nodemcu devkit 1.0 should have gpio9 available when flashing in DIO mode.

When I try to set the output to high or low.. the device resets.
I'm not using LUA firmware, but if it also fails in nodemcu lua, then is a HW thing.

Anyone tried and has it working?
Thanks

TWO MORE GPIO (9,10) IN ESP01 MODULE [SOLVED]

Actually in some cases setting it as a zero will turn something on seems strange but this can be seen by turning on and off the led on board which if I recall correct was pin 3 or 4 I think well just check out some resources my guess is you are confused about GPIO and pin ... In the program you use the pin # to set the corresponding GPIO...

Anyways hope this helps...

Hi forlotto,
I'm using right pin. SD D2 is printed on the board, that is pin 11 that is gpio9.

This requires DIO flash mode.
What is your environment (windows,linux, mac) and flashing tool/mode?

thanks for the link, I checked, but in this case the device should support and no HW hacks should be needed.

thanks
