2.3 MASTER AND SLAVE MODULES: ( SUMMARY)

 

 
 

 

MASTER 

SLAVE 

It places the address at the head of the data packet  
 

 RF 

No 

Yes 

It removes the address from the data packet head 
 

 RS232 

No 

Yes 

It verifies the destination address 

No 

Yes 

It verifies the checksum 

Yes 

Yes 

Internal address 

 0 

 
 
 

3. Programming                        

 
The WIZ2 modules may be programmed through the serial port, by closing the jumper 3 and supplying, 
subsequently, the module. 
 
The programming mode foresees to enter a WRITE or READ type command. 
 
Here below is reported the list of the registers, their addresses and functions. 
 
 
 

 REGISTER’S 
 NAME 

ADDRESS  FunCTion 

 

DEFAULT 

 ADDRESS 

$00 

 WIZ2 module’s address 

$00 

 RS232 

$03 

 RS232 protocol options: 
 00: no parity 
 01: odd parity 
 02: not in use 
 03: even parity  

$00  (no parity) 

 
 
 

3.1 WRI TE 

 
The WRITE command enters a value in a register of the microcontroller’s internal EEPROM,  contained in the 
WIZ2 module. 
 
Format:

 

 
#_<address_register>_<value_register> 

 
The programming string is composed by a 3 bytes sequence: 
 

• 

‘#’: ASCII type $23 which enables the microcontroller to receive a command of a register writing. 

• 

<address_register>: is the register’s address to be written 

• 

<value_register>: is the register’s new value
