Project Name:$-$

ADC$\_($L$)$CD

Description:$-$ This program reads the Analog voltage from the potentiometer on input $"$AN$0$

$($RA$0)"$ and displays the $10$Bit ADC result $($i$.$e$.0-1023)$ on the first row of an LCD display. It

also displays the calculated Analog Input voltage on the $2^($nd $)$ row of the LCD display.

Add the file "lcd.h$"$ to the Header Files folder and "lcd.c$"$ Source Files folder as sohwn

below to the project in MPLABx:$-$

Include the "lcd.h$"$ within "main.c$"$:$-$

#include $"..$LLCD $()/($lcd$.$h$)"$

Create a macro name for ON and OFF :$-$

E$.$g$.$ #define ON $1$

#define OFF $0$

Setup PORTB pins RB $<mn>7</mn>$:$0>$ as Digital Outputs.

Setup AN$(0)/($R$)$A$0$ pin as an Analog input.

Setup the ADC as follows $($see ADCON$0$ & ADCON$1$ registers on pages$(114)/(115)$ of the

PIC$16$F$188$ Datasheet$)$:$-$

ADCON$0$

$-$ Setup ADCS $<mtext></mtext><mn>1</mn>$:$0>$ bits to select the internal RC

$-$

Create a $16-$bit variable called "adc val", to store the $10-$bit adc result.

Inside a continuous loop, start an ADC conversion by writing to the $"$GO$\_($D$)$ONE$"$ bit.

Wait until the ADC conversion has completed.

Align the $10$bit ade value from ADRESL & ADSREH inside the variable "adc$\_($v$)$al$".$ Call

the function "display bar$($adc$\_($v$)$al$)".$

Calculate the value of vin using the following calculation:$-$

vin $=(($ float $)$ adc$\_($v$)$al $*5)()/()1023$;

Print the values of "ADC$\_($V$)$al$"$ and the calculated "vin" to two decimal places to the

LCD screer ne shown halow.

Add comments to your coade $($marks lost ior no comments$).$

Ensure all code is properly indented $($i$.$e$.$ marks lost for no indentation$).$

Within Proteus, rather than copying the contents of the main.c code from MPLABx since

there are now multiple files, it is eaiser to point to the compiled hex file
