Exercise $3$

Write a C code corresponding to the circuit below to convert three single ended analog signals of the three sensors $($S$1,$ S$2,$ and S$3)$ as follows:

a$-$ The three signals are converted alternatively using software ADC trigger $($i$.$e$.$ S$1,$ S$2,$ S$3,$ S$1,$ S$2,$ S$3,$ S$1,$ S$2,$ S$3,$ and so on$.......)$

b$-$ Take the average of $10$ samples of each signal and assign the values corresponding to $\backslash (\backslash$mathrm$\{$S$\}1,\backslash$mathrm$\{$~S$\}2\backslash ),$ and $53$ to the variables value$1,$ value$2,$ and value $3$ respectively

c$-$ Switch ON the red, green, and bleu LED is the average value of val$1,$ val$2,$ and val$3$ respectively exceeds $2$ Volts.

d$-$ Assume a $16$ bits conversion.
