3.29 Sound Test program | 3 Tests and Diagnostics | |
Subtest02 | Sine Wave |
|
| This subtest is executed by loading the COM file (ADSIN.COM). The program | |
| expands sine wave data table from 16KB to 64KB, and creates the play data. Then | |
| it transfers the data between the DMA and the CODEC to play the sine wave. (It | |
| sounds like a continuous beep). By using wave measurable devices such as an | |
| oscilloscope, the data can be measured as a sine wave. |
|
| When the subtest is executed, the sine wave is played while expanding sine wave | |
| from 16KB to 64KB. |
|
| The display returns to the Sound (Standard) test menu after the test ends. | |
Subtest03 | Line IN recording & play |
|
| This subtest executes the same test as the subtest01 by recorded sound from the | |
| different port |
|
For more details on the subtest, refer to the subtest01 Microphone recording & play.
The display returns to the Sound (Standard) test menu after the test ends.
