The Firmware is completely based on Sming Framework for ESP8266 and is hopefully easy to use.
I will upload some binaries which you can upload without the compiling.
Formerly i use this firmware and its options for my SmartHome integration with ioBroker from where I script everything i want to control or measure. And it isn't completely ready, so if you want to contribute something ...

Connect jumper wires to all 5 Pins of the first MAX7219 Display board (On the side where Data In is printed on PCB) and connect the other ends of the jumper wires to the corrosponding pins like described in the table below.
| LED Matrix | ESP8266 |
|---|---|
| VCC | +3.3V |
| GND | GND |
| DIN | GPIO13 (HSPID) |
| CS | Choose free GPIO, e.g. GPIO2 |
| CLK | GPIO14 (HSPICLK) |
You have more than one option to flash the ninHOME Node Firmware.
esptool.py -p /dev/ttyUSB0 -b 230400 write_flash -ff 40m -fm qio -fs 4m 0x00000 0x00000.bin 0xa000 0xa000.bin 0x52000 spiff_rom.bin
After flashing the ninHOME Node Firmware and starting up your ESP8266 it won't find any configuration in the SPIFFS so it
will open up a Wifi Access Point which you can connect to, if you havent changed the name in the source it will be called 'ninHOME Configuration'.
After you connected to the Access Point you can open up a Browser and got to (if not changed in source)
There you find an overview of the reachable Wifi Networks.
Click on your desired network and give in the Wifi Password, after that reset your ESP8266.
Now your ninHOME Node should be connected to your choosen Wifi Network,
the IP of it you can find in your Router or if you open up a Serial Monitor on the ESP8266.
A more easy way will be implemented soon.
Hi, I tried to flash your bin's into one of my Wemos D1 mini (4 MB). But I get errors from esptool.py. It says "Detected overlap at address 0x52000". If I try to Flash a single bin after another, I can Flash it, but it will not work. Can you tell me how to flash into my Wemos D1 mini?
i am trying to flash this to Nodemcu esp8266 but i canot get it to work can i get help
very nice project and exactly what im looking , but im not really good on this .. can you share the binary ..or somehow direct me to a instruction . (sorry my knowledge is on network only) ..thanks
