Re: [ts-7000] SPI - TS7500

Not sure I know the system that well, but this is a slow converter.
According to the AD7193 data sheet, in single conversion mode, the
DOUT/RDY pin (or RDY bit)  indicates when the conversion is done.
Don't you have to check if conversion is done first before
reading?

Also, the spictl help indicates -w should be colon delimited hex octets.
Example from help:

./spictl -l 1 -w 0B:00:20:00:00 -r 32 <host><:port>
