need sample code for adc turnon and conversion to shows on lcd for pic 16f877a

[peter002]

helo everyone. i m trying to use the ad feature of the pic to show the conversion result on the lcd, i using microc pro for programming and the software shows 3 commans in ad header file that are adc_init, adc_read and adc_sample_read

but using these commands i m getting nothing on the lcd
below is the code i tried

sbit lcd_rs at rc0_bit;
sbit lcd_en at rc1_bit;
sbit lcd_d7 at rb7_bit;
sbit lcd_d6 at rb6_bit;
sbit lcd_d5 at rb5_bit;
sbit lcd_d4 at rb4_bit;
sbit lcd_d3 at rb3_bit;
sbit lcd_d2 at rb2_bit;
sbit lcd_d1 at rb1_bit;
sbit lcd_d0 at rb0_bit;

sbit lcd_rs_direction at trisc0_bit;
sbit lcd_en_direction at trisc1_bit;
sbit lcd_d7_direction at trisb7_bit;
sbit lcd_d6_direction at trisb6_bit;
sbit lcd_d5_direction at trisb5_bit;
sbit lcd_d4_direction at trisb4_bit;
sbit lcd_d3_direction at trisb3_bit;
sbit lcd_d2_direction at trisb2_bit;
sbit lcd_d1_direction at trisb1_bit;
sbit lcd_d0_direction at trisb0_bit;

char txt1[]="Mohit";

char txt2[]="Akash anand";

char i;
int x;
void main()
{
lcd_init();
lcd_cmd(_lcd_clear);
lcd_cmd(_lcd_cursor_off);

trisa=0xff;
adc_init();
delay_ms(50);
adcon1=0x00;
adcon0=0b10000000;
go_bit=1;
while(go_bit==1)
{
}

x= adc_get_sample(0);
lcd_out(1,3,"x=");
}
}

lcd working ok, and i know i hav a lot of mistakes in that code, indeed i m an assembler, and in assembly i hav done that successfuly, but i wanna try in c now, plz hlp..
thanc in advance

Why are you using 8 bit LCD code. mikroC PRO PIC comes with 4 bit LCD library. Where did you get the 8 bit LCD library for mikroC PRO PIC ? LCD 8 bit library comes with mikroC not mikroC PRO.

Try this mikroC PRO PIC code.

well, i use 8 bit mode because it has a bit faster speed that 4 bit mode, and even in the 8bit mode the lcd is working fine.. thanx for the code, i m chking it...

your code seems very simple and clean bro, can u plz xplain me the meaning of folowing code lines?? thanx in advance

FloatToStr(adcVal, str);
                    Ltrim(str);

Good Morning,
Your C program seems to have a flaw. You have an uneven number of {} these. That means your program may have compiled but the action is uncertain. The last } looks like an orphan. Where does the program counter go after the last command statement? Try putting a while(1){}; after lcd_out line. Good luck.

FloatToStr() converts floating point value to string for LCD printing. Ltrim() removes the leading spaces in the string.
