Bean...below is some code that I use to send stuff to the "terminal" aka computer screen in the IDE , and not to my LCD. (two different BAUD rates)
SEROUT 30, baud2, 13
    SEROUT 30, baud2, 10
    SEROUT 30, baud2, "TEMP_100 = "
    valueSTR_1 = STR TEMP_100,3,5
    SEROUT 30, baud2, valueSTR_1

The "10" is a NEWLINE and the "13" is a CARRIAGE RETURN. What is the/a control character for "HOME" aka 0,0? Is there a list of control characters, more then you list in 00.01.43?

Thank you...Denno

  • If you're using PST, these are the control codes that it understands (this is Spin source).
    con { pst formatting }
    
      HOME     =  1
      CRSR_XY  =  2
      CRSR_LF  =  3
      CRSR_RT  =  4
      CRSR_UP  =  5
      CRSR_DN  =  6
      BELL     =  7
      BKSP     =  8
      TAB      =  9
      LF       = 10
      CLR_EOL  = 11
      CLR_DN   = 12
      CR       = 13
      CRSR_X   = 14
      CRSR_Y   = 15

    Thank you Jon...much appreciated...
  • And, another little question for Bean, reference PROPBASIC

    The following code is for the basic stamp
    SHIFTOUT DIO_n, Clk, LSBFIRST, [%0\1,RTCCmd\5,%10\2,Temp]
    

    Question...how do I do that in PROPBASIC?

    I keep getting the error message in PROPBASIC.."To many parameters"...aka...Error 7

    Thank you...
  • You can't do that in PropBASIC -- as the compiler is telling you, there are too many parameters. If you have less than 32 total bits, you could assemble your output into a single long, then shift that out. In your case it looks like 16 total bits.

    OK...thank you again Jon...

    The compiler seems to like this:
    SUB WriteRTC                        'Write to DS1202 RTC
      CS_1302 = on_
      SHIFTOUT data_IO, Clock, LSBFIRST, %0\1''''''''''''''''''''''',RTCCmd\5,%10\2,Temp
      SHIFTOUT data_IO, Clock, LSBFIRST, RTCCmd\5
      SHIFTOUT data_IO, Clock, LSBFIRST, %10\2
      SHIFTOUT data_IO, Clock, LSBFIRST, Temp
    ''SHIFTOUT datapin, clockpin, mode, value[\bits][,speed]
    ''If the bits parameter is not specified, 8 bits are sent.
    ''mode: LSBFIRST, MSBFIRST
      CS_1302 = off
    ENDSUB
    

    I'll see if it runs when I finish the whole program...
  • Actually, in the above I see the error of my ways...LOL...but, in the SHIFTOUT in PROPBasic, what is the "speed"?
    Thank you...
  • You really should track down the latest copy of the docs. I've attached what I have, but it may not be the latest.
  • I haven't seen it in any docs but @pmrobert had a look at the compiler source:


    https://forums.parallax.com/discussion/164268/propbasic-i2c-what-is-the-default-speed#latest
  • I do have the latest docs on propbasic...1.48...again thank you...
  • Has anyone had any success running the DS1302 time chip using PROPBASIC?

    Thank you...
  • Hi
    Yes
    What do you want to know?

    Not sure if you followed the link regarding the I²C default speed? It wasn't about documentation.
  • Dave..how did you do it, I'm having issues with the SHIFTOUT and SHIFTIN commands. I have used the ds1302 many times over the years with the basic stamp and was trying to follow those guidelines with propbasic.

    Would you mind sharing you code?
    Thank you..

    Hi
    Will have to dig it out but there is nothing clever just straight forward shiftout and shiftin

    for shifting out I use-
    SHIFTOUT DataIO, Clock, LSBFIRST, reg0 '(SHIFTOUT datapin,clockpin,mode,data)

    and for shifting in
    SHIFTIN DataIO, Clock, LSBPRE, ioByte '(SHIFTIN datapin,clockpin,mode,data)

    works for me.

    Show me your code and I can test it.

    Dave
  • well, Dave, my code is not that simple and that's probably my problem. However, there are three SHIFTOUT's with different "data's" just to initilize the DS1302. Then a SHIFTOUT with the "burst", to then get to the SHIFTIN which is the ioByte you mentioned.

    What are you defining as the "reg0"....? The following is the code I am trying to get things started....
    '
    SecReg                 CON        %00000 'register locations
    MinReg                 CON        %00001 '            "

    trickReg               CON        %01000 '            "

  • Hi
    My suspicion is that you are trying to use pbasic syntax for propbasic the two are NOT the same.

    This is a test program that requires you use the serial port to both program and communicate with the prop.
    Set up a terminal program -I use Tera term -
    Disable it so you can program the prop
    Then re-enable and watch the output.
    Study the code and compare the syntax used and use and adapt the bits you need.

    Its not exactly the most elegant code but it should give you a start.

    Tritonium...aka...Dave. Thank you for your code in PROPBASIC and the DS1302. I am still having issues getting it to run. I have done as you suggested in using the PST to view the output, switching back and forth for programming the prop and viewing in the PST. I have tried many, many things to get a "time" output without success. Below is the only output I get on the PST.

    "Mon/ 1/Jan 20 0 0: 0:80 0 0 2 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 2 0 0 0 0

    Any thoughts..
    And thank you for your help/time.

    Hi

    Well its a puzzle.
    It looks as though you are reading in mostly zero's so I wonder if the pins are mixed up- remember the first pin on the prop is I/O pin 0 not pin 1 (ie prop pin 1 is I/O pin 0) so pins...
    CS1302	PIN  13 low '0 low			'sel      -	chip select active high  DS1302 pin 5
    DataIO	PIN  15 input '1 input    	'I/O      - Performs R/W to DS1302 pin 6; 2k2 resistor i/face
    Clock	PIN  14 low  '2 low  		'clk      - Connects to DS1302 pin 7
    

    pin 13 refers to I/O pin 13 NOT physical pin 13. and so on so
    CS1302	PIN  13 low    'is physical pin 14
    DataIO	PIN  15 input 'is physical pin 16
    Clock	PIN  14 low    'is physical pin 15
    
    on my clock board the CS pin is labelled RST !!!!!

    Mine is running off 3.3v with 2.2k resistor on the DAT line, left on after starting with 5v then finding 3.3v worked.

    Dave



  • Thanks again Dave...I'll keep playing around with it. I am using the same "clock board" that you are using, I believe, as mine says "RST" also. Plus, all my pins are numbered on the Propeller "FLIP" which is what I am using.

    I have tried running on 5 volt and 3.3 volt. No difference. The only thing I have not done, is use a 2.2K resistor on the data line to the prop. But, that was only for the 5 volt operation of the DS1302. Must be something on my end...even when I "uncomment" the section to set time and date, there is no change...

  • Hi

    Just took a look at the flip module- yep all the I/O pins are clearly labelled so that can't be it.
    I wonder if when you tried it using 5v that the data line pin got damaged when the clock output a 5v signal?
    Might be worth while connecting to 3.3v and try new pins.
    Otherwise I'm out of ideas.
    Actually the guy having trouble in the SPI thread found his I/O pin had blown- so worth a try.

    Dave
  • I got it...yah...first I took the time module, and put it on a board with the BS2sx, a program I wrote along time ago, and it worked with the stamp just fine. I reinstalled it on the other breadboard with the FLIP, same pins, and BINGO..off and running. I have been fooling, around with this for days now..as you know.

    Don't have a clue, what I did. But, thank you for your guidance and help. If you don't mind, I will use your program with another project..I'm building my own, programmable home heating thermostat. Yes, I know you can just buy one, but what is the fun in that...really. And I needed a time source. I have always paid attention to the temperature of different things...especially on my boat...etc..

    Again, thanks

    Hi

    It happens- after a while you start believing in ghosts!!
    Glad its sorted.
    Re-inventing the wheel is great fun.. because its your wheel. :)

    Tritonium...Dave...I have got my home thermostat working on the breadboard, but I was wondering if you could "comment" a little more on the following code...
    HIGH CS1302 
    	SHIFTOUT DataIO, Clock, LSBFIRST,RdBurst
        PAUSE 500
    	for adr=0 to 6	'convert from bcd to decimal
    		SHIFTIN DataIO, Clock, LSBPRE, tvar1  'here
    		tvar2=tvar1>>4                                 'here
    		tvar2=tvar2*10	'10's                   'here
    		tvar1=tvar1 and $0f                           'here
    		tvar2=tvar2 + tvar1                           'here
    		Wrbyte secs(adr),tvar2	'secs is first item in hub ram table. adr is index to others
    	next
    	low CS1302
    

    And here...
    'convert  binary to bcd in clock data table. 
      SUB BCD_Convert
        FOR index = 0 TO 6
          rdbyte secs(index),value
         ' example 				 value=23
          char=value/10		       'char=23/10=2
          char=char<<4			'mov 2 to msnibble char   "Especially here..."
          stmp1=value/10		'stmp1=2
          stmp1=stmp1*10		'stmp1=20
          stmp1=value-stmp1	'stmp1=23-20=3
          char=char or stmp1	'or into lsnibble char making BCD version    "and here"
          wrbyte secs(index),char
        NEXT
    

    The thermostat has two functions...One is controlled by the time, if selected, left push buttons control time, and the other function is setting by temperature, right push buttons. If the time function is selected, the heater will come on at selected hour, unless the temperature is already above the set temperature. If the temperature function is selected, then the heater will only come on if the temperature drops below the set temperature.

    I'm guessing I don't understand BCD to decimal...

    Anyways, I will be designing a PCB for ExpressPCB and use the PROPMINI instead of the FLIP...
    Thank you again for your time and knowledge.

    Hi

    Ok. BCD stands for Binary Coded Decimal. It's the way the time is stored in the clock chip. See the data sheet clip-
    The time is broken down into two decimal numbers-one representing tens and the other units, the tens is stored as the most significant nibble (4 bits) and the units as the least significant nibble (4 bits) and combined to make a byte. So 32 minutes would be-
    number 32 in BCD           3     2
    is stored as            0011  0010      ($32 in hex, 50 in decimal)
    number 32 in binary is  0010_0000
    
    (You can see that if you take the BCD and display in hexadecimal format you get what looks to be the right number- but that's just an artifact that only works for nibbles 0-9, hexadecimal goes up to F. If you find that confusing ignore it!)
    So since we deal in 8 bit binary units there is a need to be able to convert back and for.
    'read in the register to tvar1
    SHIFTIN DataIO, Clock, LSBPRE, tvar1
    
    taking the number 32 as an example 0011_0010
    
    'start with the tens part- shift tvar1 right 4 bits removing the units and leaving the tens part where we need it.   
    tvar2=tvar1>>4       'tvar2 now equals 0000_0011  (3)
    
    'now multiply the tens unit by 10 to give a binary result.
    tvar2=tvar2*10	'tvar2 now equals 0001_1110   (30)
    
    'tvar1 still holds the original clock value and now we need the units so we logical AND the tvar1 with $0F  (0000_1111) leaving just the units'
    tvar1=tvar1 and $0f       'tvar1 now equals 0000_0010  (2)
    
    now we have the tens converted and the units so all we have to do is add them together
    tvar2=tvar2 + tvar1    'add units and tens 0000_0010 + 0001_1110=0010_0000   (2+30=32)
    
    tvar2 contains the binary representation of the BCD value.
    

    Phew!

    I leave the other conversion as an exercise for the reader.... :)
