Unfortunately, `common_hal_pulseio_pwmout_get_duty_cycle` will return a value very close to, but not exactly, the value passed to `common_hal_pulseio_pwmout_set_duty_cycle`. If the frequency is modified without the calling code also re-setting the duty cycle then the duty cycle will decay over time. This fixes that problem by tracking the unadjusted duty cycle and re-setting the duty cycle to that value when the frequency is changed. wrong arg type for PWMOut variable_frequency 2019-03-13T01:28:30+00:00 Dan Halbert halbert@halwitz.org 2019-03-13T01:28:30+00:00 urn:sha1:97140e6a62770bf60c0cca9967960bbc038e8991 Fix SYNCBUSY loop typo. 2019-03-01T04:38:26+00:00 Dan Halbert halbert@halwitz.org 2019-03-01T04:38:26+00:00 urn:sha1:3c24e893e98d158f939a8dba11c4b7783d998500 Use TCC LUPD lock when updating CCB 2019-03-01T00:53:35+00:00 Dan Halbert halbert@halwitz.org 2019-03-01T00:53:35+00:00 urn:sha1:808304e8276a51a6ec2ac69e6f33a908c756f722 handle 'set_timer_handler' on this side, vs samd-periphs. 2019-02-20T02:18:21+00:00 sommersoft sommersoft@gmail.com 2019-02-20T02:18:21+00:00 urn:sha1:55e7c5a41bf53fc44bfdbedd9f1228241a62132c moves 'shared_timer_handler' back to atmel-samd from samd-peripherals 2019-02-17T01:54:16+00:00 sommersoft sommersoft@gmail.com 2019-02-17T01:54:16+00:00 urn:sha1:dafc370d22b0598f7330d907e7fbeaa4aa93cc15 Rudamentary backlight support 2019-01-31T19:42:14+00:00 Scott Shawcroft scott@tannewt.org 2019-01-26T02:31:27+00:00 urn:sha1:69bc5e189baef183918dc21dadaacf55ce66bee3
