Using Propeller RTC emulator

Lev

I am trying to return current hours, minutes, and seconds from the Propeller_RTC_Emulator to my spin program as separate values. I believe the varaibles are HH, MM, and SS in the RTC emulator. I have been unable to get any value for these variable, other than a zero. Does anyone know how to return these separate values from the RTC emulator? Here is the relevant section of code calling the RTC.

'Main Loop
repeat

Clock.ParseDateStamp(@DateStamp) 'get date and time stamps from RTC emulator
Clock.ParseTimeStamp(@TimeStamp)
' **** need something here?????
mission_time := HH*3600 + MM*60 +SS 'calculate mission time in seconds from RTC emulator

LocLong := (LocLongDeg*60) + LocLongMin 'calculate minutes of longitude
LocLat := (LocLatDeg*60) +LocLatMin 'calculate minutes of latitude

The DateSTamp and TimeStamp are in ASCII. you must convert the ASCII string to a number


This is a bit of a hack. The TryParseTime method takes a pointer to the @TimeStamp and the time part you want to convert to an integer.

0 = Hour
1 = Minute
2 = Second

PUB TryParseTime(time, idx) | value, ptr

  'Move the string pointer to hours, minutes, or seconds
  ptr := time+idx*3

  'convert to an integer and multiply by 10
  value := (byte[ptr++] - $30) * 10

  'Conver to an integer and and add to the last calculation
  value += byte[ptr] - $30

  return value

At some point you started the emulator passing it an address. Just grab the values from there, e.g.

RTCemu.start(@time)
  
  temp := time
  HH   := (temp >> 12) & $0F
  MM   := (temp >>  6) & $3F
  SS   := temp & $3F

or

RTCemu.start(@time)
  
  vscl := time                  ' unused SPR
  HH   := vscl[15..12]
  MM   := vscl[11..6]
  SS   := vscl[5..0]

I just came across the UnParseTime(TimeAddress) method in Propeller_RTC_Emulator.

Thank you a bunch Mike and kuroneko! Your suggestions work well.
