Decoder for standardized messages from the JEVOIS smart camera (http://jevois.org)

Data are extracted from a serial link and produce a JEVOIS_MSG ABI message

Example for airframe file

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

<module name="jevois">
  b'<define name="JEVOIS_SEND_MSG" value="FALSE|TRUE" />\n  '
  b'<configure name="JEVOIS_UART" value="UARTX" />\n    '
  b'<configure name="JEVOIS_BAUD" value="B115200" />\n    '
</module>

Module configuration options

Configure Options

name: JEVOIS_UART value: UARTX
Description: UART on which Jevois camera is connected
name: JEVOIS_BAUD value: B115200
Description: UART Baudrate, default to 115200

Define Options

name: JEVOIS_SEND_MSG value: FALSE|TRUE
Description: Send synchronized jevois message over telemetry link, use periodic report function otherwise

Module functions

Init Functions

These initialization functions are called once on startup.

jevois_init()

Event Functions

These event functions are called in each cycle of the module event loop.

jevois_event()

Periodic Functions

These functions are called periodically at the specified frequency from the module periodic loop.

jevois_report()
- Frequency in Hz: 5
- Autorun: FALSE
  Periodic function is started by user command.
jevois_send_state()
- Frequency in Hz: 4
- Autorun: TRUE
  Periodic function automatically starts after init.
