Wiring method
Setting the module's address
* Up to 8 CFDI-16Bs can be used in one system with different address settings of 0~7.
How to use the API
1. <html>
#include "CFMEGA.h"
</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)
