Constructor & Destructor Documentation

Aio

(

long

pin

)

Aio Constructor, takes a pin number which will map directly to the board number

Parameters

pin	channel number to read ADC inputs

Member Function Documentation

int getBit

(

)

Gets the bit value mraa is shifting the analog read to.

Returns

bit value mraa is set return from the read function

int read

(

)

Read a value from the AIO pin. By default mraa will shift the raw value up or down to a 10 bit value.

Returns

The current input voltage. By default, a 10bit value

float readFloat

(

)

Read a value from the AIO pin and return it as a normalized float.

Returns

The current input voltage as a normalized float (0.0f-1.0f)

Result setBit

(

int

bits

)

Set the bit value which mraa will shift the raw reading from the ADC to. I.e. 10bits

Parameters

bits	the bits the return from read should be i.e 10

Returns

mraa::Result type
