H A D | hx711.c | 68d8ab3c Mon Sep 09 07:37:48 CDT 2019 Andreas Klinger <ak@it-klinger.de> iio: adc: hx711: optimize performance in read cycle
Set gain in hx711_reset() to its default value after a reset cycle. This omits one precautionary read cycle, because the read is performed in hx711_set_gain_for_channel() anyway if gain has changed.
Check for DOUT low and if its high wait some time if it goes down instead of doing a blind reset cycle when DOUT is not down.
This is a performance optimization which allows to query the sensor with a higher frequency.
