I need to use pic16f877a to display temperature measured from Lm35 sensor and I need to display the data on an LCD 2X16 (lmb162abc-4)
but I don`t know how to program PIC to interface the lCD using proton IDE
can anyone help me Please ?

If there were any books to program PIC using proton IDE I need their names

 

Hi,
If it is possible on your part to use mikroBASIC, take a look at this:

program thermometer452 
 
dim LCD_RS as sbit at RB4_bit 
    LCD_EN as sbit at RB5_bit 
    LCD_D4 as sbit at RB0_bit 
    LCD_D5 as sbit at RB1_bit 
    LCD_D6 as sbit at RB2_bit 
    LCD_D7 as sbit at RB3_bit 
 
    LCD_RS_Direction as sbit at TRISB4_bit 
    LCD_EN_Direction as sbit at TRISB5_bit 
    LCD_D4_Direction as sbit at TRISB0_bit 
    LCD_D5_Direction as sbit at TRISB1_bit 
    LCD_D6_Direction as sbit at TRISB2_bit 
    LCD_D7_Direction as sbit at TRISB3_bit 
 
dim ADCResult as longword 
dim value as word[3] 
dim vstring as string[3] 
 
sub procedure GlobInit 
    TRISB = 0 
    PORTB = 0 
    TRISA = 1 
    ADCON1 = $4E 
    LCD_Init 
    LCD_Cmd(_LCD_CLEAR) 
    LCD_Cmd(_LCD_CURSOR_OFF) 
    LCD_Out(1, 1, "Temp:") 
    LCD_Out(1, 15, "'C") 
end sub 
 
main: 
     GlobInit 
     while true 
           ADCResult = (ADC_Read(0) * 500) >> 10 
           value[0] = ADCResult div 100 
           value[1] = (ADCResult div 10) mod 10 
           value[2] = ADCResult mod 10 
           vstring[0] = value[0] + 48 
           vstring[1] = value[1] + 48 
           vstring[2] = value[2] + 48 
           LCD_Out(1, 10, vstring) 
           delay_ms(50) 
     wend 
end.

I don't know about PROTON books, but mikroElektronika has a free book on programming PICs with mikroBASIC.

Hope this helps.
Tahmid.

 

thanks alot

if U can send me the full project with the circuit digram
