m52233demo

[jonasb]

hey, I'm new here, I want to use multiple demo boards as a client to sent data to a server pc but I dont have a clue to start. I can not chance the flash software in the board. And I don't know how to implement the stack in the board.

Please help.

It's for education purpose.

You can download the free Special Edition of CodeWarrior for ColdFire from this web site. It's limited, but can compile enough code so that you can experiment and learn what to do. Also, the installation has code examples that you can study. Specifically, you want to study the startcf.c file, which does the stack setup and run-time environment initialization. HTH.

If you just want to get a telnet(ish) client running on the M52233DEMO and talk to it with a command-line, I have a skeleton source code project that you might have luck starting from.

It is at: http://www.cpustick.com/downloads/skeleton.zip

You'll need CW 7.1 installed, and then open project.mcp, select the Skeleton 52233 target, and build it.  You can then edit skeleton/skeleton.c to intercept the command-line requests.  Then flash it to the DEMO board.

You connect to the M52233DEMO board using a telnet/hyperterm to raw TCP/IP port 1234 at the board's DHCP address.

If you want something even simpler, you can just flash StickOS to the DEMO board (download from http://www.cpustick.com/downloads.htm) and run it and then log into the MCU using telnet/hyperterm as above.

With StickOS, you can then write a BASIC program to manipulate the 52233 pins/peripherals right in your terminal emulator, save it, run it, and collect data, etc., and send it back to your PC thru "print" statements...

For example, to gather accelerometer data is simply:

You can also connect to either the skeleton project or StickOS using the DEMO board's RS232 connection -- just set your terminal emulator to 9600 baud, 8 data bits, no parity, and xon/xoff flow control.  Press <Enter> to get a command prompt.
