Does anyone out there have a program for the DS1302 on the Prop - I could really use one.·

Thanks

    Jason, that file is a partial program covering only hours, minutes and seconds.· Besides, its for TV, not VGA.

    Hello Newzed,

    The DS1302 programs published in the object exchange is a driver and a little demo program.

    I can help you to adapt it to what you need ?

    Could you explain exactly what you need ?

    Best regards,
    dro.

    Thanks for the offer, dro.· I have written a program using Mike Green's OS and it looks OK on the VGA.· Won't be able to really try it until I get my Proto Board and get my DS1302 hooked up to it.

    Right now I'm trying to convert the program to Chip Gracey's
    VGA_1280x1024_Tile_Driver_With_Cursor and I can't get the numbers to display.· I'm wondering if Chip's program has a provision to displaying decimal numbers.· As of now, if I enter a number it displays the ASCII value for the HEX of whatever number I enter.· For instance, if I enter '55', the VGA displays '7'.· Has me completely bugged.

    I'm using the 1280x1024 driver. The print routines used in the demo expects you to use ascii. When I need to format a number·to display,·I've used the Simple_Numbers object which will take·a number value and return a pointer to a formatted string that can be used by the print_string() method.

    Hello Newzed,

    I can not help you for the use of VGA object because i have no vga monitor. For the demo program, you can simply change the line :
    text : "TV_Text"
    by
    text : "VGA_Text"
    and it will work with 'standard' vga output.

    I can help you for the use of the DS13202 to obtaining the date and time as you need !

    Best regards,
    dro.

    Since apparently no one had a program for the DS1302, and I could not find a suitable one, I wrote my own.· I am not a proficient SPIN programmer, so this was really a labor-intensive effort.· I can't run the program myself until I get my Proto Board, but I have been assured by a forum member who did run it that it works as anticipated.· On that basis,m I am attaching the program, plus the six objects it uses.· Rather than zip them into a bundle, I attached them separately so you can download only what you need.· Please check the VGApingroup and the clock pins in the CON block to make sure they agree with your setup.

    I could only attach five of the seven files - the remaining two will be by separate post.

    Hello Newzed,

    Your program look to be great. I am particularly interested by your approach of the “object” concept as used with Propeller.
    I am impatient to be able to test the program when I would have a VGA screen.

    dro.

    Finally got my Proto Board all built up and plugged in the special DS1302 module I made just for this project.· Works great!· I have attached a picture of the Proto Board with the DS1302 installed.

    I finally got my DS1302/LCD program all finished and working. It will display either on your VGA or 4x20 LCD or both. The attached zip file contains all seven objects required by the program.

    A few notes – check the CON block to make sure the VGA start pins and the 1302 connections agree with your setup. The 1302 uses HEX2 notation throughout – if the month is July, enter as 07. If the time is 9AM, enter as 09, and so on. DO NOT PRESS ENTER. The program will advance automatically after each entry.

    Make sure you use 3.3VDC on the 1302.

    I am using my 4x20 backpack for the LCD, so you will have to change the LCD routines beginning at Line 381 to fit the LCD you are using.

    Note that Lines 134-137 have been commented out. This permits using the Prop/LCD remotely, which is what I am presently doing.

    The 1302 routines do not use the synchronous shiftin/shiftout protocol. Instead, they write/to or read/from the particular clock registers asynchronously.

    If you are using the D or L options in the VGA/keyboard mode, these options can be terminated by pressing any key. If you are using the LCD as a stand-alone remote, the only way to terminate is to power off the Prop or Proto Board.

    If you have any questions about the program, please post them here.

    Hi,

    Will the DS1302 work with a crystal taken from a watch?

    Thanks,
    Doug

    No.· The correct crystal is a Digikey 300-8301 for about $0.28, 32.768Khz, 6pf.

    What is the pf that is needed for the propeller?
  • NewzedNewzed Posts: 2,503
    edited 2007-08-05 23:35
    hinv, if you are talking about the 1302, the pf is 6.· If you are talking about the crystal for the Propeller, that is 20pf.

    Is the schematic for your little board published? Perhaps something I can add to the Cookbook?
