=====Wiring method=====

{{:modularfaduino:cfdi-16.png?nolink |}}
===== Setting the module's address =====
 * Up to 8 CFDI-16Bs can be used in one system with different address settings of 0~7.

{{ :modularfaduino:dip_sw_0x00.png?nolink |}}
=====How to use the API=====

1. <html><code>#include "CFMEGA.h"</code></html> library registration 

2. CFNET object creation: ''CFNET **object name**'' =>'' CFNET ** cfnet;**''

3. Call the function(s): ''**Object name**.digitalRead();'' => ''**cfnet**.digitalRead(0);''
\\
====-u16 digitalRead(u8 address);====
The input status of the entire specified address module is read as a 16-bit value.

  * address: module dip switch value (0~7)
====-bool digitalRead(u8 address, u16 pin); ====
Returns the state of a single pin as a boolean value. (1 bit read)

  * ''address'': The address of the module as configured by its DIP switch (0~7)
  * ''pin'': Pin index (0 ~ 15)



<code c>
#include "CFMEGA.h"

CFNET cfnet;

void setup() {
 Serial.begin(9600);
}

void loop() {

 u16 blockK0 = cfnet.digitalRead(0);
 bool portIn0 = cfnet.digitalRead(0, 0);

 Serial.print("Block0 : "); Serial.print(blockK0, HEX);
 Serial.print(" PortIn0 : "); Serial.print(portIn0,HEX);
 Serial.print("\n"); delay(200);
}
