tests, pyb: Add 'import pyb' when needed. 2014-05-04 07:40:51 -04:00			`import pyb`

run code formatting script 2021-03-15 09:57:36 -04:00			`if not hasattr(pyb, "DAC"):`

tests: Convert remaining "sys.exit()" to "raise SystemExit". 2017-06-10 13:14:16 -04:00			`raise SystemExit`
tests/pyb: Adjust tests so they can run on PYB and PYBLITE. A few tests still fail on PYBLITE, and that's due to differences in the available peripheral block numbers on the different MCUs (eg I2C(2) exists on one, but it's I2C(3) on the other). 2017-02-05 21:48:01 -05:00
tests: Add a suite of tests specifically for the pyboard. 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/. 2014-05-03 11:43:27 -04:00			`dac = pyb.DAC(1)`

stm32/dac: Add buffering argument to constructor and init() method. This can be used to select the output buffer behaviour of the DAC. The default values are chosen to retain backwards compatibility with existing behaviour. Thanks to @peterhinch for the initial idea to add this feature. 2018-04-10 08:25:55 -04:00
