Yegor Yefremov 14486f0e9e tests/periph_uart: add automated testing script

Add automated script to test devices against known testers.

Tests performed:

* echo test
* extended echo test i.e. received byte value will be incremented
* tester's register access

How To Run

Connect the DUT (device under test) UART6 to the BPT (bluepill tester). Information for BPT setup can be found here.

Example Test With Nucleo-F401RE

Flash the periph_uart firmware on the nucleo-f401 with make BOARD=nucleo-f401 flash in the periph_uart directory
Connect the BPT to the cpu using a USB to Serial converter
(BPT IF_TX = PA9)
(BPT IF_RX = PA10)
Connect the BPT to the DUT
(DUT RX/PA12 <=> BPT TX3/PB10)
(DUT TX/PA11 <=> BPT RX3/PB11)
test.py requires the path to $RIOTBASE/dist/tests to be added to PYTHONPATH environment variable. Either modify PYTHONPATH permanently in the .bashrc or modify it temporary before invocation:
PYTHONPATH=$PYTHONPATH:$RIOTBASE/dist/tests python3 test.py
Run the test.py from the periph_uart/tests directory (with various options)
python3 test.py for python 3
python3 test.py --log=DEBUG to see all debug messages
python3 test.py --dut_port="/dev/ttyACM0" to specify the port
python3 test.py --log=DEBUG --dut_port="/dev/ttyACM0" --dut_uart=6 --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_uart -> DUT UART number to test
--bpt_port -> the port name of the BPT
