TrekStor eBook Reader 3.0 I2C
-------------------------------------------------------------------------------
This is a set of example captures of the I2C traffic on a TrekStor eBook
Reader 3.0 EBR30-a (Weltbild + Hugendubel Edition) device.
For details on the device see:
http://randomprojects.org/wiki/TrekStor_eBook_Reader_3.0_EBR30-a_(Weltbild_%2B_Hugendubel_Edition)
There are three chips which are connected to the main CPU's SCL/SDA pins.
So far, it's unknown which device is responsible for which I2C output.
trekstor_ebr30_a_i2c_0x15.sr
----------------------------
The logic analyzer used for capturing was a ChronoVu LA8:
Probe I2C pin
-------------------
1 (orange) SCL
7 (yellow) SDA
The sigrok command line used was:
sigrok-cli -d 0:samplerate=4mhz --samples 8388608 \
-p '2=SCL,8=SDA' -o trekstor_ebr30_a_i2c_0x15.sr
trekstor_ebr30_a_i2c_30s.sr
---------------------------
This is a 30 second dump of the I2C traffic while the device was attached
to USB.
The logic analyzer used for capturing was a Saleae Logic:
Probe I2C pin
-------------------
4 (orange) SCL
6 (green) SDA
The sigrok command line used was:
sigrok-cli -d 0:samplerate=4mhz --time 120s
-p '4=SCL,6=SDA' -o trekstor_ebr30_a_i2c_30s.sr
