Multiple HALs

[jandelgado]

I'll provide an example showing how to drive built-in ESP32 PWM's and an PCA9685 driver in the next days.

[troky]

Driving PCA9685 (creating new HAL) is not a problem. I want to have std::list of different HAL types.

[jandelgado]

Could you please provide an example what the exact problem is (code)?

[troky]

There is no (abstract) base class/interface that coul be used.
For example: I need std:: list<JLedBase*>() where list elemnts can be JLed, JLed, etc... so I can cast JLed to JLedBase and call JLedBase->On() function etc...

[jandelgado]

There is intentionally no base class to keep the memory footprint low. But coincidentially I am working on a feature allowing to stuff different objects like JLed objects or JLedSequence objects recursively into a JLedSequence. I'll try to provide a branch that you can test in the next days.

[troky]

Well, for test, I de-templated your TLed class and made it abstract adding two virtual functions: analogWrite() and millis() and now I can create derived class from public TLed and implement those two funcions just like you do it in separate hal class. Problem solved... now I can have std::list<TLed *>()
