Hi people,

By reading the following link (http://www.specs.de/~danni/to...index.htm), I've seen that it's easy to build a programmer for :
AT89C51 / AT89C52
AT89S8252 / A/89S53
AT89C1051 / AT89C2051 / AT89C4051
AVR: AT90S1200 / AT90S2313
AVR: AT90S2343 / ATTINY12
AVR: ATTINY15L

As sometimes small applications doesn't need a lot of resources, I'm interessted by these chips.
However, currently I'm working with the ISP 89c66x devices and this is very useful during the development phases to load and re-load the code to test.

My question is :
How to develop and debug with the AT and AVR chips (ex: at89c2051) with small budget.
For the moment, I'm only thinking to evaluate these chips so I won't buy any programmer or emulator.
Is there a simple emulator to build ? Or may it possible to include in the applicative software a code to load an hex file and write it into the flash.... As the embedded flash sizes are quite small, this code shouldn't be too large.

Any comment or suggestion would be appreciated.
