Hi, everyone. I am pretty new to embedded systems design, and have a simple question about letting PC to generate SPI signal. Are there any evaluation board that can enable personel computer to generate SPI signal?
Besides, right now I have a project for simple control signal. Are there any general procedures for such project development? Any information will be welcomed.

If you could find old PC with LPT port you could use it to make SPI interface.
other slow solution is to use RS232 port with RS232-TTL level traslator.
You could use Tx as SCLK, RTS and DTR line as DATAOUT and CHIPSELECT, and CTS for DATAIN.
But SPI speed would be about 1 kilobyte/sec at RS232 115200bps.
