Can an expert in computer science help me with this homework please. That last expert did not include any code which left me still stuck on this homework. I was able to write some code but the code isn$$t working. Can you please include working code and steps to help me complete this homework, thank you.

The IOT board will receive high$-$speed streams of ASCII data using DMA, convert each character received into its two$-$character hex$-$ASCII value, and echo those back to the PC using DMA.

Step $1)$ use some $$magic help$$ from CubeMX to generate initializations for USART$1$ with DMA;

Step $2)$ create a serial loopback program using surcharged functions to handle interrupts;

Step $3)$ convert Step $2$s version to use registered functions, instrumented to count events with the resulting final stage replicating Homework $04$s Problem $3$ operation through the use of DMA.

This is instruction from the last homework assignment $($ homework $4$: problem $3)$

$($This will be an $$instrumented$$ version of Problem $2$ which uses registered callbacks rather than surcharged functions for all operations. Instrumentation will consist of registering all callbacks that are for errors and exceptions as well as those callbacks that are for basic operating requirements.Each error$/$exception callback will increment a counter for that error$/$exception type before returning to the program. For Problem $3,$ use HAL$\_$UART$\_$RegisterCallback$()$ and register all callbacks$).$

This is all you need to know to help me with this assignment.
