| | 21 | Probe I2C pin |
| | 22 | ------------------- |
| | 23 | 1 (orange) SCL |
| | 24 | 7 (yellow) SDA |
| | 25 | |
| | 26 | The sigrok command line used was: |
| | 27 | |
| | 28 | sigrok-cli -d 0:samplerate=4mhz --samples 8388608 \ |
| | 29 | -p '2=SCL,8=SDA' -o trekstor_ebr30_a_i2c_0x15.sr |

| | 35 | This is a 30s/120s dump of the I2C traffic while the device was attached |
| | 36 | to USB. |
| | 37 | |
| | 38 | The logic analyzer used for capturing was a Saleae Logic: |

| | 40 | Probe I2C pin |
| | 41 | ------------------- |
| | 42 | 4 (orange) SCL |
| | 43 | 6 (green) SDA |
| | 44 | |
| | 45 | The sigrok command line used was: |
| | 46 | |
| | 47 | sigrok-cli -d 0:samplerate=4mhz --time <time> |
| | 48 | -p '4=SCL,6=SDA' -o <filename.sr> |
| | 49 | |
| | 50 | (<time> was 30s or 120s) |
