I have hooked my HX711 to an ESP8266. I'm now faced with the problem that once I put my ESP into deep sleep mode the GPIO Pin which is hooked to the PD_SCK pin goes low.
This in turn will put the HX711 in "normal mode".
When PD_SCK Input is low, chip is in normal working mode. (Page 5)
How can I keep both devices in power down mode?
When PD_SCK pin changes from low to high and stays at high for longer than 60µs, HX711 enters power down mode.
I tried to pull up the PD_SCK pin and use the ESP8266 gpio pin as a drain but that did not work. Maybe I did something wrong.
I could introduce an inverting 74xx chip but that just seems wrong. Is there maybe something I overlooked?
