Use this library freely with Arduino 1.6.5

firmware version

• boite_de_couplageV08 (Arduino ATU firmware)
• boitier_de_commandeV02 (Arduino remote CTRL firmware)

Installation

use liquid cristal i2c library

Usage notes

ATU depend of your I2C expander

MCP23008 expander :

#define mcpLRAdr 0x20    //adresse i2c mcp23008
#define mcpCRAdr 0x21

PCF8574 expander :

PCF8574 Address range is 0x20-0x27

PCF8574A Address range is 0x38-0x3F

#define pcfLRAdr 0x38    //address i2c PCF8574AT
#define pcfCRAdr 0x20    //address i2c PCF8574T

uncomment if you have an LCD display connected on ATU

//#define AFFLCD

uncomment for debug (in this case RS485 protocol is corrupted with debug function)

 //#define DEBUG_CMD
//#define DEBUG_SWR
//#define DEBUG_DBM

searchDelay 20 :without LCD connected direclty on ATU <br>

searchDelay 1 :with LCD connected direclty on ATU

#define searchDelay 20
//#define searchDelay 1
