EEPROM

Where do I start!!!! A found a JDM programmer on Ebay for 10 bucks, is this a good starting programmer? Also, can you upload a schematics to IC-Prog or is it all code, and if it is, is it easy to learn? :?

Thanks

What exactly do you want to do ?

 

[edisonboy]

This is it, is there any software out there that I can draw a schematic in and have it translate it to code to program into an EEPROM? :?:

I think you misunderstand what EEPROMS do. All EEPROMS do is store a list of 8 bit binary values. Thats it.

I think what you're interested in is a microcontroller. a microcontroller is a tiny computer in a single IC chip. You can program a microcontroller with "code". The code you're talking about is a list of instruction for the microcontroller to do. If you're interested in learning how to do this your best bet is to go buy a book about microcontrollers and read up a little before you buy any hardware.

What can you do with the 8 bit binary values? (example?)

Store information.

For example, in modern television sets, a EEPROM is used to store the channels, startup values for sound, color, ...
By using EEPROM these values are retained even when the set is unplugged.

What is a 555 timer then? Is it eeprom or a micro-controller? Is it possible (if so, what do I need) to take a small circuit and burn it on to a micro-controller and just have a power in and a power out.

A 555 is a dedicated chip, just a collection of transistors and resistors joined together in a particular way - it has no programmable capabilities at all.

Taking a circuit, and blowing it into a chip isn't really possible, depending what you require the circuit to do you may be able to program a micro-controller to do the same job - but it's likely to require extra hardware for many purposes.

You could program one to work in a similar way to a 555, as a monostable or astable - in fact it would work far better and more accurately, but it wouldn't be a pin for pin replacement, you would need to program it for each individual job.
