I SEND THE CARACTER TO PIC AT PC WITH 9600/8/E/1
i HAVE CONFIG DEFINE HSER_EVEN 1, BUT THE COMUNICATE IS 9600/7/E/1. WHAT IS THE DEFINE?

[Melanie]

1. For 7E1 add the define...

DEFINE HSER_EVEN 1

2. For 7O1 add the define...

DEFINE HSER_ODD 1

3. For 8N1...

Do NOT add any defines


The following additions below are only valid for PBP 2.44 or later...

4. For 8E1...

Define HSER_EVEN 1
Define HSER_BITS 9

5. for 8O1

Define HSER_ODD 1
Define HSER_BITS 9

Note that options 4 & 5 are ONLY available from PBP version 2.44 onwards which added the HSER_BITS 9 define. If you have an older compiler, it's time to get in contact with MeLabs for an upgrade.

I have 2.44 but HSER_BITS 9 NOT COMPILE THIS DEFINE

[MICOCALI]

DEFINE OSC 20
DEFINE HSER_RCSTA 90h
DEFINE HSER_TXSTA 24h
DEFINE HSER_BAUD 9600
DEFINE HSER_CLROERR 1
DEFINE HSER_EVEN 1
DEFINE HSER_BITS 9


I HAVE THIS DEFINE BUT THE COMUNICATE IS 8N1
WHY

[Melanie]

Define HSER_BITS 9

Compiles without error with my version of 2.44

[MICOCALI]

IF POSSIBLE COMPILE THIS FILE FOR ME
THANK

[MICOCALI]

THE PIC IS 16F628

[Melanie]

I've compiled it twice for you... (two posts since I can only add one attachment at a time)...

This is done with PBP version 2.44

It is actually a .HEX file, but again this forum doesn't allow .HEX attachments so I renamed it as a .TXT

[Melanie]

And this is compiled with PBP version 2.45

@ Melanie

you are right, the example compiles ok

but what MICOCALI is saying is also correct.

I have just tried it with:
-----------------------------
DEFINE LOADER_USED 1
DEFINE OSC 20

DEFINE HSER_RCSTA 90h
DEFINE HSER_TXSTA 24h
DEFINE HSER_BAUD 9600
DEFINE HSER_CLROERR 1
DEFINE HSER_EVEN 1
DEFINE HSER_BITS 9

Loop:

Hserout ["Test: 0 1 2 3 4 5 6 7 8 9"]
Pause 1000
goto loop

END
-----------------------------

The PIC communitates with 9600 8N1

[MICOCALI]

thank you NavMicroSystems
but I make connection with pic at 9600/8/E/1
i HAVE USE THE FILE PANA245 BUT COMUNICATION IS 8N1
NOT 8E1 I HAVE TESTED WITH HYPERTERMINAL

[Melanie]

Have you checked that you get the same erroneous result with PBP244 and PBP245?

[MICOCALI]

I HAVE TESTED PANA 244 AND PANA 245 BUT THE COMUNICATION IS 8N1 WHY ALL THIS?

[Melanie]

It looks like HSER_BITS 9 was added when the HSEROUT2 and HSERIN2 commands (along with the HSER2_BITS define) were added.

I'll pull a PIC out with 2 USARTS and test both HSEROUT and HSEROUT2 later when I've some free time.

You can of course BYPASS the HSEROUT defines and set-up the PIC's registers manually...

[MICOCALI]

You can of course BYPASS the HSEROUT defines and set-up the PIC's registers manually

IN WICH MODE ?

[Melanie]

Just as a test... before we dive into playing with the registers... you're currently setting HSER_TXSTA to 24h. Since bit 6 of the TXSTA Register selects 8 or 9 bit mode, shouldn't you really be setting TXSTA to 64h??

Therefore try these defines...

DEFINE OSC 20
DEFINE HSER_RCSTA 90h
DEFINE HSER_TXSTA 64h
DEFINE HSER_BAUD 9600
DEFINE HSER_CLROERR 1
DEFINE HSER_EVEN 1
DEFINE HSER_BITS 9

[MICOCALI]

YOU ARE THE BEST THANK YOU FOR ALL

[Melanie]

Another happy customer... *smiles*

[NavMicroSystems]

Melanie,

you are so right!

In most cases a look at the datasheet really helps!

As I have a Board in front of me I have tested it, and with

DEFINE HSER_TXSTA 64h

and the PIC communicates @ 9600 8E1
