HI,

I am unable to run the following example.. using code warrior 10.7, but others example where working just fine..

What I did is create a new Project using a MPC5674F, copy *.c to source, *.h to Project_Headers

Then I deleted in source folder:

-__ppc_eabi_init.c

-MPC55xx_init.c

-MPC55xx_init_debug.c

-MPC5674F_MVxA264_HWInit.c

It is now working, not sure what was wrong with it (I believe connecting both potentiometer fixed the issue..) However, I added a pin toggle in the eQADCA_FIFO0_EOQ_INT_handler and no matters what I do, when changing adc prescaler, it stay at 23Hz.. How can I increase the adc speed ?

Thanks

Just figured it out... The interrupt is taking too long to execute... The fix is to disable serial port printing

Thanks

Hi, which moment it goes into exception? From the very beginning or somewhere from main routine?
