## 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.

## Interface
|
|
|
|
|
|
|
|
|
|
The following functions are implemented:
|
|
|
|
|
|
2021-12-22 07:38:25 -05:00
|
|
|
- **Optoma(HardwareSerial\* stream = &Serial)** constructor, default uses Serial,
|
2021-01-29 06:31:58 -05:00
|
|
|
other HW or SW Serial are possible.
|
2021-12-22 07:38:25 -05:00
|
|
|
- **void init(int ID, uint32_t baudRate = 9600)** default baud rate = 9600.
|
2021-01-29 06:31:58 -05:00
|
|
|
The ID is used to address a specific beamer.
|
2021-12-22 07:38:25 -05:00
|
|
|
In theory one could have multiple beamers on one RS232 port (never seen or tested).
|
|
|
|
|
- **uint32_t getBaudrate()** return set baud rate.
|
|
|
|
|
- **void switchOn()** idem.
|
|
|
|
|
- **void switchOff()** idem.
|
|
|
|
|
- **bool isOn()** idem.
|
|
|
|
|
- **void increaseVKS()** VKS - Vertical KeyStone. check datasheet.
|
|
|
|
|
- **void decreaseVKS()** VKS - Vertical KeyStone. check datasheet.

## Future
|
|
|
|
|
|
|
|
|
|
- More functionality will be added on a need to basis.
|
|
|
|
|
- Create examples.
