16x2 LCD clock using PROTON ???
« on: November 17, 2009, 06:08:11 PM »


Pano po pagcode niyan using for loop? kasi nung ginawa ko yun blanko lang lumabas and special characters... kaya ginawa ko diyan paisa2x yung code.. bago lang po sa PROTON kaya medyo makulit po.. tatanong ako ng madami :-P

Code: [Select]
Device 16F877A
XTAL 4

LCD_DTPIN = PORTB.4  ' Assigns the Port and Pins that the LCD's DT (data) lines will attach to.  
LCD_RSPIN = PORTB.2  ' Assigns the Port and Pins that the LCD's RS line will attach to.
LCD_ENPIN = PORTB.1  ' Assigns the Port and Pin that the LCD's EN line will attach to.
LCD_INTERFACE = 4    ' Inform the compiler as to whether a 4-line or 8-line interface is required by the LCD.
LCD_LINES = 2        ' Inform the compiler as to how many lines the LCD has.
LCD_TYPE = ALPHA     ' Inform the compiler as to the type of LCD that the PRINT command will output to

ANONG CODE YAN!?!?!?! anong kaguluhan ito! ace ah!
hehehe

gawa ka nang variable... like seconds, minutes and hour.
delay 1000
tas compute mo

seconds = seconds + 1

tapos if > 60
minutes = minutes + 1

and so on...

wait antay tayo nang masters dito... tooot.

another thing is that... it won't be precise... it's better na gamit ka nang external clock source like "clock" or the ds1307.

take note that basic language gamit mo. that simply means that after nyan mag compile magiging C, then assembly pa yan... bka may ibang gawin yung compiler na hindi maging precise yung timing mo. it might work for a WEEK na tama time keeping mo but i think after a MONTH or two... i don't know.

but for a quick and dirty clock. that's one solution.

Ganun po ba? for exact timing pala dapat assembly na lang gamitin ko.. huhuhu.. palipat2x ako ng language.. babalik din pala ako sa assembly.. hay..

some PICmicros have RTC with them. PIC16F877A, meron nito... PIC16F628A, meron din... di ko pa to napag-eexperimentuhan.. pero ang challenge kasi sakin ay yung backup power supply. the RTC will consume low power during power down. yung counter/time will still increment, syempre wala nang display... kapagbumalik naman yung power, ibibgay pa din yung tamang time sa display.

mas challenging, pero prone to error.

mas maganda talga ang gumamit ng DS1307.... may terminal na for a battery lalagyan nalang. mura lang na implementation to... (pero di ko pa din makuhakuha yung driver using hitech!!! waaaaahhhh!!!! ;D ;D ;D)

OR

GPS clock!!! heheh :D
sa GPS clock naman, mas maiging umaadar din yung RTC para kung sakaling may lag sa communication with the satellites, sya na muna ang magbibigay ng time. then in incase magkaerror naman sa RTC, kapagnagresume na yung communication with GPS, makocorrect na din yung time. kapag nagkaGPS clock ako, i would make it such that it will only communicate with the satellites with a given time interval.... say every 5 mins. RTC will do the counting most of the time.

Ganun po ba? for exact timing pala dapat assembly na lang gamitin ko.. huhuhu.. palipat2x ako ng language..

not necessarily...

ang ibig sabihin ni don martin ay mag implement ng  external time keeping device. wag ang MCU mismo... note, eventhough hardware module (RTC module) ang gagamitin mo, MCU do run in sequential order. paisa-isa... kung gagamit ka ng hardware interrupt, maaari pang magkaroon ng delay ang pagsilbi sa interrupt na yun... its like giving the time counting job to other device... wag na sa MCU.

so implement external time keeper... ds1307 would be the cheapest. sa tingin ko..... hehehe ;D

ika nga, these devices are created to be time keepers! so let them be... ;D

So stay with your compiler... wag pa bago-bago... ;D kapag kabisado mo na, lipat ka na.

@Don martin, may available ba nito sa e-gizmo?

A crystal oscillator circuit is built-in between pins T1OSI
(input) and T1OSO (amplifier output). It is enabled by
setting control bit T1OSCEN (T1CON<3>). The oscilla-
tor is a low power oscillator rated up to 200 kHz. It will
continue to run during SLEEP. It is primarily intended
for use with a 32 kHz crystal. Table 6-1 shows the
capacitor selection for the Timer1 oscillator.
The Timer1 oscillator is identical to the LP oscillator.
The user must provide a software time delay to ensure
proper oscillator start-up.

eh meron naman pala nito... pero paano battery management sir marce? or power down nang machine?

Di ako PIC user, pero I believe i can make an educated guess:

- Enable the hardware interrupt of the timer driven by the 32kHz source.
- Put the MCU in SLEEP Mode or equivalent low power standby mode while it is powered from backup batteries.
- The MCU is awaken for a brief moment everytime an RTC interrupt occurs. This is the period where your RTC interrupt routine does its timekeeping job.
- And then, the MCU is put into sleep mode again.

The average power consumed by the MCU will be very low, allowing it to run on backup batteries for months or even years.

Di ako PIC user, pero I believe i can make an educated guess:
- Enable the hardware interrupt of the timer driven by the 32kHz source.
- Put the MCU in SLEEP Mode or equivalent low power standby mode while it is powered from backup batteries.
- The MCU is awaken for a brief moment everytime an RTC interrupt occurs. This is the period where your RTC interrupt routine does its timekeeping job.
- And then, the MCU is put into sleep mode again.
The average power consumed by the MCU will be very low, allowing it to run on backup batteries for months or even years.

it would be my first time to implement this two xtal in one mcu interrupt. thanks!  ;D

hmmmm.... mapag-experimentuhan kaya... tamang tama at my 16LF628A pa ako dito.

papano mag-iimplement ng backup power?
