Mini Project $[$MODBUS SLAVE$]$

Using the ARM NUCLEO board, implement a MODBUS over RS$232$ SLAVE. There is a temperature

sensor LM$35$ attached to the ARM board on its analog input and a SG$90$ servo motor to a PWM pin of

the ARM board. Implement Function Code $04$ and Code $06$ of the modbus protocol. use QmodMaster to test your implementation. Function code $04$ will be used to read the temperature

and function code $06$ will be used to set the angle of the servo motor.

$($Write the code in embedded c that can achieve the objective of this project.$).$ the code my include the modbus CRC and please provide the steps on how to configure the pins $($A$0$ amd D$9)$ paramemeter such as the channels, prescalers, etc on the ioc.

I will be using the following components;

$1.$ ARM NUCLEO development board specifically STM$32$L$053$R$8$

$2.$ USB to TTL converter $($ CP$2102$ USB to TTL

$3.$ LM$35$ temperature sensor $($PA$0$ or A$5)$

$4.$ SG$90$ Micro Servo motor $($PC$7$ or D$9)$

$5.$ Arduino Jumper cables
