jaybird3rd Posted March 14, 2012 Share Posted March 14, 2012 If the mini expander is bidirectional then with suitable voltage conversion you could bit-bash an SPI interface to an SD card. The speed wouldn't be brilliant but you could get it down to a relatively low cost design. Yes. Or even an FTDI bridge chip like the FT245R for a USB interface to a PC. That would be especially useful for development, since it would make it easy to download code to a real Aquarius for testing. Much more convenient than burning EPROMs. Quote Link to comment Share on other sites More sharing options...
