Hello Team.
I am having a syntax error report when I compile this simple example Flowchart with a PIC18F4550 Selected as device.

The flow chart contains only a main and the slave service makro attached my flowchart

Please help me out

I am still having problems to install the driver on WIN10 however it worked in WIN7 (I am using WIN7 machine at the moment)

Hi Peter,

This should work correctly now. The Slave Macro property was empty, I've now populated this with the slave_service name of your service macro.

Hi Ben.

I am sorry I am trying to find my way through this

Thank for the updated Flowchart however it now complains that the RunsSlaveservice ()has to few parameters

I hope soon I will be off your neck with this !

Hi Peter,

Aha yes sorry your slave service macro has a byte parameter so this also has to be specified in the component properties.
