HEY !........

you do not need such a big ckt to prog DS89C ics.

they can be programmed using only 2 transistors. see the attached file (pdf). you can use hyper terminal for transferring hex file to these ics. software is also available for these purpose.
if you need i can upload the software too. it is also available on maxim website.

r u talking abt Dallas Semi Microcontroller Toolkit if so i have it

please give the details , how can i transfer hex through hyperterminal ?

[kelvar]

I think transfer in hyper terminal is using the send file option.

[chen]

prog with hyper terminal..

1. set the sw. to prog. mode

2. in windows accessories, click hyper terminal (for modem install choose no.)

3. type a name and select com port

4. pick 9600 baudrate, 8 bit data, no parity bit and 1 stop bit.

5. change the "flow control" to none.

6. press enter several times. the DS89C should respond with msg
     "DS89C4xx LOADER VERSION 1.0 COPYRIGHT (C) 2000 DALLAS SEMICONDUCTOR>"

7. Once you get prompt you can use the foll commands

     "L" (load), click "transfer -> send text file", select hex. wait until the loading is finished.
        scuccesful transfer is indicated by "GGGG>"

     "D" (dump) to see the contents of flash rom on the screen

     "K" (klean) will erase the entire contents of the flash

8. put the sw. in run mode and press reset.

and now your prog is being executed

hope it helps

Kova is right. where is rs232 connection
