ESP8266 Community Forum

- Wed Nov 12, 2014 9:16 pm #2525 Hello!

I want to make a project using the esp-01 but I'm not 100% sure it's possible. My question is: can you control an RGB led using it's gpio pins? I know it has 2 gpio pins (one used for firmware updates) and a rst pin (which on other websites is marked as gpio16). Can the rst pin be used as a regular gpio pin?

Thanks,
Bogdan

the RST pin is not an GPIO pin !

where do you see that it is GPIO16 ?

regards

EDIT:
Even on this forum, I found this article viewtopic.php?f=5&t=28
In the specs, you can see that there are 3 GPIO ports.

I don't have an ESP8266 yet, so that's why I need your help with this.

- Sat Nov 15, 2014 12:11 pm #2684 in the datasheet, GPIO16 is stated at the pin 8 of the chip, which is "XPD_DCDC : deep sleep wakeup"
and pin 32 of the chip is called EXT_RSTB : external reset signal

i'm not at my desk to verify on the ESP01 module, but i'm pretty sure that it is not GPIO16 pin, between CH_PD and VCC
