Wierd code problem.

Tomshao Sarapoot

Hi guys,

I've been stucked for hours. It is a project for CORTEX-MX, the compiler I am using is KEIL in PRO mode.

Here is a segment of C code:

================================================================== case COMMAND_STATE_WAIT_WAVELENGTH: Request.wavelength = val; datacount++; if (Request.wavelength>128) { *cmderr = COMMAND_ERROR_DATALENGTH; command_state = COMMAND_STATE_ABORT; } else if (Request.wavelength ==0) { command_state = COMMAND_STATE_WAIT_CHECKSUM; } else { command_state = COMMAND_STATE_WAIT_DATA; }

break;
==========================================================

After compile,it turns into something else and it doesnt work.

I I changed "Request.wavelength>128" to "Request.wavelength+1>128+1", and it worked a bit better. >_<!

Please HELP.
what a miracle~~

    The functionality of your code all depends on what's happening to the "val" variable which is outside the scope of your code snippet: the value is "val" is stored in Request.wavelength which then determines the path through teh rest of the code snippet.

    Have you tried checking the code that writes to "val"?
