# ESP Wordclock
|
|
## Setup
|
|
|
|
### Initial Setup
|
|
Install the firmware on the ESP:
|
|
The ESP must be set into the bootloader mode, like [this](https://www.ccc-mannheim.de/wiki/ESP8266#Boot_Modi)
|
|
|
|
The firmware can be downloaded with the following script:
|
|
<pre>
|
|
cd os/
|
|
./flash.sh ttyUSB0
|
|
</pre>
|
|
|
|
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:
|
|
<pre>
|
|
file.format()
|
|
node.restart()
|
|
</pre>
|
|
|
|
Then disconnect the serial terminal and copy the required files to the microcontroller:
|
|
<pre>
|
|
./tools/initialDietFlash.sh /dev/ttyUSB0
|
|
</pre>
|
|
|
|
Install the optional packages:
|
|
<pre>
|
|
./tools/initialDietFlash.sh /dev/ttyUSB0 mqtt.lua
|
|
./tools/initialDietFlash.sh /dev/ttyUSB0 ds18b20.lua
|
|
</pre>
|
|
|
|
|
|
|
|
### Upgrade
|
|
|
|
Determine the IP address of your clock and execute the following script:
|
|
<pre>
|
|
./tools/remoteFlash.sh IP-Address
|
|
</pre>
|
|
|
|
## Hardware Setup
|
|

|
|
* GPIO2 LEDs
|
|
* GPIO0 Bootloader (at start)
|
|

Optional:
|
|
* ADC VT93N2, 48k light resistor
|
|
* GPIO4 DS18B20 Temperatur sensor
|
|
|
