Hi to all, I'm new to the arduino environment, I own an arduino due, I made some experiments with interrupts, apparently I cannot get the frequency higher than 250kHz, is this a known limit of the hardware ? I'm missing something, I read the datasheet and it states that TC_CMR_TCCLKS_TIMER_CLOCK1 is 84MHz / 2 = 41MHz so I was hoping that setting appropriately RA and RC (in my case 20 and 41 respectively) I would be able to acquire timer interrupts at 1MHz frequency.
Where am I wrong ?
Thanks in advance,
Giuseppe
