Two questions about my project:UDP communication and RS-232

[huangkai]

Dear everyone:

     Recently I am doing a project.This is based on MQX system.The hardware system is K60N512.I try to setup a simple udp communication between an UDP client on my PC and the K60 tower.I hope that someone can give me an exapmle.I hope the compilation environment is IAR.The second question is about RS-232 communication.I want set a communication between PC and K60 tower by RS232.I am a rookie.So I hope someone can give me these two examples.    

     Thank you!

Hello,

First follow the MQX Getting Started document to build MQX libraries for your board. There is IAR workspace file prepared for that:
c:\Freescale\Freescale_MQX_4_0\config\twrk60n512\iar\build_libs.eww

For simple communication between PC and MQX via RS232 check this example:
c:\Freescale\Freescale_MQX_4_0\mqx\examples\hello2\
IAR project file:
c:\Freescale\Freescale_MQX_4_0\mqx\examples\hello2\iar\hello2_twrk60n512\hello2_twrk60n512.ewp
just "Add existing project..." from the IAR Project menu.

For UDP server there is the example in RTCS User's Guide, section 3.30 Quote of Day server.

Dear Sir:

Thank you very much.Because of your help,the UDP communication has succeeded.But RS-232 doesn't work. So I want know if you can give me another example.

Thank you again.

Yours sincerely,

Huang Kai

Check that you're looking at the right COM device.

Usually for BSP's, the default stdin/stdout/stderr files are routed to OSJtag on the processor board, which provides serial-to-usb CDC class (this enumerates with Host PC as a virtual serial port).

If you wish to use TWR-SER RS232, you will need to define BSP_DEFAULT_IO_CHANNEL configuration to "ttyd:" file on TWR-K60N512, and build BSP and PSP libraries with this configuration.

Thank you!The problem has been solved!

Hello huang kai,

any example which contains this function call printf is a good starting point for you. Anyway, you should start with hello world example.

Please, read Getting started, precisely chapter n. 7 (how to properly jumper your board). That chapter includes information about default console.

Regards,

MartinK
