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:

 - Battery management chip: X-Powers AXP199
  * I²C slave address: 0x34/52 (shifted: 0x68/104)

 - RTC chip: Hec Semiconductor H8563S
  * I²C slave address: 0x51/81 (shifted: 0xa2/162)

 - Digital Thermal Orientation Sensor (DTOS): MEMSIC MXC6225XU
   * I²C slave address: 0x15/21 (shifted: 0x2a/42)


trekstor_ebr30_a_i2c_0x15.sr
----------------------------

The logic analyzer used was a ChronoVu LA8 (at 4MHz):

  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 and trekstor_ebr30_a_i2c_120s.sr
------------------------------------------------------------

This is a 30s/120s dump of the I2C traffic while the device was attached
to USB.

The logic analyzer used was a Saleae Logic (at 4MHz):

  Probe       I2C pin
  -------------------
  4 (orange)  SCL
  6 (green)   SDA

The sigrok command line used was:

  sigrok-cli -d 0:samplerate=4mhz --time <time>
             -p '4=SCL,6=SDA' -o <filename.sr>

(<time> was 30s or 120s)
