ADC Problem in MQX Example for Kwikstik

Hi. I'm using Codewarrior 10.1 with the lastest update, MQX 3.7 and

Kwikstik Patch. (I have a Kwikstik REV 4)

I'm trying to use the MQX example relative to ADC converter, but it not work correctly. The various printf in the example doesn't work.

If I make a Debug, it blocks after a printf (where I set a breakpoint). Exactly in io_read.c in this part of the code.

#if MQX_CHECK_ERRORS
if (dev_ptr->IO_READ == NULL) {
file_ptr->ERROR = MQX_IO_OPERATION_NOT_AVAILABLE;
return(IO_ERROR);
} /* Endif */
#endif

Can you give me a solution?

Thanks

Hi. I have already resolved this problem, commenting out line 75 of "fio.h" and recompiling PSP and BSP.

Happy Critsmas! :smileyhappy:
