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. driver/dht: Use mp_raise_OSError helper function. 2016-10-07T02:53:34+00:00 Damien George damien.p.george@gmail.com 2016-10-07T02:53:34+00:00 urn:sha1:e3d29996b3d0b1a81bd3dcc1d139e0a6ee233b03 extmod: Add machine time_pulse_us function (at C and Python level). 2016-05-31T12:58:48+00:00 Damien George damien.p.george@gmail.com 2016-05-31T12:58:48+00:00 urn:sha1:4940bee62a636f7e2653a4d4eeac5071448addc0 The C implementation is taken from the DHT driver. drivers: Add C-level function to read DHT11 and DHT22 devices. 2016-05-26T16:10:06+00:00 Damien George damien.p.george@gmail.com 2016-05-26T16:10:06+00:00 urn:sha1:48a7ef0576f9c1cb71a07d1c01183b3872e2f762 Uses mp_hal_pin API.
