Win32 Concept Related Question Give Proper Answer.

Hi, 

You can check it. I hope this is a suitable answer. Data Received from receiver side will be:

EF, 07, A7, 17 

Explanation:

Data Sent – Data Received

0d – EF

10 – 07

04 – A7

12 – 17

data

0x240d

There are two bytes. Lower byte is 0d and Higher byte is 24.

As we know that data will be sent in nibble format, starting from lower Nibble towards the higher Nibble.

First byte

First lower nibble d will be sent as 0d

And receiver will receive it as 11101111 = EF

Next, Higher nibble 0 will be sent as

00000000 | 00010000 = 00010000 = 0x10

And receiver will receive it as:

00000111 = 07

Second byte

Now moving toward next higher byte which is 24

The lower nibble 4 will be send as 04

And receiver will receive it as 10100111 = A7

Next, Higher Nibble 2 will be sent as:

00000010 | 00010000 = 00010010 = 0x12

And receiver will receive it as:

00010111 = 17
