I agree. One should be prepared to face a flaming war on this list, but I
think that a substantial improvement is worth to endure this.
Hi everyone,
I am a new member of this list. I have just started using AVRs and have been
developing on a mega32 for a few months.
My question is on memory access for string operations. I realise that the two
different memories have different methods of accessing, escpically for string

Thanks a lot for all your advices. I finially have

1. The baud rate calculation should be based on
3.686Mhz (default fosc for STK500).
2. Fuse change, I select next option

I can increment the second's second variable up to 9. But, how can i
display numbers greater than 9, i.e, 10, 11,... by changing both
second's first and second's second varaible at the same time?
Can't you increment the seconds from 9 to 10?
If not, can you detect when the

Great!
How about the following API:

But only these. ;-)
For C programs, they'd yield a compile-time error

Only using C++, and virtual base classes -- which naturally will
