How can you be certain that you have successfully written to the EEPROM?

Do you have a programmer like the TOP 3000, which can read anything on the planet almost?

The problem with libs is that they need to throw in everything that's in the package in prog memory.

There might be 200 functions in them and you only make use of 3 of them.

What a waste of resources that is!

I mean, without relying on libs -- you should be able to do an Keypad-based engine immobilizer with under 500 bytes of program space.

Same goes for a Speed Limiter / Voltmeter (or similar) for your car.

I think that MikroElektronika have been fairly generous with their freely downloadable version which has the only restriction of being limited to 2KB of program space. Most professional programmers will never even come close to using 2KB, unless they starting using resourceful libs. There's a lot of...

I hate to point people away from the mE site but Microchip has a much more extensive USB library and resources that you may find helpful. http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=2651¶m=en534497 *laughing* Yeah and that's why it is quad times the price of this comp...

What are you planning on making a keystroke logger / dongle for software protection / ghost or something?

I have read articles on guys quite easily making their own USB joysticks that Windows automatically recognizes.

With a bit of hard yacka you'd figure it out ...

Hello Eng_Bandar

That's a very fast bauld rate that are you? running there.

9600 @ 8MHz -- no way mate.

You're dreaming ...

Hello Massimo You know, I personally always did find it much easier and much faster (in a sense of being able to read / write data) to a 256KB EEPROM as opposed to most other variants. Possibly due to the fact that the 24LC256 device has word sized addressing. In fact, I was only just able to pull o...

There is a working example for USB interfacing in MikroC's directory. I suggest that you read it thoroughly. I personally have little interest on the topic, so I am unable to offer you any further assistance off the top of my head. On top of that – I do not feel that you are being genuine. I do not ...

As for just USB interface to the PC ...

You won't be able to take it much further than controlling a few LEDs and reading voltages.

What in the bloody hell is the point of this?

You just wanna be the 1 million'th person to do it, is that it?

You're dreaming. You would need to know USB inside out and back to front for starters. You would need low-level programming skills at ASM level ... It is a tougher enough job figuring out the protocol of a 20 year old Nokia phone (ask Silicon Chip designer Peter Smith) -- let alone a USB-based, and ...

Not to say that it isn't possible of course ...

A guy spent 2 years working for MAME hacking into Capcom's CPS2 video game encryption

The last thing Apple want is some unauthorized person interfacing peripherals to their iPhone products.

Good luck!

My reasoning for saying this ...

If you could pull off such a project, then you wouldn't be on here asking for help with USB basics.

This your first electronics & software related project?

Have fun learning the iPhone protocol.

You're dreaming with your notions.
