Ameba MicroPython: [RTL8722CSM] [RTL8722DM] GPIO

API Documents
Constructors
Pin(“pin_name”[required], direction[required], pull_mode[optional], value[optional])
Create a Pin object associated with the given gpio pin name and configure it using other parameters. This allows you to then read/write digital values on the pin.
• “pin_name”: The name of the pin, must be in string format, use help(Pin.board) to check all pin names
• direction:
 -Pin.IN – for input
 -Pin.OUT – for output
• pull_mode:
  -Pin.PULL_NONE – no pull-up or down resistor
 -Pin.PULL_UP – enable pull-up resistor
 -Pin.PULL_DOWN – enable pull-down resistor
 -default value – Pin.PULL_NONE
• value: Initial value, only applicable to OUTPUT, for example value = 1. Default value 0
Methods
Pin.id()
This method will return the associated GPIO pin name after declaring a Pin object.
 
Pin.init(“pin_name” [required], direction [required], pull_mode [optional], value [optional])
Identical function as the Constructor, it creates and initializes a Pin object using parameter typed in.
 
Pin.value(number[optional])
This method can be used in 2 ways,
1. Output number keyed in
 number can only be either 0 or 1 , indicating logic 0 or logic 1.
2. Check the status of the pin
 When left blank, this method will check the status (logic 0 /1) of the Pin, regardless of which direction this Pin is configured as.
 
Pin.on()
This method sends a logic 1 signal to the associated pin
 
Pin.off()
This method sends a logic 0 signal to the associated pin
 
Pin.toggle()
This method toggles the logic signal of the associated pin
