telemetry_transparent module

Telemetry using PPRZ protocol over UART

Currently used as a makefile wrapper over the telemetry_transparent subsystem

Example for airframe file

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

1 <module name="telemetry_transparent">
2  <configure name="MODEM_PORT" value="UARTx" />
3  <configure name="MODEM_BAUD" value="B57600" />
4 </module>

Module configuration options

Configure Options

  • name: MODEM_PORT value: UARTx
    Description: UART where the modem is connected to (UART1, UART2, etc)
  • name: MODEM_BAUD value: B57600
    Description: UART baud rate

Auto-loaded modules

The following modules are automatically loaded (just as if you had added them in the airframe file)

  • module__telemetrynps
  • module__telemetrysim

Module functions

Init Functions

These initialization functions are called once on startup.

Event Functions

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


Header Files

The following headers are automatically included in modules.h
