HSEROUT to LCD with 16F887

[menta]

I'm trying to use my LCD (PIB-216) with the USART.
According to the data sheet the TX output is RC6.
I tried this code but I only see garbage. Maybe the codes I send ae wrong.
Please advice.

DEFINE HSER_TXSTA 24h
DEFINE HSER_SPBRG 25 ' 9600 Bauds

PAUSE 2000
HIGH PORTD.7
HSEROUT [254,128,65,65]
END

Hi Menta,
is the serial LCD set to receive true?

What do you mean ?

If I connect the LCD on portB.1 and send
SEROUT PORTB.1,6,[254,131,#HH,58]
It display correctly.

I connected PORTC.6 to RB7 (the PICkit 2 UART tool serial input)
and I see ???????? when the HSEROUT command is printing.

ok, I have managed to see the correct data that was send by HSEROUT in the PICkit2 UART tool when setting 2400 baud. I also changed the LCD mode to 2400, but it still show junk.

DEFINE HSER_TXSTA 10100000b
DEFINE HSER_BAUD 2400
DEFINE HSER_SPBRG 25 ' 2400 Bauds

PAUSE 2000
HIGH PORTD.7
main:
HSEROUT [65,13,10]
PAUSE 2000
goto main

You can send data through a serial link either TRUE or INVERTED. I am sure using HSEROUT the data is always true, whereas your serial LCD may be either true or inverted, if your serial LCD is set to accept data in inverted form, then you will see characters looking like gibberish.

You say this works:SEROUT PORTB.1,6,[254,131,#HH,58]<br>
the 6 is telling me N9600 baud, which is inverted so you must reset in software the serial backpack to accept TRUE in order to read properly.
