Re: simulavr support for new ATTinys

[Thomas K]

Hi Peter,

about new parts for simulavr: this is a longer story. To be able to 
debug you could choose a similar part with same or more flash and ram 
size. To be explicit: debug code! Maybe without simulation of interrupts 
or peripherals! Not all peripherals are simulated! Even in parts 
simulavr supports now.

If somebody has time and knowledge to implement the expected peripherals 
(or rewrite the allready existing for new parts!): you are welcome!

And now to attiny187: without datasheet I can't tell anything, what's 
possible to simulate or not. A quick search end in tne information, that 
attiny187 should have a new interrupt system. And that AVRStudio 7 
should support it. Datasheet? Nothing! Even in product matrix on 
microchip site no attiny187!

I have read on other boards about the information policy of microchip 
and the willingness of microchip to support open source and even 
avr-gcc. If they don't change it, you can assume that in a average time 
period the mega/tiny platform will be dead. If somebody in business 
would ask me, to choose mega or tiny controllers for future development, 
I would tell, that this would not make sense. It looks so, that the time 
of atmega/attiny is over. Even if this parts are really usefull in small 
requirements, where cpld is to small and inflexible and fpga is to much. 
Or also for prototypes and proof of concept. But this is maybe to less 
volume to be rentable.

cu, Thomas
