Yegor Yefremov ff525eb354 dist/tests/if_lib: move testing infrastructure files to a stand-alone package 
Create if_lib package containing all the modules and adapt the *.py files
to import each other using the intra-package references.

The idea behind a package is to invoke test.py either by permanently
modifying PYTHONPATH in user profile via adding path to $RIOTBASE/dist/tests
or make temporary PYTHONPATH changes during the invocation:

PYTHONPATH=$PYTHONPATH:$RIOTBASE/dist/tests python3 test.py

Leave periph_i2c_if.py in the same folder as test.py as this file is
just a Python wrapper around periph specific main.c.

Update BPT memory map. Use definitions generated with the latest code
generator. Both routine names and mapping have changed.

How To Run

Connect the DUT (device under test) I2C0 to the BPT (bluepill tester). Information for BPT setup can be found here.

Example Test With Nucleo-F401RE

  1. Flash the periph_i2c firmware on the nucleo-f401 with make BOARD=nucleo-f401 flash in the periph_i2c directory
  2. Connect the BPT to the cpu using a USB to Serial converter
    (BPT IF_TX = PA9)
    (BPT IF_RX = PA10)
  3. Connect the BPT to the DUT
    (DUT SCL/D15 <=> BPT SCL1/PB6)
    (DUT SDA/D14 <=> BPT SDA1/PB7)
    (DUT NRST <=> BPT PB1)
  4. Run the test.py from the periph_i2c/tests directory (with various options)
    python test.py for basic tests with autoconnect
    python3 test.py for python 3
    python test.py --log=DEBUG to see all debug messages
    python test.py --dut_port="/dev/ttyACM0" to specify the port
    python test.py --log=DEBUG --dut_port="/dev/ttyACM0" --dut_baud=9600 --bpt_port="/dev/ttyACM1" > nucleo-f401_test.txt for all the fix'ns

Flags

--log=DEBUG -> allows for debug output
--dut_port -> the port name of the DUT
--dut_baud -> the baud rate of the DUT
--bpt_port -> the port name of the BPT

Notes

  • If no serial connection to the BPT the test should still be able to run, it just will not be able to reset.
  • Connect the SDA, SCL and if possible the DUT reset pin.
  • Autoconnect may work if no ports are specified.
  • Default baud rate is 115200
