EEPROM write program

Mag748

Hello,

I am writing an application to write data from a DAT section to the upper part of the propeller EEPROM. I am having difficulty getting succesfull results. The program seems like it should be straight forward enough, but I must be missing something.

If anyone has time to loot at my code that would be appreciated. This is the output that I am getting when I should be getting a long string of text before the "End of String" statement:

Debug terminal is running on cog 2.
I2C Driver runs in Spin so no cog required.
Attempting to write a string...
Writing "testData" at address $8000.
temp = 128.
Wrote page at $8000.
temp = 128.
Wrote page at $8080.
temp = 18.
Enter address (HEX) to read string from:
Reading memory at address $8000:
0
--END OF STRING --

DONE Reading at address $8001.
Enter address (HEX) to read string from:
Reading memory at address $8001:

--END OF STRING --

DONE Reading at address $8001.
Enter address (HEX) to read string from:
Reading memory at address $7FFF:

--END OF STRING --

DONE Reading at address $7FFF.
Enter address (HEX) to read string from:

Get rid of the "@" before the Stringpointer in the bytemove. Stringpointer already contains the address you need. @Stringpointer is just the address of your pointer variable.

You have solved my problem. I thank you very much.

After I finish writing this program, do you think this would be a useful object to add to the object exchange? There doesn't appear to be any simple object like this already.

Thanks,

Hi Marcus,

Did you edit the content of your original post after your question was resolved ?

Hi Ford,

Yes, I removed the attachment that contained the non-functioning program. I plan to reattach the working code once it is finalized.

Thanks,
Marcus
