Someone can help me how configure it?
Because the code work only if put the RS232-USB.
but i when put the max232... the pin RX no work. |

Post a link to a schematic of your connections between the PIC and the
Max232.
How to post an image on the CCS forum:
Go to this website:
http://postimage.org/
Upload your image. Select family safe. Then click the first button for
"Hotlink to Forum" to get a link to the image.
Then go to the CCS forum and type Ctrl-V to paste the link into a post.
If postimage.org doesn't work in your country, then use Google to find
another free image hosting site for forums. |

the problem is not the max (i think), i am sure that the problem is the register... but i no know configure it.
The code work good with usb-ttl to each side... but when i connect the module wifi, the code work, but the pin RX no work :( ..
this guy find the solution

I just want to end this. I think it's some kind of Proteus bug and I don't
want to deal with it. So, I installed an 18F45K22 (same PIC family) in
my PicDem2-Plus board. I compiled the program shown below with
CCS compiler vs. 5.035. I loaded TeraTerm and typed random characters
into the terminal. It echoes them back. It's working:
This is with UART1 on pins C6 and C7, as your schematic shows.
If you think it's the CCS compiler, then post your compiler version.
It's given at the top of the .LST file, which is in your project directory
after a successful compilation. I'll test it with your version.

the code works fine, but when I connect the module wifi... block the pin the Uart2 RX or RX of the uart that I use. just as there
http://www.microchip.com/forums/m542631.aspx Why?
If I only connect the Tx pin and then i wait and connect Rx, it works well.
But if start all at the time, block the RX pin.
Why if i Use this, yes work without problem?: TTL/USB (Uart1) ---- PIC---- TT/USB (Uart2)

Please post the make/model of the 'wifi' module you're using.
i suspect it's the all too common 5 volt PIC - 3 volt peripheral problem.

If Rx is blocked, the first thing to do is add the ERRORS parameter. Example:
| Quote: |
#use rs232(baud=9600,bits=8,parity=N,xmit=PIN_C6,rcv=PIN_C7, ERRORS, stream=uart1)
#use rs232(baud=9600,bits=8,parity=N,xmit=PIN_B6,rcv=PIN_B7, ERRORS, stream=uart2)

#use rs232(baud=9600,bits=8,parity=N,xmit=PIN_B6,rcv=PIN_B7, ERRORS, stream=uart2)
