unsigned int k[32]= {0x01, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,

I want to use ECDH to generate a key. I am unable to use dh1() as its showing above error. Please help me to rectify it.

Welcome

The function is declared like this :

static void dh1(uint8_t k[32], uint8_t f[32]);

It expects parameters of type uint8_t not unsigned int, so the obvious solution is to change the data type of your arrays to uint8_t.
