I'm using Linaro running on a MicroZed board to talk to the AD3961. I'm initially trying to use the Linux drivers to get the data from the internal temperature sensor. I tried to follow the example shown on page 84 of the AD9361 Reference Manual.
I was able to find these adi equivalents in /sys/kernel/debug/iio/iio:device0
| SPI Address | data | adi equivalent |
|---|---|---|
| B | 0 | echo 0 > adi,temp-sense-offset-signed |
| C | F | echo 1 > adi,temp-sense-periodic-measurement-enable |
| D | 0 | echo 1000 > adi,temp-sense-measurement-interval-ms |
| F | 0 | echo 256 > adi,temp-sense-decimation |
| 1D | 1 | ?? |
| 35 | 1E | echo 30 > adi,ctrl-outs-index |
| 36 | FF | echo 255 > adi,ctrl-outs-enable-mask |
If I understand things correctly, this should set up a 1000ms periodic internal temperature measurement.
So my questions:
- How can I read the temperature values (Address: 0x00E) from the command line?
- How do I set the Aux-ADC config (Address: 0x01D)?
- How would I set it up to manually start a temperature reading? (setting bit in Address 0x00C)?
- Is it just a matter of setting adi,temp-sense-measurement-interval-ms to zero, and then setting adi,temp-sense-periodic-measurement-enable to 1 to start the reading?
