The card must be connected to a computer host through the
interface RS232. The cordon of connection is equipped with two
females DB9 connectors wired in the following way:
One can find it in the business used for serial file downloading
between 2 computers.
On a PC, one can use " Terminal " application
of Windows or equivalent.
On a MAC, one can use " communication " application
of AppleWorks or amount.
In both cases, connection must be initialized in 9600 bits
by second with 8 bits of data, 1 bit of stop, without parity and
any control of stream.
The size of the screen must be fixed to 80 columns and function
" automatic return in the line " must be activated.
If all is OK, here is what must be shown after power up
of the card:
This window corresponds to an application of Terminal VT52
emulation with my system.
Type " VLIST " command as listing of the vocabulary
and you will obtain this:
" VLIST " command lists the vocabulary by beginning
with the last seized instruction and end by the first. Another
command, " DLIST ", lists the vocabulary in the alphabetical
order of instructions. This command exploits in fact the table
of the dictionary description of which is given in the page"Vocabulary
and memory". Here is the result of the execution of the
" DLIST " command:
Here is maintaining a demonstration of the interpreter /
compiler FORTH with the seizure of instructions described in the
page dedicated in"Real-time kernel". This allows to
discover " TLIST " command listing tasks administered
by the system:
The first utility to be compiled is telechar.txt which allows to download
the software packages of this site as well as those that you will
develop. It is enough to open it with a text editor ("
NotePad " on PC or " SimpleText " on MAC), to selec
everything, to copy and paste in the window "Terminal".USELESS from the version 2.01 of the ROM software
because instruction " TELECHARGEMENT" is integrated. Programs, written under files .txt, should
all have to possess a line situated in the beginning with the
instruction "TELECHARGEMENT". The same procedure will
allow their compilation.
download an autonomous application:
Your application must be at firs
finalized and possess an instruction of initialization to be necessarily
the last one of the program (in the last compiled file if there
are some of it). Software resident will execute automatically
this instruction as soon as the contents of the EEPROM will be
downloaded in the RAM after the power up of the card.
It is enough then to compile the file
eeprom.txt and to be allowed drive by the progress. The
recognized EEPROMS are 24C32 , 24C64 , 24C128, 24C256 and 24C512.
