15 // Overview: |
|
16 // Test millisecond timers |
|
17 // API Information: |
|
18 // NTimer |
|
19 // Details: |
|
20 // - Create and start a number of periodic timers, verify results are |
|
21 // as expected. |
|
22 // - Attempt to start a timer that has already been started. Verify returned |
|
23 // error results. |
|
24 // - Start one shot interrupt and one shot DFC timers and verify that the |
|
25 // delay time is correct. |
|
26 // - Start additional one shot interrupt timers with various values and verify |
|
27 // results are as expected. |
|
28 // - Calculate and print the elapsed time. |
|
29 // - Start some timers, display min. max, avg and count information on each. |
|
30 // Verify results are as expected. |
|
31 // - Cancel a periodic timer and reuse it in a variety of conditions. Time how |
|
32 // long it takes for each to complete. |
|
33 // - Perform some random timer tests and display the results. |
|
34 // - Check idle time while a variety of one shot timers run. Verify results are |
|
35 // within the expected range. |
