Sample time error when CAN Pack block has constant block input
显示 更早的评论
I am trying to generate C code using a simple model that uses a CAN pack and CAN unpack block. A constant block feeds into the CAN pack block. I ran into the following build error:
The sample time of output port 1 of block 'test_TSnew/CAN Pack1' is constant, yet its data type is 'CAN_MESSAGE';
the sample time of an output port may be constant only if its data type is stored in a builtin type.
If the block has an input port, consider placing a Zero Order Hold block at the input port, to force a non-constant sample time.
Alternatively, if this block is an S-Function, consider using the option SS_OPTION_DISALLOW_CONSTANT_SAMPLE_TIME

This is intended behavior. A "CAN Pack" block requires a non-continuous sample time. To remove this error, set the constant block’s “Sample time” to a discrete value instead of “inf”. You may double-click on each constant block to set its “Sample time”. This explicit requirement on the "CAN Pack" block began in R2016b.
