Serin Serout Help

[Darrel Taylor]

Your flowpin is on GPIO.3.

SERIN2 GPIO.1\GPIO.3, 3313, [DEC X]

Put the serial data on GPIO.3, and the flowpin on GPIO.1.
flowpin needs to be able to output.

And set GPIO.0 to OUTPUT for the LED.

OUTPUT GPIO.0

Don't forget to disable MCLR in the configuration.

I have been working on the code for a couple of days. I have made a small progression if i manually send a "1" to the SERIN it will assume a flash rate of 1. this is done by placing the datapin wire to ground. Hear is the current code i am working with. Any help would be great, Thanks!

Recive:
Clear 
define ocs 4
INCLUDE "modedefs.bas"
@_config_HS_osc &_WDT_OFF &_LVP_OFF &_CP_OFF &_BODEN_OFF
ADCON1 = %00000111
CMCON = %00000111
TRISA = %11111111
TRISD = %00000000
X VAR BYTE
SERIN2 PORTA.5\PORTA.1, 3313, [DEC X]
LOOP1:     
   HIGH PORTD.2
   PAUSE X
   LOW PORTD.2
   PAUSE X
GOTO LOOP1
END  

Send:
Clear 
define ocs 4
INCLUDE "modedefs.bas"
@_config_HS_osc &_WDT_OFF &_LVP_OFF &_CP_OFF &_BODEN_OFF
ADCON1 = %00000111
CMCON = %00000111
TRISA = %00000000
TRISD = %00000000
PORTA = %00000000
LED VAR PORTA.1
X VAR BYTE
X = 100
LOOP1: 
   SEROUT2 PORTA.5/PORTA.1, 3313, [100]
   PAUSE 5000
GOTO LOOP1
END

Thanks again!

Hi MangoKid,
I am away from MY Computer and my books, but if I understand this last statement correctly,
" this is done by placing the datapin wire to ground."
I believe you are referring to the ports "Idle State" if so here is the little secret: If you are sending TRUE the port wants a pull up resistor and if you are sending INVERTED the port wants a pull Down resistor.

Not sure what you mean by datapin...
But..
On the receive side you are only checking the serial port once,

SERIN2 PORTA.5\PORTA.1, 3313, [DEC X]
LOOP1:     
   HIGH PORTD.2
   PAUSE X
   LOW PORTD.2
   PAUSE X
GOTO LOOP1

Put the SERIN2 line inside of LOOP1.

Thats prolly my fault. Way back at the beginning I suggested to take it out of the loop. I was thinking it would be gotten before entering the loop.

Thanks again i moved SERIN inside the loop but to no avail. I am assuming there is an issue with my baud rate. If i am sending should the sending and receiving baud rate be identical or should one be inverted?

Thanks for the help

So after alot of headaches i have finally got SERIN SEROUT working . The first and biggest problem was the baud rate i was using the initial (3313) is only meant to communicate with a level converter. I am using (27889) which is 7bit with even parity. Here is the code i hope it helps anyone else who is stuck with the SERIN SEROUT.

Send:

clear
DEFINE OCS 4
ADCON1 = %00000111
CMCON = %00000111
TRISA = %11111111
TRISD = %00000000
X VAR BYTE
X = 555

LOOP1:
SEROUT2 PORTA.5, 27889 , [244]
PAUSE 500
GOTO LOOP1
END

Recive:

Clear
define ocs 4
ADCON1 = %00000111
CMCON = %00000111
TRISA = %11111111
TRISD = %00000000
X VAR BYTE

LOOP1:
LOW PORTD.3
SERIN2 PORTA.5, 27889, [X]
HIGH PORTD.3
HIGH PORTD.2
PAUSE (X * 10)
LOW PORTD.2
PAUSE (X * 10)

GOTO LOOP1

END

Thanks Again to all those who helped solve this.
