User Manual
EVB90601 Configuration Board
The commands are 2-character alphanumeric strings. The arguments are 1-byte (0-255),
alphanumeric strings in HEX radix. Additional special symbols such as space intervals, commas,
dots, etc. can be placed between the command and arguments in order to make the statements
more readable and understandable. The only restriction is one statement to be not longer than 30
bytes (characters). The commands and arguments are 2 characters long. The leading zeros of
arguments are also required. For example the argument ‘0x0B’, should be written as ‘0B’. If the
zero is missed and it is entered as ‘B’, the firmware will accept it as ‘B0’. All missing arguments
are accepted as ‘00’. For example the command ‘rd 00 00’ can be shorten to ‘rd’. But the
command ‘wr 00 0A 0B’ CANNOT be entered as ‘wr 0A 0B’, because, in this case, it will be
recognized as ‘wr 0A 0B 00’.
If the arguments passed to some command are not sufficient (for example the command needs 3
arguments, but only 2 are supplied), 0x00 replaces the missing arguments. If the arguments
passed to some command are more than required, only the necessary arguments are considered.
The rest of them are just skipped.
The interface is NOT case sensitive! The entered commands and arguments could be either lower
or upper case.
If the commands are typed manually (using any standard terminal emulation program) and a
typing mistake is encountered, the entire command statement can be removed by pressing the
ESC button. The last typed symbols could be removed also by pressing the BACKSPACE
button.
The commands are passed for processing after sending of the <CR> symbol (ENTER button).
All the returned values by the EVB are also in text format (ASCII symbols) and can be read by
any standard terminal emulation program. The numbers returned are in HEX radix.
Commands List
The EVB recognizes the following commands:
1. Reading the micro-controller registers. This also includes the special purpose registers and
micro-controller ports. The microcontroller PIC18F252 uses 12 bits to address its data memory
and special function registers
Syntax:
rd
address MS byte
address LS byte
command
argument 1, HEX byte
argument 2, HEX byte
argument 3, HEX byte
argument 4, HEX byte
Return Value:
One HEX byte (2 chars) with the contents of the specified register<CR>.
