Custom equalizer settings

[Michsior14]

Some time ago I've implemented equalizer presets and thought about adding custom equalizer settings (eg. via e param).

I could easily use get_data_from_parameter from dev.c to get the content of buffer that would represents it, but how to handle the different parameter type in handle_feature (int param)? Just by introducing another one that would be optional char* stringParam or struct holding different types? How you would like to handle it @Sapd?

In fact I did not thought about that when writing the function.

I think best way would be to change the parameter of handle_feature from int param to void* param and call it with ie. &sidetone_loudness then cast it depending on the case in handle_feature .

It also might make sense to parse the equalizer parameter directly in main.c with something like get_data_from_parameter and pass it with such a struct to the device_found->

// defined in device.h
struct equalizer_settings {
    int size;
    int equalizer_parameter_list[];
};

If you want to use get_data_from_parameter it might make sense to move it from dev.c/h to utility.c/h
