Building a WiFi Gateway using ESP8266:
Indication leds: the same pin can be used. Pro: only one pin is needed. Con: you won't be able to see the type of indication. An alternaive, if you can't find enough pins, is to only activate one or two.
Inclusion: hopefully someone else can assist. I have never used inclusion.
It's working now!
I'm using the following pins for the leds:
// Flash leds on rx/tx/err
// Led pins used if blinking feature is enabled above
#define MY_DEFAULT_ERR_LED_PIN 0 // [D3 / GPIO 0] Error led pin (Red)
#define MY_DEFAULT_RX_LED_PIN 2 // [D4 / GPIO 2] Receive led pin (Green)
#define MY_DEFAULT_TX_LED_PIN 16 // [D0 / GPIO 16] Send led pin (Yellow)
The leds where on all the time except when there was some activity, so I had to invent the leds:
// Inverses the behavior of leds
#define MY_WITH_LEDS_BLINKING_INVERSE
For the inclusion button I've used:
// Digital pin used for inclusion mode button
#define MY_INCLUSION_MODE_BUTTON_PIN 5 // [D1 / GPIO 5] Button pin
I needed to use an pull up resistor (10K ohm) for more stability.
