Re: [ts-7000] SPI - TS7500

humm, right.
Did I just send words of 8bits? How would send 24?

The question of the pin ready, I'm doing manually at first.

What else could it be?

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>

Hello, I'm making a statement of my ts7500 "kit" with an ADC by SPI.
Someone tell me if I'm doing something wrong? He always returns the same three characters. The code is below. The ADC is the AD7193.

//part 1:
sbuslock();
setdiopin(33, 0); ////out 1 down  'CS on'
sbusunlock();
system("spictl -c 10000 -e 1 -w 10:040110:08:280001");
