Hi!
To make a long story short, I am attempting to define a variable or constant which will be populated with the _eeprom value from the SystemTypes module which I can then use as a limiter for a mildly open-ended eeprom reading routine.

Thus far, I've discovered a few ways in which this does not work:

Code: Select all

{example of not working stuff}
'1
Const x = _eeprom 'nope

'2
#define Y = _eeprom
const x = Y 'nope

'3
dim b as byte
b = _eeprom 'nope

'4
#define Y = _eeprom 'works
dim b as byte
b = Y 'nope

I am running out of ways which I might use to accomplish this. Any help appreciated. Thanx in advance.

Try the online help file under 'EEPROM data'

eeprom [(address)] = (item [as type] {, item [as type]})

Negative, reading from the EEPROM works fine.

I am looking to read the PIC's maximum EEPROM capacity en silico, as it were.

I've done it like this before... probably other ways as well.

Code: Select all

#option _eeprom_size = _eeprom
const EEPROM_SIZE as word = _eeprom_size

It works!

Thanks.
