谢，我先试试
