1 micro second time unit LPC2106

Bruno Silva

Greetings,

I would like to put the timer to interrupt the LPC2106 CPU on a multiple of 1 microseconds. I got success with a range of 1 millisecond, but at intervals of 1 micro the error is very large, about 40%, one has any idea how to shorten this interval?

Best regards

    If set up properly, the timer interval is independent of instructions executed in the ISR. As long as the ISR execution time doesn't exceed the interval Bruno should be fine.

    I think Bruno said that the granularity was supposed to be one microsecond -- not the duration of interval. But then, the problem description was not very clear to begin with.
