User-defined PX4 uORB messages

Hello everyone,

I want to use a user-defined PX4 uORB message with the hardware support package.

When I try to run the model, I get the following error.

MATLAB System block 'test/PX4 uORB Write/SinkBlock' error occurred when invoking 'setupImpl' method of 'px4.internal.block.Publisher'. The error was thrown from '

'C:\ProgramData\MATLAB\SupportPackages\R2023a\toolbox\target\supportpackages\px4\+px4\+internal\+block\Publisher.p' at line 151

'C:\Program Files\MATLAB\R2023a\toolbox\target\codertarget\sltoolstrip\m\+codertarget\+internal\+sltoolstrip\ConnectedIOHandler.m' at line 106

'C:\Program Files\MATLAB\R2023a\toolbox\target\codertarget\sltoolstrip\m\+codertarget\+sltoolstrip\EmbeddedHardwareBoardContext.m' at line 493'.

Caused by:

• The class px4.internal.ConnectedIO.uORBMsgMap has no Constant property or Static method named 'actuator_motors_simulink'.

I checked the class px4.internal.ConnectedIO.uORBMsgMap and saw that my custom message is not in there. Is there an update function for that?

Best regards

Simon

Custom uORB messages are not supported with Connected I/O currently. You can consider using the Monitor and Tune Simulation instead.
