6 - Logic Analyzer: Tektronix TLA 613
8 - Ubuntu 12.04 (Precise Pangolin)
10 - 1-Wire master: home made from:
11 - PL2303 (USB to UART)
12 - DS2480B (UART to 1-Wire)
17 Two thermometers were attached to the bus (only the data line was connected,
19 - DS28EA00 (1-Wire Digital Thermometer with Sequence Detect and PIO)
20 - DS18B20 (Programmable Resolution 1-Wire Digital Thermometer)
22 The server was started as:
23 $ owserver -d /dev/ttyUSB0
26 Three dumps were created:
28 1) "owdir.sr" (samplerate = 1MHz)
29 A request to list devices connected to the bus was performed:
42 2) "DS18B20.sr" (samplerate = 1MHz)
43 A read temperathure request was performed for the specified device:
44 $ owread /28.9BCFC8000000/temperature
47 2) "DS28EA00.sr" (samplerate = 1MHz)
48 A read temperathure request was performed for the specified device:
49 $ owread /42.A8A603000000/temperature
53 Conversion from TXT to sigrok dumps:
55 The provided dumps were exported from Flextronix TLA 613 logic analizer as text
56 files. A simple Python script was used to convert this dumps first into a
57 binary file and then into a sigrok standard dump.
62 sigrok-cli -i owdir.sr -a onewire:owr=0
63 sigrok-cli -i DS18B20.sr -a onewire:owr=0
64 sigrok-cli -i DS28EA00.sr -a onewire:owr=0
