EC_DigitalIn(GPIO_TypeDef *Port, int pin)

Create a DigitalOut connected to the specified pin.

Parameter

• int pin: DigitalOut pin to connect to. 0~31

• Port: GPIOA~GPIOH

int read ()

Return the output setting, represented as 0 or 1 (int)

void write ( int _outVal)

Set the output, specified as 0 or 1 (int)

Parameters

• int _outVal: An integer specifying the pin output value, 0 for logical 0, 1 for logical 1
