Member Function Documentation

bool NexGpio::analog_write	(	uint32_t	port,
		uint32_t	value
	)

writes an analog value (PWM wave) to a pin

Parameters

port	- the gpio port number
value	- the duty cycle: between 0 (always off) and 100 (always on).

Returns

true if success, false for failure

uint32_t NexGpio::digital_read

(

uint32_t

port

)

read a HIGH or a LOW value to a digital pin

Parameters

port	- the gpio port number

Returns

the value from a specified digital pin, either high or low

bool NexGpio::digital_write	(	uint32_t	port,
		uint32_t	value
	)

write a HIGH or a LOW value to a digital pin

Parameters

port	- the gpio port number
value	- HIGH or LOW

Returns

true if success, false for failure

uint32_t NexGpio::get_pwmfreq

(

uint32_t *

number

)

read pwm output frequency

Parameters

number

- the frequency

Returns

true if success, false for failure

bool NexGpio::pin_mode	(	uint32_t	port,
		uint32_t	mode,
		uint32_t	control_id
	)

Set gpio mode

Parameters

port	- the gpio port number
mode	- set gpio port mode(0–Pull on the input 1–the control input binding 2–Push-pull output 3–pwm output 4–open mode leakage)
control_id	- nextion controls id ,when the modeel is 1 to be valid

Returns

true if success, false for failure

bool NexGpio::set_pwmfreq

(

uint32_t

value

)

writes pwm output frequency

Parameters

value

- the frequency: between 1 and 65535

Returns

true if success, false for failure
