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.
As per the machine.UART documentation, this is used to set the length of
the RX buffer. The legacy read_buf_len argument is retained for backwards
compatibility, with rxbuf overriding it if provided.
In non-blocking mode (timeout=0), uart.write() can now transmit all of its
data without raising an exception. uart.read() also works correctly in
this mode.
As part of this patch, timout_char now has a minimum value which is long
enough to transfer 1 character.
Addresses issue #1533.
UART object now uses a stream-like interface: read, readall, readline,
readinto, readchar, write, writechar.
Timeouts are configured when the UART object is initialised, using
timeout and timeout_char keyword args.
The object includes optional read buffering, using interrupts. You can set
the buffer size dynamically using read_buf_len keyword arg. A size of 0
disables buffering.
In tests/pyb is now a suite of tests that tests the pyb module on the
pyboard. They include expected output files because we can't run
CPython on the pyboard to compare against.
run-tests script has now been updated to allow pyboard tests to be run.
Just pass the option --pyboard. This runs all basic, float and pyb
tests. Note that float/math-fun.py currently fails because not all math
functions are implemented in stmhal/.
