This simple application opens specified COM port at
specified baud rate. Then you can open any PCM WAV file (16bit only) and
start sending via COM port by pressing "play" button. HW data flow handling
is always turned on so if there is no HW connected or it does not work correctly
it should be automaticaly terminated in some 5 seconds (State: timeout ...).
HW and some other informations can be found here:
http://elektronika.kvalitne.cz/ATMEL/necoteorie/tutorial/AudioTest/I2Semulation/I2S_emulation.html
Baud rate should be defaultly set to 2MBd for this HW but you
can set any baud rate you want for other purposes. COM port number and baud rate can be
selected in "config.ini" file or in menu "Options->COM settings".
For described HW you have to use virtual COM port emulated by
FT232 USB-COM converter and it's necessary to set "lattency" to 1 or 2ms in
virtual COM port drivers!
