Most of the framework is implemented. Most noticable is the missing analogWrite. While analogWrite is on it's way, there are a few other options that you can use:
- 16 channels [LEDC](cores/esp32/esp32-hal-ledc.h) which is PWM
- 8 channels [SigmaDelta](cores/esp32/esp32-hal-sigmadelta.h) which uses SigmaDelta modulation
- 2 channels [DAC](cores/esp32/esp32-hal-dac.h) which gives real analog output
