Note
:
<address_register> and <value_register> have to be intended as binary values. For instance: the value ‘4’
has to be understood as an integer number (binary configuration 00000100) and not as an ASCII type “4”
which corresponds to a decimal value 52 whose binary configuration is 00110100.
It is suggest to pay attention to the conversion between decimal values and ASCII types.
The WIZ2 “packing system” does not utilize sequences of
escape
types, therefore it places, at the user
disposal, the 256 combinations of the ASCII 8 bits coding.
3.2 READ
The READ command reads the register’s value of the microcontroller’s internal EEPROM, contained in the
WIZ2 module.
Format:
$_<address_register>
The programming string is composed by a 2 bytes sequence:
•
‘$’: ASCII type $24 which enables the microcontroller to receive a command of a register reading
•
<address_register>: is the address of the register to be read.

3.3 PROGRAMMI NG PROCEDURE
The module programming, takes place by closing the jumper 3 before supplying the module.
The data packet containing the programming word shall not be forwarded to the remote module.
The programming procedure takes place at the speed set by the jumpers 1 and 2, and at the correct parity.
The WIZDEMOx software is pre-set at a 9600 b/s speed without parity bits.
3.4 REGI STERS
Here below is reported the list of the registers utilized for the WIZ2-434-x modules and their functions.
