For Mike Green:

After four days of effort, I finally got the Proto Board communicating with my 4x20 LCD.· The problem was with the line:

serialOut(6,c,stampBaud,sim#NInv,8)

I changed it from non-inverted to inverted and Bingo! - it worked.

Now I have another little problem.· I was to display the date/tine from a DS1302 in HEX2 format.· With the Stamp I write:

serout...HEX2 month, HEX2 date..etc.

and for the Prop I write:

text.hex(month,2) and so on.

The problem is, there is no way, using the simulation object, that I can send something like #07 as a byte.· Would you have time to write a
"sendhex'" method for simulation that would let me send the DS1302 parameters to the LCD in HEX2 format, so I could write something like:

sendhex(month,2)
·· hexOut(6,...(something).......stampBaud,sim#Inv,8)

If you don't have the time, that's OK.· I can mathematically manipulate the 1302 data so it goes to the LCD in the right format - it just takes a lot of time and uses quite a bit of memory.

Thanks

Sid

Sid,
I'm not sure where I saved a copy of the "simulation object". Please post a copy or a link to where I sent it to you and I'll have a look at it ... probably Thursday.

Mike, here is a copy of the simulation object. Thanks a bunch.

Here's one routine for outputting variable width decimal (like DEC) and one for fixed width hex (like HEXn). These are just copied from the Propeller OS display routines and slightly modified to work with the serialOut routine here. I've not tried to compile them, but they look ok. Note that, just like the character output routine (which these use), they sandwich the "real" information (like the value to use) between the pin # and the Baud/mode/bits to be used. The "digits" parameter in the serialHex routine is the "n" in "HEXn" (the number of hex digits to output). Just stick these at the end of Simulation.spin.

PUB serialDec(pin, value, Baud, mode, bits) | i       ' Transmit a decimal number
  if value < 0
    -value                                            ' Put out leading minus if negative
    serialOut(pin,"-",Baud,mode,bits)
  i := 1_000_000_000                                  ' Handle up to 10 significant digits
  repeat 10
    if value => i                                     ' Skip leading zeros
      serialOut(pin,value / i + "0",Baud,mode,bits)
      value //= i
      result~~                                        ' Indicate first significant digit
    elseif result or i == 1
      serialOut(pin,"0",Baud,mode,bits)               ' Always output at least one digit
    i /= 10

PUB serialHex(pin, value, digits, Baud, mode, bits)   ' Transmit a hexadecimal number
  value <<= (8 - digits) << 2                         ' Position the value based on # digits
  repeat digits                                       ' Rotate and translate to hex chars
    serialOut(pin,lookupz((value<-=4)&$F:"0".."9","A".."F"),Baud,mode,bits)

Mike, that works great - just what I wanted.· You save me 140 longs of memory.
