2020-03-30tests: Format all Python code with black, except tests in basics subdir.David Lechner
This adds the Python files in the tests/ directory to be formatted with ./tools/codeformat.py. The basics/ subdirectory is excluded for now so we aren't changing too much at once. In a few places `# fmt: off`/`# fmt: on` was used where the code had special formatting for readability or where the test was actually testing the specific formatting.

2016-11-11stmhal/i2c: Add option to I2C to enable/disable use of DMA transfers.Damien George
New keyword option in constructor and init() method is "dma=<bool>". DMA is now disabled by default for I2C transfers because it currently does not handle I2C bus errors very well (eg if slave device doesn't ACK or NACK correctly during a transfer).
