user49652: I'd like to control some digital ICs with a ESP8266-12.

How can I switch 2 pins to HIGH in the same moment?
How can I switch one to LOW and the other to HIGH in the same moment?
Is it possible with every port or only with grouped ports and how are the groups?


user31105: See the datasheet: esp8266-technical_reference_en
Paragraph 2.2.2 shows how to use the output registers.
With the registers GPIO_OUT, GPIO_OUT_W1TS and GPIO_OUT_W1TC you can set or clear multiple GPIOs.
