tests, pyb: Add 'import pyb' when needed. 2014-05-04 07:40:51 -04:00			`import pyb`
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			`from pyb import I2C`

tests/pyb: Refactor pyboard tests to work on PYBv1, PYBLITEv1 and PYBD. 2019-12-13 00:43:17 -05:00			`# test we can correctly create by id`
			`for bus in (-1, 0, 1):`
tests: Add tests to create valid and invalid UART, I2C, SPI, CAN busses. 2015-05-28 06:06:12 -04:00			`try:`

stm32: Replace master/slave with controller/peripheral in I2C and SPI. Replace "master" with "controller" and "slave" with "peripheral" in comments, errors, and debug messages. Add CONTROLLER and PERIPHERAL constants to pyb.SPI and pyb.I2C classes; retain MASTER and SLAVE constants for backward compatiblity. 2021-06-12 00:53:44 -04:00			`i2c.init(I2C.CONTROLLER, baudrate=400000)`
