ESP8266 Digital Pins not working

[Oscar Rodas]

I´m working with a NodeMCU 8266.

I tried to use your digital pin setup and doesn´t work on pins 12,13,14 & 15.

I tried with your analog set up and it works.

Can you check what could be happening.

We changed the pin numbering for the ESP8266 to use the D0-D8 labels that are printed on most, if not all, ESP8266 boards:

Thus, pins 12, 13, 14, and 15 are now pins 6, 7, 5, and 8.

Unfortunately, there were two bugs in the first version of the pin redirection code. Those were fixed in v0.6.5, so make sure you’ve updated the firmware on your board to that version or later and everything should work as expected with the new pin numbers.

Hello guys, the software is amazing. I and my kids are enjoying a lot. But since I updated the firmware the pins stopped working. I looked for a solution all over. I spend one day looking for the answer above… Could I suggest that you place the information in the ESP8266 information page at: https://microblocks.fun/nodeMCUSetup? Will make life easier.

Thanks a lot!

Excellent idea! I will up date that page!
