this API is a simple async API for GPIO.

Sets up a channel for read or write. Must be done before the channel can be used.
- channel: Reference to the pin in the current mode's schema.
- direction: The pin direction, pass either
'in'
for read mode or'out'
for write mode. - edge: Interrupt generating GPIO chip setting, pass in
'none'
for no interrupts,'rising'
for interrupts on rising values,'falling'
for interrupts on falling values or'both'
for all interrupts.
Defaults to'none'
.
Writes the value of a channel.
- channel: Reference to the pin in the current mode's schema.
- value: Boolean value to specify whether the channel will turn on or off.
Reads the value of a channel.
- channel: Reference to the pin in the current mode's schema.
Tears down any previously set up channels. Should be run when your program stops, or needs to reset the state of the pins.
Emitted when the value of a channel changed. Sometimes call continuously with same value.
- channel: change channel. Sometimes not changed.
- value: Changed value.
This have rpi-gpio like API in rpiGpio
property.
