- Define test_utils_interactive_sync as DEFAULT_MODULE in Makefile.tests_common
- For tests disabling autoinit, add test_utils_interactive_sync to main
- Add DISABLE_MODULE += test_utils_interactive_sync for tests requiring
sudo, `tests/shell`, `tests/minimal` and `tests/stdin`
- Add shell_commands to tests/periph_wdt and tests/struct_tm_utility to
pull `r` and `s` commands
- Remove includes and usage in `tests/main.c` for tests that where
already using test_utils_interactive_sync
- Since `printf()` is buffered it might not arrive in a single
read to pexpect. Regex which terminate in a group match might
match only some elements, this might break tests that depend
on exact group matching.
The string formatter initially used doesn't seem to be supported by the AVR toolchain. Correctly closing the buffer with a null byte and using plain %s formatter works in all cases
- Use standard RIOT style `ina2xx_params_t` on initialization as explained in
[1] instead of a custom API
- Provided a default configuration via `ina2xx_params_t` as required by [1] that
works fine for the INA219 breakout board and with an optimal resolution that
still covers the whole range of USB high-power devices (500 mA @ 5V) with a
comfortable safe margin.
- Changed initialization procedure to include a device reset and connectivity
test, as required by [1]
- The calibration value is now calculated by the driver
- This simplifies using the driver a lot
- The user can still choose a trade-off between range and resolution that
matches the application requirements, but now among predefined values
- This allows the driver to easily convert the raw data into meaningful
physical data, as the resolution of the raw data is known
- All measurements are provided as meaningful physical data as required by [1]

The INA219 has the exact same interface as the INA220 (including values and
semantics of the configuration register). Thus, this driver can be used for
both. The ina220 has been renamed to ina2xx to reflect this and pseudo modules
for the ina220 and ina219 have been added.
