ESP32, PWM channel issues #6275
Description
Seems the ESP32 use the same channel for all pwms.
>>> import machine
>>> pw1 = machine.PWM(machine.Pin(0))
>>> pw2 = machine.PWM(machine.Pin(14))
>>> print(pw1, pw2)
PWM(0, freq=5000, duty=512) PWM(14, freq=5000, duty=512)
>>> pw1.freq(1000)
>>> print(pw1, pw2)
PWM(0, freq=1000, duty=512) PWM(14, freq=1000, duty=512)
Reading the pwm code for the esp32 port, it should use instead a map of an available channel per pin.
