i am new in ARMs, new in Kinetis and new in Processor Expert.
I try to setup the clock system of this Evaluation system. To test the setup i want to toggle a pin in the main function. But i cannot see a clean toggle signal. An other idea was to toggle the pin in an timer interrupt. If i choose Period of 100 Khz, i can see a clean toggle signal on the oscilloscope. If i change the period to 50 Khz or 1 Mhz i cannot see a clean signal.
Does anybody an idea what's going wrong?
Thanks in advance!
