I want to deploy a gumstix with an A/D convesion capability. Our needs are:
24 bit D to A at about 30 kHz
16 bit A to D at about 1kHz
6x1 bit 5V switches
I can build a cirucit and connect to the serial ports however there
appear to be some expansion boards such as Robostix which might do this.
After playing "dungeons and dragons" with the web pages for some time, I
cannot find an appropriate engineering datasheet for the gumstix
expansion boards. I need the usual engineering information discussing
A/D register width, slew rates, phase delay etc etc.
Can anyone point me to the data sheets for the expansion boards. Also I
would be interested in any experiences that people have had interfacing
gumstix devices for this purpose
