well yes, try again, and again.. beleive me, it's worth the hard work! may it not work this<br />
time, leave a message here with your observations, and i'll help you to get it working.<br />
Thanks very much,I operated the circuit by your circuit diagram,then connected it to PC,and<br />
programed with a light flash program,I found the S51 was programed correctly,and worked<br />
well.my english is poor,^_^Thanks again.<br />

Sawasdee Krub,I am a newer in MCU and <strong>ISP</strong> field from Thailand. I am applying your <strong>ISP</strong>programming<br />
software and schematic. But still can not write the code on 'AT89S8253(TQFP)'.<br />
I have simple questions as following.1.When pluged the Parellel Port to a computer and 5Vadaptor<br />
not yet supply, the indicator LED is lighted. Is it right?2.Can I supply voltage 'Vcc-5V'<br />
directly to the Reset pin-4 without a seriated Cap-1uF(Because of the <strong>In</strong>ternal Power-On Reset<br />
feature).3.My X’tal is 20MHz,Does this <strong>ISP</strong> Programmer control SCK-signal frequency properly<br />
according to the MAX-1/16-Crystal Frequency and there is dynamic baud-rate depending X’tal-<br />
Frequency come along with this?4.I press 'Restart' button and next 'Read Signature', when<br />
starting programming the MCU, <strong>for</strong> recognition,Is it right?(Would you please give me the brief<br />
procedure of manual?)5.The <strong>ISP</strong> programmer reported 'NOT KNOWN(FF,FF,FF)' when finished<br />
pressing 'Read Signature' Button ,and when change the new one of MCU and recheck wiring of<br />
the schematic, this problem is persisted.Thank you <strong>for</strong> your sharing and I will do this when I<br />
know these enough. It is the good thing.Sorry <strong>for</strong> not skill in English.Charin.E<br />
Yes this is abolutely normal, same thing happends to me...<br />

It's better to keep the Capacitor connected, specially with long cables. (i tried to remove the<br />
cap, and some of the programmers didn't work.<br />

I usually puc the frequency to MAXIMUM and let the software hande it. but when working with<br />
long cables, lowering down the frequency can make it safer...<br />

Well, here again, what i usually do it to hit the "Erase and program all" button. that's all.<br />

Let us know how it went... good luck<br />

How come you get your led bright without power?<br />

Because the parallel port of the computer can provide some power through it's I/O pins...<br />
some people even use that to power their circuits.. but i'ld say it's not good engineering...<br />

I am able to read hex file from 89s52 chip but can't erase or write the chip, even though i<br />
have tried it on three device but still i can't gate success. so, please help me.<br />
