Writes rotation to the uart bus

Meant for sending the rotation to the ODROID board or to the stereo camera boards. Can be used to improve vision algorithms. The protocol that is used is the stereocommunication protocol.

Example for airframe file

Add to your firmware section: This example contains all possible configuration options, not all of them are mandatory!

 <module name="stereocam_state2camera">
   <configure name="STEREO_UART" value="UARTX" />
   <configure name="STEREO_BAUD" value="BXXXXX" />
 </module>

Module configuration options

Configure Options

name: STEREO_UART value: UARTX
Description: Sets the UART port number of the connected camera (required)
name: STEREO_BAUD value: BXXXXX
Description: Sets the BAUD rate of the connected camera (required: must be same as camera)
