Detect push button
|
|
|
|
This example detects a push button connected to pin 4 and sends the command
|
|
to the printer screen when the button is pressed.
|
|
|
|
The push button is connected to pin 4 and the LOW value is when the button
|
|
is pressed.
|
|
|
|
Put this script in the ESP3D flash file system and call it from the init script in
|
|
configuration.h.
|
|
#define ESP_AUTOSTART_SCRIPT "[ESP300]/FS/detectpush.lua"
|
|
|
|
You can also start it manually from the serial monitor by typing:
|
|
[ESP300]/FS/detectpush.lua
|
|
|
|
Be sure to have the following line comment out in the configure.h:
|
|
#define ESP_LUA_INTERPRETER_FEATURE
|
