ESP Wordclock

Setup

Initial Setup

Install the firmware on the ESP: The ESP must be set into the bootloader mode, like this

The firmware can be downloaded with the following script:

cd os/
./flash.sh ttyUSB0

Connect to the ESP via a terminal emulator like screen using a baud rate of 115200. Then format the filesystem and reboot the ESP with the following commands:

file.format()
node.restart()

Then disconnect the serial terminal and copy the required files to the microcontroller:

./tools/initialDietFlash.sh /dev/ttyUSB0

Install the optional packages:

./tools/initialDietFlash.sh /dev/ttyUSB0 mqtt.lua
./tools/initialDietFlash.sh /dev/ttyUSB0 ds18b20.lua

Upgrade

Determine the IP address of your clock and execute the following script:

./tools/remoteFlash.sh IP-Address

Hardware Setup

Mandatory:

GPIO2 LEDs
GPIO0 Bootloader (at start)
GPIO0 factory reset (long during operation) Optinal:
ADC VT93N2, 48k light resistor
GPIO4 DS18B20 Temperatur sensor
