# Optoma
|
||
|
|
|
||
|
|
Arduino library to control Optoma W305ST beamer over RS232.
|
||
|
|
|
||
|
|
## Description
|
||
|
|
|
||
|
|
The Optoma library contains functions that help to control
|
||
|
|
the beamer from an Arduino.
|
||
|
|
|
||
|
|
The library is tested with an UNO and an Optoma W305ST Beamer.
|
||
|
|
The commands can work on other Optoma Beamers
|
||
|
|
|
||
|
|
Command structure
|
||
|
|
```
|
||
|
|
~XXnnn parameter
|
||
|
|
|
||
|
|
~ start command
|
||
|
|
XX 2 digit ID
|
||
|
|
nnn command can be up to 3 char/digit
|
||
|
|
space space
|
||
|
|
param parameters, depend on command
|
||
|
|
\r end command
|
||
|
|
```
|
||
|
|
|
||
|
|
## Interface
|
||
|
|
|
||
|
|
The following functions are implemented:
|
||
|
|
|
||
|
|
- **Optoma(HardwareSerial = Serial)** constructor, default uses Serial,
|
||
|
|
other HW or SW Serial are possible.
|
||
|
|
- **init(ID, baudrate)** default baudrate = 9600.
|
||
|
|
The ID is used to address a specific beamer.
|
||
|
|
In theory one could have multiple beamers on one RS232 port (never seen or tested)
|
||
|
|
- **switchOn()** idem
|
||
|
|
- **switchOff()** idem
|
||
|
|
- **increaseVKS()** VKS - Vertical KeyStone
|
||
|
|
- **decreaseVKS()** VKS - Vertical KeyStone
|
||
|
|
|
||
|
|
## Future
|
||
|
|
|
||
|
|
- More functionality will be added on a need to basis.
|
||
|
|
- Create examples.
|
||
|
