ESP8266 / ESP32 driving an LED Matrix Module (16x16) with running the editor in the webbrowser, hosted by the ESP
(A simple version of the editor is available online at http://www.io-expert.com/ledmatrixeditor)
As soon ESP is booted the first time, a Wifi AP is generated:
Wifi AP: EspLedMatrix
Password: EspLedMatrix
The Web-UI can be launched by navigating to http://esp-led-matrix.local or http://192.168.4.1.

The firmware can be installed via the esptool utility. There are two different releade binaries existing:
- vX.X_esp32_esp-led-matrix.bin for ESP32
- vX.X_esp8266_esp-led-matrix.bin for ESP8266 or ESP8285
See also https://github.com/schreinerman/esp-led-matrix/releases/ for current available binaries.
The esptool can be installed via pip:
python3 -m pip install esptool
To programm an ESP8266 or EPS8285, following command can be issued: (for firmware version v1.0, COM-Port /dev/tty.SLAB_USBtoUART)
python3 -m esptool --port /dev/tty.SLAB_USBtoUART \
--baud 115200 \
write_flash 0x0 \
v1.0_esp8266_esp-led-matrix.bin
To programm an ESP32, following command can be issued: (for firmware version v1.0, COM-Port /dev/tty.SLAB_USBtoUART)
python3 -m esptool --port /dev/tty.SLAB_USBtoUART \
--baud 115200 \
write_flash -z 0x1000 \
v1.0_esp32_esp-led-matrix.bin
