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:

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)

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):

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)
