Sx dsp

william chan

Hi All,

Has anyone tried using the SX as a voice DSP chip?
Is the SX fast enough to sample voice sounds ( using the 2-pin AtoD method ) to store in some ram and then
play back to an amplifier ( using PWM ) ?

Thanks.

Dear Peter,

The SX52 MMC project on sxlist.com has files .sch and .brd
What software can I use to view them?

Thanks a lot.

I have no idea, but since the PCB are listed to be from
Alberta Printed Circuits try
http://www.apcircuits.com/resources/downloads/easytrax.zip
as found on the Alberta website.

.sch and .brd are file extensions for EaglePCB, a free PCB board layout program.

Came accross this:

Not sampling audio, but playing audio from RTTTL formatted sounds (ringtones)

Although the code is in C, it is simple enough to manually translate to SX assembly or SX/B.
