Greetings,
I am using a PIC16F628A and I am trying to send serial data using SEROUT2. My code basically is
--------------------------
cmcon =7
IF (PORTA.1 = 0) then pressed
goto main
pressed:
SEROUT2...(etc)
-------------------------
I am getting a compile error stating that SEROUT2 is invalid. I think it has something to do with "cmcon =7" because when I delete it it compiles correctly (I need the cmcon line because without it the button will not work). Any help is appreciated!

there's no chance it have something to do with CMCON. Check your SEROUT2 syntax or post your whole code here.
BTW, why are you using SEROUT2 when your PIC have a USART? HSEROUT on the right pins is far better.
Ooops! I caught my incredibly stupid error (I didn't define the serial modes). Sorry for wasting your time, mister_e. I do have a question though. What are the benefits of using the hardware serial ports over SEROUT2? Thanks for your time.

Have a look there => http://www.picbasic.co.uk/forum/showthread.php?t=4681
Everything is covered and well explain.
The ONLY limitation, is that you have to use the dedicated pins of the USART... i never felt it was a limitation so far :D
Ok, here is all my code. I will change the two lines concerning serout2 and serin2 with the hardware serial ports code. Basically this program just receives the button input, outputs the serial data (to itself; it is a test circut so don't bother asking why...) and supposedly receives the data and turns on the LED. It isn't working though. Thanks for the link to the HSEROUT/HSERIN page, by the way.
CODE:
-----------------------------
INCLUDE "modedefs.bas"
Pre CON $A5
Synch CON "~"
CMCON =7
main:
if (PORTB.1 = 0) then pressed
pressed:
serout2 PORTB.2, N2400, [Pre, Synch,"1"]
serin2 PORTB.3,N2400,[WAIT(Synch),in]
if (in == "1") then
high PORTB.4
pause 250
low OPRTB.4
pause 250
endif
-----------------------
Thank you very much for your help...

exclude the spelling errors from the code from my previous post...
Hi,
Try this one and read carefully the SERIN2, SEROUT2 section about the baudrate stuff. You will also foind a table in appendix A for the various baudrate values
Code:@ __CONFIG _INTRC_OSC_NOCLKOUT & _MCLRE_ON & _LVP_OFF & _WDT_OFF & _PWRTE_ON & _BODEN_ON
TRISB = %11101011
CMCON = 7
Baud con 16780 ' 2400 bauds
Pre CON $A5
Synch CON "~"
In var byte
LOW PORTB.2 ' inverted mode normal idle state
pause 50
Main:
if (PORTB.1 = 0) then pressed
goto main
Pressed:
serout2 PORTB.2, baud, [Pre, Synch,"1"]
serin2 PORTB.3, baud, [WAIT(Synch),in]
if (in == "1") then
high PORTB.4
pause 250
low PORTB.4
pause 250
endif
goto main
I compiled your code but I got this error:
--> opcode expected instead of '__config'
Please help.
