PIC18F452 Working Problem

In the mikroBasic code which variables hold the prayer times ? I need it to know to send them to LCD.

I think these are the variables
asr = Dec2Bcd(asr)
asr1 = Dec2Bcd(asr1)
marb = Dec2Bcd(marb)
marb1= Dec2Bcd(marb1)
esha = Dec2Bcd(esha)
esha1 = Dec2Bcd(esha1)
 

Why there are two variables for each value ?

Only aser, maghreb and isha ? Where are others ? What does x and x1 contain ?

the final variable is the correct variable that need to be displayed, since each pass through certain rules and formulas more than once

Code: 
    marbtime = dhrtime + durinalarc / 15
    marb1 = marbtime
    marbtime = marbtime - marb1
    marb = floor(marbtime * 60)
    EshaArc = acos((sin(-18 * PI / 180) - sin(Dec1 * PI / 180) * sin(ard * PI / 180)) / (cos(Dec1 * PI / 180) * cos(ard * PI / 180))) * 180 / PI
    eshatime = dhrtime + EshaArc / 15
    esha1 = eshatime
    eshatime = eshatime - esha1
    esha = floor(eshatime * 60)
    fajrtime = dhrtime - EshaArc / 15
    fjr1 = fajrtime
    fajrtime = fajrtime - fjr1
    fjr = floor(fajrtime * 60)
    dhr = Dec2Bcd(dhr)
    dhr1 = Dec2Bcd(dhr1)
    fjr = Dec2Bcd(fjr)
    fjr1 = Dec2Bcd(fjr1)

I don't really know why he used x and x1 arrays
 

Just show me where is

fager
shrouq
zoher

in mikroBasic code and I will modify it to display data on LCD.

Code: 
    dhr = Dec2Bcd(dhr)
    dhr1 = Dec2Bcd(dhr1)
    fjr = Dec2Bcd(fjr)
    fjr1 = Dec2Bcd(fjr1)

These are for fjr and dhr
Dont know why he is using 2 variables, maybe for two digits number!
 

Remove Dec2Bcd conversion code. Use
Code: 
IntToStr()
function to convert the Integer value to string. Use
Code: 
Ltrim()
to trim the leading spaces. Send the string to LCD at required line and column.

Try attached code and Proteus file. I have shown an example by displaying esha. Find out which other variables you want to display and convert them to string and display it.

Here is mikroC PRO PIC and mikroBasic PRO PIC code for DS1307. Use it if you want to display date and time.

I edited the code, and displayed the time for 4 prayers, the problem is there is one hour time shift, in addition to the face that DS isn't showing the correct time!

attached my edited code and image error

RTC is not working properly that is time is not set properly. Search in this forum and also you can use the libstock RTC2 Click example for RTC DS1307. Search in this forum for RTC DS1307. I have done mikroC and Hi-Tech C DS1307 projects and also you will get projects done by others here.
 



I edited the code and it display the time and date now, but the time for the five prayers isn't seem to be effected by the time and date, seems that it doesn't pass time and date values to the formulas.

I'm working on it now, would appreciate if you took a look at it.

No, because there is no code which calculates Prayer times from RTC data.

This is the formulas that are used to calculate prayers time based on RTC data, it exists in the same code I attached above, but it seems that the values are not passed from RTC variables to the method in which these formulas exist

Code: 
 ard = 31.51667
    tol = 34.48333
    farq = 3
    D_ = ((367 * y) - (floor((1.75) * (y + floor((month_ + 9) / 12)))) + floor(275 * (month_ / 9)) + day - 730531.5)
    L = 280.461+0.9856474 * D_
    L1 = L
    L = L - L1
    L1 = L1 mod 360
    L = L1 + L
    M = 357.528 + 0.9856003 * D_
    L1 = M
    M = M - L1
    L1 = L1 mod 360
    M = L1 + M
    Obliquity = 23.439 - 0.0000004 * D_
    Lambda = L + 1.915 * sin(M * PI / 180) + 0.02 * sin(2 * M * PI / 180)
    L1 = Lambda
    Lambda = Lambda - L1
    L1 = L1 mod 360
    Lambda = L1 + Lambda
    Alpha = atan(cos(Obliquity * PI / 180) * tan(Lambda * PI / 180)) * 180/PI
    Alpha = Alpha - (360 * floor(Alpha / 360))
    Alpha = Alpha + 90 * (floor(Lambda / 90) - floor(Alpha / 90))
    ST = 100.46 + 0.985647352 * D_
    L1 = ST
    ST = ST - L1
    L1 = L1 mod 360
    ST = L1 + ST
    Dec1 = asin(sin(Obliquity * PI / 180) * sin(Lambda * PI / 180)) * 180 / PI
    noon = Alpha - ST
    
    if noon >= 0 then
        noon = fabs(noon)
        L1 = fabs(noon)
        noon = noon - L1
        L1 = L1 mod 360
        noon = noon + L1
    else
        noon = fabs(noon)
        L1 = fabs(noon)
        noon = noon - L1
        L1 = L1 mod 360
        noon = noon + L1
        noon = 360 - noon
    end if
    
    utnoon = noon - tol
    dhrtime = (utnoon/15)+farq
    dhr1 = dhrtime
    dhrtime = dhrtime - dhr1
    dhr = floor(dhrtime * 60)
    dhrtime = (utnoon / 15) + 3
    asralt = atan(1 + tan((ard - Dec1) * PI / 180)) * 180 / PI
    asrtime = acos((sin((90 - asralt) * PI / 180) - sin(Dec1 * PI / 180) * sin(ard * PI / 180)) / (cos(Dec1 * PI / 180) * COS(ard * PI / 180))) * 180 / PI
    asrtime = (asrtime / 15) + dhrtime
    asr1 = asrtime
    asrtime = asrtime - asr1
    asr=floor(asrtime * 60)
    durinalarc = acos((sin( - 0.8333 * PI / 180) - sin(Dec1 * PI / 180) * sin(ard * PI / 180)) / (cos(Dec1 * PI / 180) * cos(ard * PI / 180))) * 180 / PI
    shroq = dhrtime - durinalarc / 15

    marbtime = dhrtime + durinalarc / 15
    marb1 = marbtime
    marbtime = marbtime - marb1
    marb = floor(marbtime * 60)
    EshaArc = acos((sin(-18 * PI / 180) - sin(Dec1 * PI / 180) * sin(ard * PI / 180)) / (cos(Dec1 * PI / 180) * cos(ard * PI / 180))) * 180 / PI
    eshatime = dhrtime + EshaArc / 15
    esha1 = eshatime
    eshatime = eshatime - esha1
    esha = floor(eshatime * 60)
    fajrtime = dhrtime - EshaArc / 15
    fjr1 = fajrtime
    fajrtime = fajrtime - fjr1
    fjr = floor(fajrtime * 60)
    'dhr = Dec2Bcd(dhr)
    'dhr1 = Dec2Bcd(dhr1)
    'fjr = Dec2Bcd(fjr)
    'fjr1 = Dec2Bcd(fjr1)
    
    if asr1 > 12 then
        asr1 = asr1 - 12
    end if
    
    if marb1 > 12 then
        marb1 = marb1 - 12
    end if
    
    if esha1 > 12 then
        esha1 = esha1 - 12
    end if
 

See the original mikroBasic code and check if month_, day, year holds raw BCD data from RTC or transformed data. I will also check it.

day and month data from RTC are converted to decimal and sent to the function. Also y always will be 2010. Is it correct or do you want to send year data from RTC ?

I think Transform_Time() function has to be used and convert RTC data to human readable form and then pass day, month, year data to Prayer time calculation function. Try that.
