Paul Sokolovsky	d5e9ab6e61	extmod/machine_pulse: Make time_pulse_us() not throw exceptions. machine.time_pulse_us() is intended to provide very fine timing, including while working with signal bursts, where each transition is tracked in row. Throwing and handling an exception may take too much time and "signal loss". So instead, in case of a timeout, just return negative value. Cases of timeout while waiting for initial signal stabilization, and during actual timing, are recognized. The documentation is updated accordingly, and rewritten somewhat to clarify the function behavior.	2017-02-05 14:20:17 +03:00
Damien George	e3d29996b3	driver/dht: Use mp_raise_OSError helper function.	2016-10-07 13:53:34 +11:00
Damien George	4940bee62a	extmod: Add machine time_pulse_us function (at C and Python level). The C implementation is taken from the DHT driver.	2016-05-31 13:58:48 +01:00
Damien George	48a7ef0576	drivers: Add C-level function to read DHT11 and DHT22 devices. Uses mp_hal_pin API.	2016-05-26 17:10:06 +01:00
