8266 GPIO pins and pull-down configuration

Using Arduino Programming Questions
1

Hi,

Most of the GPIO pins on the 8266 have internal pullup resistors. There are hints that pull-downs maybe possible as well GPIO — ESP8266 RTOS SDK Programming Guide documentation

Has anyone done this? And if so, can it be done in the Arduino environment or do I need to go another level deeper?

Thanks,

David Duehren

According to the documentation on the ESP8266 pulldown is only supported for pin 16 (for that you cannot activate a pullup). But you can simply configure it using the pinMode() call.
