- 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
Once the terminal software is connected, click the Reset button on the Feather HUZZAH ESP8266 board to reset it and
have it print out the welcome message:
If you don't get this message, first check that the red/blue leds flickered when you press the reset button. If they didnt,
make sure you've got the right baud rate selected in the software (9600)
Hello world!
Ok we can now turn on an LED. There is a red LED on each board, connected to GPIO #0
NodeMCU Lua's pinouts are not the same as the Arduino/gcc pinouts. We print the Arduino pinouts on the
board so watch out!
The Lua documentation for the ESP8266 has GPIO #4 and #5 swapped so if #4/#5 aren't working for you, try
swapping!
