In the body of your ReadNow.readDone() event you would want to post a task that then signaled your Read,readDone() event. Your application wouldn't receive the results at exactly 2 kHz (because of the delay in posting the task and the scheduler actually running it), but the samples should be

I'm trying to get the Oscilloscope application read samples from an ADC input at 2kHz. This required a finer-grained timer then the millisecond-based timer originally in the application. Unfortunately, I haven't seen a 32kHz implementation of the Timer interface for the msp430 platfrom. But, I
