Somebody recently asked mmiscool for a driver for the i2c TMI637 4 digit 7-segment display so they could display the IP address - it's a cheap and convenient display which is equally useful for a clock or timer or counter, so I hope something materialises... and I wouldn't be surprised if it was already on TrackerJ's (Mr I2C) ToDo list.
But in the meantime perhaps someone may find this LED IP 'Blinker' of use.
It blinks out the sequences of IP digits with appropriate pauses between the 4 numbers, and because a blank '0' non-event isn't helpful, a zero is denoted by 10 blinks.
By default it uses the onboard gpio01 blue led (can be configured for others) so the example script will run on just about anything.
Some notes:
If BlinkIP is ran at program startup it will be noticed that no screen writes occur until after BlinkIP finishes and the program continues on to the WAIT instruction. This does not matter of course, because if you already knew the IP address in order to connect via browser you wouldn't be needing to blink the led to discover it.
It may be useful to BlinkIP on demand by pressing a local button. Be aware that any gpio button that doesn't already include a pull-up resistor will need to have a pullup physically added... but I strongly advise against adding physical resistors to the likes of Sonoff and Electro-dragon modules with potentially lethal MAINS voltages in close proximity.
The Sonoff hardware button already includes an on-board hardware pullup, but the button may already be being used for manually toggling the relay, in which case you could use the button in MultiMode whereby the same button can be used for different purposes depending on how long it is pressed.
In the example, a short press of less than 2 seconds does a Toggle, but if the button is held down for 2 seconds or longer it does a BlinkIP.
Notice that whatever the Toggle state, after BlinkIP finishes, the led is returned to it's original state - so if the led was showing the status of the relay, it will still show correct relay status again after BlinkIP.
If you join up all the dots you'll see that besides being a BlinkIP example, plus button MultiMode example, this is actually a complete self-contained network relay node with local button activation and led status indication which you could obviously also control however you wish... whether by date/time, local button or switch or sensor activation, or remotely-triggered. Change ledpin = 13 if used on a Sonoff.
