To print the buffer in HEX

Nothing big, thought I will add this for my own reference. This will print the buffer in hex.

1 2 3 4 5 6 7 8 9 10 11

static void print_buffer(unsigned *buffer, int len) { unsigned i = 0; for(i=0;i<len;i++){ if(!(i%8)) printf("\n "); printf(" 0x%02x",buffer[i]); } return; }

You should get an output something like this based on your input

1 2 3

0x74 0x65 0x73 0x74 0x20 0x6c 0x61 0x62 0x65 0x6c 0xa0 0xba 0x9f 0x93 0x6c 0xda 0x31 0x18 0x27 0xa6 0xf7 0x96 0xff 0xd5

Hope this helps someone.
