Automatic control and display of Room temperature

[afterdate]

hello to all

could any one help me . i have this circuit
and i want to do the PIC read the signal form the sensor and do compare like if the signal is 20 turn ON the Fan , and if the signal up 20 turn OFF the Fan and all this i want to shown in LCD. i have a code but does't work i know know why? if any one know what's wrong plz tell me. thank you very much
all the best

and i have a code or the program does't work i do't know.

thank you very much

Hi,

Although I do not use PROTON it seems that this is a "PROTON" code and will not compile in PBP.
May be something of this sort may work.

        DEFINE OSC 4
        
        DEFINE ADC_BITS 8 'Number of bits in ADCIN result
        DEFINE ADC_CLOCK 3 'ADC clock source (rc = 3)
        DEFINE ADC_SAMPLEUS 50 'ADC sampling time in microseconds 
       
        DEFINE LCD_DREG PORTB       ' Set LCD Data port
        DEFINE LCD_DBIT 4           ' Set starting Data bit (0 or 4) if 4-bit bus i.e, Portb.4-PORTb.7
        DEFINE LCD_RSREG PORTB      ' Set LCD Register Select port
        DEFINE LCD_RSBIT 2          ' Set LCD Register Select bit i.e, PORTC.5
        DEFINE LCD_EREG PORTB       ' Set LCD Enable port
        DEFINE LCD_EBIT 3           ' Set LCD Enable bit i.e, PORTB.3
        DEFINE LCD_BITS 4           ' Set LCD bus size ot 4 bit Upper Nibble (4 or 8 bits)
        DEFINE LCD_LINES 2          ' Set number of lines on LCD to 4 Lines
        DEFINE LCD_COMMANDUS 2000   ' Set command delay time in us
        DEFINE LCD_DATAUS 50        ' Set data delay time in us
        
        VOLT   VAR BYTE             ' VOLT AS A VARIABLE  

TRISA.0 = 1 ' SETUP PORTA.1 AS AN INPUT
TRISB   = 0 '


Input PORTA.0 
ADCON1 = %10000000 

LCDOUT $FE,1 : PAUSE 100
main: 
ADCIN 0, VOLT
LCDOUT $FE,$80, DEC VOLT , "   "
goto main

It compiles okay and "hex attached"

hello,Dear Sir;
sougata
thank you very much.

could u explan to me more what are u worte.

i want PIC to take signal from the Sensor and do compare and turn ON if the temperatue LOW and turn OFF when the temperature HIGH.and show the temperature in LCD.

and your answer for only anlogue to digital . could u tell me all. and u said i do't no PROTON no problem. do u know how to write the all code without PROTON. i mean same what to write to me.

iam so sorry bec my language is not perfect.

i hope to understand what i mean.

many thanks

all the best

and your answer for only anlogue to digital or not, bec iam no't good in program also iam not good in PROTON and this code from my friend and if u have same code i mean same to write to me . could u tell me all. and u said i do't know PROTON .
do u know how to write the all code without PROTON. i mean same what did u write to me.

Hi there,

Are you new to programming or just trying to use a micro for the first time ? Let me know the compiler version you are using and I shall try to explain.However it is important if the code at all worked for you. That is if you at all got any display.

hello Dear Sir;
sougata

yes this time first time to use PIC program. and i have project call Automatic control and display of Room temperature. and i thing to use PIC and i have my friend tell me use PIC Basic language it's easy. and he give me the code same i put in the first topic.and u give me a code similler my code. and what do u mean which compiler version u mean the program. i have PROTON IDE Lite.
if also in the university MPLAB program.

Excuse me Sir could i speck to u by Email. and my Email ; [email protected]

thank you very much
all the best

Hi,

This forum is for PIC Basic Pro. This forum is located at www.picbasic.org/forum/ .Since I am not a Proton user it is not possible (practical) to comment on code examples. Regarding email, it is not necessary because this forum is full of pros. This forum has helped me a lot to understand the complexities of programming. I hope you would find somebody on the Proton forum to help you out.


Best of Luck

Hi,

The code example that you posted was in Proton PIC Basic and I converted it into PBP ( PicBasicPro).

In this forum we share codes and problems but you have to walk your own way. You may find somebody to give you code examples to sort out problems but you should have the understanding of what you are doing. Otherwise it would be impossible for you to upgrade/maintain/troubleshoot your program. As I have been a hobbyyist I always have the intention to help hobbyist but with a micro you cannot simply expect to do a copy/paste sort of experiment.
Send me what you want to do exactly, what features you want and what PIC you want to use. I will try to post some examples if possible.
