Mit diesem Tool können '''lua''' Dateien auf einen ESP gespielt werden.
== Interface ==
* Seriell
* TCP

== Beispiel ==
Beamer mit neuer Lokig bespielen
./programESP.sh 10.23.xx.xx beamer_init.lua init.lua
Paanik wir können nur noch über die Serielle Schnittstelle mit dem ESP reden:
sudo ./programESP.sh serial beamer_init.lua init.lua
== Quellcode ==
<pre>
#!/bin/bash

DEVICE=/dev/ttyUSB0
SLEEPTIME=0.2
TCPPORT=2323

echo ""
echo "The flash logic can be done via ethernet or serial"
echo "The first filename is mandatory!"
echo ""
echo "The second filename is the filename on the LUA devic."
