- ESP8266 F.A.Q.
- When I connect stuff to some of the pins, the Huzzah stops working. Whats up with that?
- My Huzzah board keeps crashing and resetting, whats up with that?
- I can't seem to find the Serial port on my computer for the Feather HUZZAH?
- I still can't seem to find the Serial port on my computer for the Feather Huzzah!
- So, I’m getting a 'no such file' error compiling for ESP8266 on my Mac
- Whenever I start or reset the ESP8226 there's a bunch of "gibberish" on the Serial console
- I'm having difficulties uploading to the HUZZAH with the Arduino IDE
- I tried that, but I'm still having difficulties uploading with the Arduino IDE
- I'm stuck in bootloader mode and can't upload
- I can't get Lua to respond to my commands
