Maxim DS2408 1-Wire 8-Channel Addressable Switch
-------------------------------------------------------------------------------
This is a set of example captures of the 1-Wire traffic from a Maxim Integrated
(previously Dallas Semiconductor) DS2408 1-Wire Addressable Switch.
Details:
https://datasheets.maximintegrated.com/en/ds/DS2408.pdf
Logic analyzer setup
--------------------
The waveform data was acquired using Rigol DS1074Z oscilloscope.
Because of the currently unresolved libsigrok bug #1364 it can't be acquired
directly using rigol-ds, so it was obtained using external tool and then
loaded into PulseView with "Import Raw analog data without header".
This method is described here:
https://skyboo.net/2019/03/using-rigol-ds1074z-oscilloscope-under-linux-and-pulseview/
disable-test-mode.sr
--------------------
This is the special "Disable Test Mode" command which should be issued on the
power-on, for reference read "Power-up timing", page 38 of the datasheet.
channel-access-write.sr
-----------------------
A successful command for setting PIO outputs (channel access write).
channel-access-write-fail.sr
----------------------------
Same command as above but the device is responding with 'Fail New State' (0xff)
which informs about the error.
read-pio-registers.sr
---------------------
A function for reading device registers (where a target address is given).
In this example the address 0x89 is read (PIO output-latch state register).
