More Variables

Mohamed Refky

Hello,
In my weigh scale application I already using keypad to inter numbers as setpoint 1 and setpoint 2.
Another application there are 8 ranges of weight for example: 400 to 420,421 to 440,....... and the user need to program the 8 ranges ( changeable ) and that means· many variables.Any idea would be appreciated.

((The application is used· for packing grape punnet and lamp is on for each range in a table with 8 channels))

Thank You

If the values don't change often, you can store them in the EEPROM used to store the program. Look at the description of the READ/WRITE commands in the manual. Keep in mind that EEPROMs have a limited number of times that any one location can be written (at least 100,000 times). Usually programs are designed to check the current value of a location and only do a WRITE if it is different from the value to be written like:

  read location,temp
  if temp = newValue then skipIt
  write location,newValue
skipIt:

Alternatively, some Stamp models have RAM memory that can be accessed with the GET/PUT statements. These have no constraints on the number of times they can be written, but the values go away when the power goes off. Again, look in the manual for descriptions and examples.
