======CFDO-16N======

DC SINK output 16-point module, when turned on, the output is shorted to ground, and when turned off, it opens.

[[https://comfiletech.com/modular-faduino/cfdo-16n-digital-output-module/|View at our online store]].
=====Electrical specifications=====
  * Output Ports: 16 
  * Output operating voltage: 5~27VDC
  * Maximum output current: 120mA / 1 point
  * Isolation: No isolation
  * Maximum on/off cycle: approximately 1kHz (1000 times per second)


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

{{:modularfaduino:cfdo16n.png?nolink |}}

===== Setting the module's address =====

  * Up to 8 CFDO-16Ns can be used in one system with different address settings of 0x00~0x07.
  * CFDO-16N shares an address with CFDO-8R module. In other words, addresses already in use by CFDO-8R cannot be used.

=====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**.digitalWrite();'' => ''**cfnet**.digitalWrite(0, 0xffff);''
\\
====-void digitalWrite(u8 address, u16 data) ====

Turns the output 16 ports of the specified address module into On and Off states with 16bit data values. (16bit write)
  * ''address'': The address of the module as configured by its DIP switch (0~7)
  * ''data'': On/Off value between 0x0000 and 0xFFFF (16bit)


====-void digitalWrite(u8 address, u8 pin, u8 on_off) ====
Turns one port of the specified address module’s pin on or off. (1 bit write)
  * ''address'': The address of the module as configured by its DIP switch (0~7)
  * ''pin'': Pin index (0 ~ 15)
  * ''on_off'': 0 or 1 (0=off, 1=on)

<code c>
#include "CFMEGA.h"
CFNET cfnet;

void setup() {
 cfnet.digitalWrite(0, 0XFFFF); delay(1000);
 cfnet.digitalWrite(0, 0X0000); delay(1000);
}

void loop() {
 for(int i=0; i<16; i++){
 cfnet.digitalWrite(0, i, 1 );delay(100);
 }
 cfnet.digitalWrite(0, 0X0000); delay(1000);
}
