Hi everyone!

I'm having some trouble intializing the ds1307 rtc. I've included the codes I'm using for initialization and demo . Please take a look at them and point me if i have the things in the right place or not.

Thanks in advance

    sorry about that...i using different sources now, which i'm not able attach to the code here... but it can be found on obex.parallax.com
    The programs I'm using now are:
    DSRTC_driver
    FullDuplexSerial
    Extended_FDSerial <-- Extended Full Duplex Serial on obex.parallax
    LCD RTC demo

    I'm getting error in LCD RTC demo program. I've bolded and underlined as to where it's indicating the error. The error is "Expected a Subroutine Name"
    PUB Main
    LCD.init(TX_PIN, BAUD, 2, 16)
    LCD.cls
    Can anybody help me out on how to fix this error!!

    Thanks

    If you are using my 12/24hr code, I used a Sparkfun serial LCD display.

    If you just want to display the time on your PC using the Parallax Serial Terminal, just remove the LCD code.

    Make sure you have specified the correct pins for the RTC clock and data pins.

    oh ok...i fixed it as per ur code....now all programs are loaded...what is the next step?? should the time automatically appear on the LCD??

    in the serial terminal its giving me some other characters updating every second not the rtc clock.

    No, if you're running the code that was attached above, you need to run the Parallax Serial Terminal at 57600 baud rate.

    You have to activate the Parallax Serial Terminal quickly after loading the program.

    If the clock has not been set, enter "y" at the "Enter 'y' if you want to set clock:" prompt and enter the year, month, day, etc to set the clock...

    I'm not getting the prompt to set the date and time.

    Make sure you start the Parallax Serial Terminal, set the appropriate Comm Port and set Baud Rate to 57600.
    Load the program from the Propeller tool (F11) and immediately click the enable button on the Serial Terminal.

    The program gives youe 3 seconds to respond.

    If you miss it, hit the reset button on the Propeller board...

    If you are not familiar with the Parallax Serial Terminal, you should read up on it

    Ok thanks a lot. I have the clock running on the serial terminal. I've to work further to make it display the time and date on the LCD.

    how can i make this time and date display on the lcd??? I've included the code,but I've excluded all LCD lines because I'm getting "subroutine error" on the following line:
    PUB Main
    LCD.init(TX_PIN, BAUD, 2, 16)

    Could u please check the code and guide me how to fix it....thanks

    What LCD device are you using and what OBEX diver?

    Your particular LCD and OBEX code probably have totally different routines and parameters that the Sparkfun LCD/driver I used.

    You are going to have to do a little work here. This appears to be a parallell LCD (using 8 or four pins).

    You need to find an OBEX object (or other code) that will work with your LCD and study the code to learn how to use it.


    NOTE: you got it working before my post :smile:

    The LCD I'm using is not a familiar one like HD4480, so can i still find a OBEX object for this lcd... and yes I'm using 4 bits

    The LCD is working fine with the previous LCD driver and demo code...and time and date is displayed on the serial terminal, but not on lcd because I've commented the LCD parts in the LCD RTC Demo.spin. If I don't comment it then I get subroutine error on this line
    PUB Main
    LCD.init(TX_PIN, BAUD, 2, 16) <-- "subroutine" error

    so I want to know what 2 and 16 are in the code??

    I wrote my OBEX object to work with specific Sparkfun serial LCDs. Some have 2 lines some have 4 - some have 16 characters/per line and others have 20.

    The 2, 16 indicate rows and columns. Many OBEX objects work with very specific devices - they are not universal drivers.

    My LCD code won't work with your LCD.

    would ur sparkfun serial LCD driver and demo code work if I used JHD162A 16x2 LCD with a driver HD44780??
  • Ron CzapalaRon Czapala Posts: 2,418

    Nope - serial LCDs only use 2 wires (ground and signal) and Sparkfun has their own specific command codes which are different from the Parallax codes, etc ,etc

    I'm not sure I understand. You're able to get the LCD to work in demo routines, and you're able to get the clock to work on a serial terminal? You just can't get the clock and the LCD to work together?

    Here's something hacked together from my I2C and LCD routines, with some glue code to allow for setting the time.

    yes, this is problem I'm having....so if I use the code you've given me will I be able to see the clock running on the LCD instead of serial terminal??

    In your LCD driver.spin code you have given:

    PUB start(E_pin, RW_pin, RS_pin, D4_pin) : okay
    stop
    pins[0] := E_pin
    pins[1] := RW_pin
    pins[2] := RS_pin
    pins[3] := D4_pin

    the 0,1,2,3... is the propeller pins numbers which your using to connect E, RW, RS, and DB4??
