We are porting known good working 'C31 code into a 'VC33 design and cannot establish functionality of timer0. Otherwise, everything else has worked across the two designs as expected. Even timer1 will operate in both designs. Are there any known issues with 'VC33 timer0? _____________________________________

Hi all, I'm using the VC33 University DSK to sample sound and display a frequency spectrum. I have created some code mostly made up of existing code included with the VC33 DSK CDROM. The code uses a fairly simple RINT routine to sample the sound into an array. After sampling the sound I'm running an FFT/Windowing routine based on fft256b.asm. A graphpoint is setup after windowing

If I'm doing something like repetitive calculations on matrices, it would be...
