Delivery Inspection / Function check

Steps for function check

  • Connect all tentacles via USB with the computer

  • Connect all tentacles via Octobus

  • Pulseview:

    • Start pulseview: sudo ./pulseview-NIGHTLY-x86_64-debug.appimage

    • 1 M samples/ 16 MHz

    • Raising edge trigger on D0

    • 5% pre trigger

    • I2C-SCL: D2

    • I2C-SDA: D3

  • Run the tests:

pytest -v -s \
      --firmware=pytest_args_firmware_RPI_PICO2_v1.24.0.json \
      tests/test_simple.py::test_i2c_pattern

Expected text output

========================================== 2 passed in 7.15s ==========================================

pytest -v -s \

Note

If these test succeed:

  • The configuration file testbed_ch_wetzikon_1.py contains the correct serial numbers.

  • The tentacles * are correctly connected and work. * are connected correctly via the Octobus

  • The tentacles MCUs etc. are soldered correctly
