18F1320 ... Strange Memory

[Acetronics2]

Hi, Mel and Luciano

PbP is 2.46 "patched" release, and MPASM v 5.02 ... and ... no chance to use PM here !!! ( 18F1320 not supported ... it says)

If you want, I send you the code ... no secrets there !!!

There are no interrupts in this program ... I ever try not to use ... to avoid input parasitic signals difficulties ...

I've read memory w/ my picstart ... that's how I found what was happening.

The only thing I didn't try was to write into the memory not only 8 but, say, 20 values following each others...

I changed the values types ... no more luck !!!

And do not forget memory use is OK with 16F devices ...

Thanks for your Help

Last news :

I added a value at position 9 (0 ) and copied the "writes" from location 1 to 9 to 21 to 29 ...

result : all values Written ... except value at loc.2 that has been overwritten by "FF" .... my three lonesome further values always aren't written.

may be there are overwritten too ... i'll never know.

one sure thing ... there's a writing problem !!!

Hi, SOUGATA

All writing protections have been removed ... I have to program in two times : at first config , and then program. default configs locks the programming !!!

WRITE 2,NeutreC.lowbyte
WRITE 1,NeutreC.highbyte
WRITE 4,GaucheC.lowbyte
WRITE 3,GaucheC.highbyte
WRITE 6,DroiteC.lowbyte
WRITE 5,DroiteC.highbyte
WRITE 7,Invert   <<<<<<<<< Invert is declared as BIT
WRITE 8,Side   <<<<<<<<< Side is declared as BIT

I don't use PicBasic.

Will "WRITE" support the BIT data type?
Try to declare the variables Invert and Side as BYTE.

Best regards,

Hi, Luciano

Bit is well written in the EEPROM ...

I notice some problem with the programmer software too
in writing the EEPROM data for the memory location.
But seems melabs has corrected on their newer ver 3.31.
I can tell from running debugging while reading the EEPROM
data via rs232.

Hi,

I've tried to see closer what's happening, so :

Values are Written 3 times, at locations 1-12 , then 21-32, then 41-52 ...

Memory is filled w/ zeros at programming time

Then run ...

Attached is the EEPROM Dump ...

Locations $0A, $0B and $0C are a bit surprising ... Values should have been $7F ... as loc. $1E, $1F, $20 and $32, $33, $ 34.

a bug somewhere ???

Alain,

Can you try declare the variables Invert and Side as BYTE?
(Just a quick test).

Best regards,
