[avr-gcc-list] How to write Inline Assembly in WINAVR / AVR Studio

[Ramesh Arise]

Hi Sir.

        I am using stuff what ever you are sending  to improve my coding skills. while i am writing the coding i was strucked in Inline Assembly. I have to write the RRC, RLC (Rotate right with carry, Rotate Left With Carry) assembly instructions to Serial LCD programming . Could you please give me an idea how to write Inline assembly using WinAVR and AVR Studio or other options to write these instructions in C-Language. Waiting for your reply ASAP.


Thank you,

I was wondering if Atmel ever thought about making a multi-core AVR chip?
Specifically I am in the need of an array of simple processors, thus have
4-8 AVRon one chip would be great, basically they could run off the same
crystal and be connect through SPI or I2C internally. Then using the chained
JTAG they would be easy to program and such.



Of course I can design a board with several processors on it.

If Atmel ever considered doing such a thing, and I doubt that it has been
considered, it would take many months (or years) for it to be done. Very
likely you can't afford to wait that amount of time for your project.

That's probably your best bet.

Perhaps an alternative is to roll your own multi-core processor with an
FPGA and some of the many 8-bit processor cores running around. This has
the advantage of you being able to select different processors for
different purposes, and also to choose the internal bussing mechanism.
