3.27 Sound/LAN/Modem Test Program

Subtest 02

Sin Wave

 

 

 

This subtest is executed by loading the COM file (ADSIN.COM). The

 

program expands sin 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

 

measuring devices such as an oscilloscope, the data can be measured as a sine

 

wave.

 

 

 

When the subtest is executed, the following message appears:

 

....Press test number[1-4] ? pause

 

 

Press any key to continue...

 

 

 

Press any key, and the following message appears. Then sin wave is expanded

 

from 16KB to 64KB data and is beeped.

 

 

....Press test number[1-4] ? call sin
