Can an expert please Help me with this problem? the last expert did not full help and i wasn't able to complete the code. Please help me with this becuase i am really confused.

Different serial communication methods have different operating characteristics which make direct

translation of software drivers for them difficult. An example of this is I$2$C$,$ which has an interface

protocol superimposed on its low level serial communication.

For this assignment you have received an email identifying as $$your$$ device one of the seven different

I$2$C devices on the B$-$L$475$E$-$IOT$01$A microprocessor board. You are to obtain the device datasheet

and other useful info you can find and implement a program which takes serial commands from the

PC and executes the functions $$V$(),$R$($aa$),$ and $$W$($aadd$)$ outlined below, where:

$$V$()$ is a request to print the device validation values of your device;

$$R$($aa$)$ is a request to read and report the value stored at address $0$xaa$$ of the device,

$$W$($aadd$)$ is a request to write the value $0$xdd$$ at address $0$xaa$$ of the device.

$//$ Function to print device validation values

void printDeviceValidation$()\{$

$//$ Code to retrieve and print validation values from the device

printf$("$Device validation values: $...$

$")$;

$\}$

$//$ Function to read and report value stored at address $\text{'}0$xaa'

void readAddress$($unsigned char address$)\{$

$//$ Code to read data from specified address and report

printf$("$Value at address $0$x$\%$x: $...$

$",$ address$)$;

$\}$

$//$ Function to write value $\text{'}0$xdd$\text{'}$ at address $\text{'}0$xaa'

void writeAddress$($unsigned char address, unsigned char value$)\{$

$//$ Code to write specified value to specified address

printf$("$Writing value $0$x$\%$x to address $0$x$\%$x$...$

$",$ value, address$)$;

$\}$

int main$()\{$

$//$ Sample code demonstrating command execution

$//$ Assume receiving commands from serial interface

$//$ Example command execution:

char command$[10]$;

int address;

int value;

$//$ Assuming command received: V$()$

printDeviceValidation$()$;

$//$ Assuming command received: R$($aa$)$

address $=0$xAA; $//$ Example address

readAddress$($address$)$;

$//$ Assuming command received: W$($aadd$)$

address $=0$xAA; $//$ Example address

value $=0$xDD; $//$ Example value

writeAddress$($address$,$ value$)$;

return $0$;
