Member Function Documentation

analogRead()

int CNanoI2CIOExpander::analogRead

(

int

input

)

A method tha return 10bits value of one of the 6 analog inputs...

Parameters

input

analog input number from 0 to 5

Returns

read value

Warning : mapping of analog inputs on ARDUINO Nano:

• 0 A0
• 1 A1
• 2 A2
• 3 A3
• 4 A6
• 5 A7

Definition at line 115 of file nanoI2CIOExpLib.cpp.

begin()

void CNanoI2CIOExpander::begin

(

int

add = 0x5F

)

function that start the I2C protocol with nanoI2CIOExpander

Parameters

add	the I2C address of the componant...

Returns

nothing

The default address of the componant is 0x58 Can be fixed from 0x58 to 0x59 with D12D10D11 pin of the Nano The only one adress pin D13 is pulled-down (so no connect value is 0)

Definition at line 28 of file nanoI2CIOExpLib.cpp.

digitalRead()

int CNanoI2CIOExpander::digitalRead

(

int

input

)

Well knonwn function digitalRead applie to nanoI2CIOExpander but...

Parameters

input

the number of the input

Returns

the read value

Warning

input number from 0 to 10 corresponding to D2 to D12 on the nano

Definition at line 79 of file nanoI2CIOExpLib.cpp.

digitalWrite()

void CNanoI2CIOExpander::digitalWrite	(	int	output,
		int	value
	)

Definition at line 88 of file nanoI2CIOExpLib.cpp.

pinMode()

void CNanoI2CIOExpander::pinMode	(	int	output,
		int	mode
	)

A method to set the pinMode but...

Parameters

output	from 0 to 10
mode	INPUT, OUTPUT or INPUT_PULLUP

Returns

nothing

Warning

input number from 0 to 10 corresponding to D2 to D12 on the nano

Definition at line 47 of file nanoI2CIOExpLib.cpp.

test()

bool CNanoI2CIOExpander::test

(

)

A special test method that use 2 special register to write and read and display on the Serial monitor results...

Returns

true if all test is OK (new in 2.1 lib)

first write 0x10 to register Test1 (reg add = 1) and write 0x12 to register Test2 (reg add = 2) and re-read the values and display them on Serial monitor
