BosFn

A very simple wrapper for the BrainOS functions.

All of the methods are designed for internal use, and are not meant to be used by the user. The user simply has to declare a function and add it to the bosFns list.

Inner Workings

There are two types of BosFn functions, ones that return a boolean, and ones that don’t. BosFn functions that return a boolean have the ability to remove themselves from the BrainOS function list if they return true. Also, all BosFns are first called with a true parameter, and then with a false parameter every other time. This is so that the user can use the parameter to remake lvgl objects, because they are deleted when the screen is switched.

Usage

To use a BosFn, the user just needs to declare a function, then add it to the bosFns list

void myBosFn(bool remake){
    //drawing code here
}
int main(){
    BosFn::addNewFn(myBosFn);
}

For lvgl functions, the user MUST use the remake parameter to make lvgl objects. Also, the bosFn functions as both a first drawing function, then as an animation function. Because of this, the user does not need to make any seperate lvgl animations to move the object around.

void myBosFn(bool remake){
    static lv_obj_t* myObj;
    if(remake){
        //create lvgl objects here
        myObj = lv_obj_create(lv_scr_act());
    }
    //do any object animation code here
}
int main(){
    BosFn::addNewFn(myBosFn);

    thread brainOSThread = thread(BosFn::runBrainOS);
}
