Event Boilerplate Code
Posted: Thu Aug 13, 2020 10:07 am
I'm using events to signal some changes to my statemachine running in its own thread, I might as well use messaging or direct signaling but events seems to work well.
The thing that bothers me is the amount of boilerplate I have to write to add a single event. (Code is an excerpt from different files in my program)
Having 4 or 5 different COMMANDS for the state switches makes that process produce a lot of boilerplate code. Am I doing something wrong? Maybe theres a better tool for this that I'm missing

Code: Select all
// declare eventsource
EVENTSOURCE_DECL(es_inverter_init);
//make available in header file
extern event_source_t es_inverter_init;
//declare enum for event mask
typedef enum {
COMMAND_INIT
}
// event listener in thread
event_listener_t init_listener;
//map listener to event source and enum
chEvtRegisterMask(&es_inverter_init, &init_listener, EVENT_MASK(COMMAND_INIT));
//Send event from other thread
chEvtBroadcast(&es_inverter_init);
//receive event somewhere else
eventmask_t evt = chEvtWaitAny(EVENT_MASK(COMMAND_INIT);
//decide to do something
if(evt & EVENT_MASK(COMMAND_INIT)) { return some other state; }
