Static RAM?

Eli

Hello,


I was wondering if the propeller chip has any free EEPROM or static RAM space available. I want to be able to save a user-given value so that it is not erased when the processor is reset. Any ideas or suggestions regarding this would be greatly appreciated. Thanks.

Somebody from Parallax posted a cool object that saves your variables back into the EEPROM from whence it came. Doing it this way, you don't need any extra EEPROM and it's very easy to use... I used it in my Delay Generator Demo here:

I think it's part of the PE Education kit, if you want to search for that...

Use the Eprom object from the object exchange
See example code from a small f\project that had to save and reload preset timers values

CON MaxTimes = 6 'Allow for 6 timer presets
VAR Long Time[noparse][[/noparse]MaxTimes] 'Timers preset value
OBJ
Eeprom : "Eeprom"


PRI SaveVars '' Save timers to eeprom
Eeprom.VarBackup(@Time,@Time+4*MaxTimes-1)
ser.str(string( CR, LF, " Timers saved.. ", CR, LF))

PRI LoadVars | n '' Load timers from eeprom
eeprom.VarRestore(@Time,@Time+4*MaxTimes-1)

Eli, the protoboard has an eeprom that is twice as big as the PEKit's. The upper half is strictly under programmer's control. Data placed there can only be changed by your own program.
