Timing in PICBasic Pro commands

[freelancebee]

Hi Bruce:
Thank you for your time.
The code you wrote will really help.
Thank you again.
For some kind of tasks need 36 hours to complete production cycle.
During this working time cycle PIC has to work by changing output codes
depends from pre-programmed time intervals for example 90 minutes and
preprogrammed speed, temperature, or current=load and real conditions
on sensors.
Time=0
Start speed1, temperature1, or current=load1......
Time 90 min
Speed2, Temperature2, Current load 2......
Time 180
Speed3, Temperature3, Current load3.......
....
Time 2160 min = 36 hours
Stop
What is your suggestion or what kind solution for 36 hour cycle is real
and cheapest one:
- use external pre-programmed IC Timer on interrupt
- Use external EEPROM as counter and flag on interrupt
- use sources of PIC - EEPROM counter and flag on interrupt
Thank you again.
Best Regards,
Leonid

Tons of different way i guess but one of my favourite is an external RTC like DS1307. You can even use an internal timer to do it too. OR depending what else your PIC do, do everything in a loop with a mix of PAUSE and incrementing few variables like secondes/minutes/hours/day/week/month/year

and that thread should give you an easy to implement solution
