Hello Everyone,

I have been playing around with the programmer and i love it to bits.
I like having the ability of adding devices and setting voltage requirements.

I want to add a chip with the use of an adapter. (2708)
Currently i have successfully created an adapter and read my chip perfectly. by selecting the device 2716 as they are very similar just buy adding the voltages separately.

But i want to be able to write to it aswell.
Is there away i can set the pulse of the 25v to suit the current chip.
I am guessing i am going to have to create a class file or can this be done in the devices.txt ?

If it can be done in the class file please let me know where these files are situated.

use WVPP="25V" to set the 25V VPP.

Yes however the 2708 and the 2716 use different pulse rates for programming.

2708 is like off the top of my heat 0.1 to 1ms
2716 was more like 50 - 100ms pulse rates.

So yes i can configure this to read just fine, by adding my additional voltages, but when it comes to writing if i cannot edit the class i am going to have to create a pulse circuit.

use speed to control the pulse width. Speed="5" should be a less than 1mS pulse.

fantastic!

That is just what i was looking for.

Where can i find a list off all these variables and a description of what they do?

Would be most helpful!

this way does not apply for many other chips. But I know if works on 27XXX series EPROMs.
