3.29 Sound Test program
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 (Line-in 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.
