Hi,

Good day!

Can someone help me with the 8 bit AVR.

Which binutils I can use for assembler compilation and linking?

I see that in Arduino they use - GNU assembler (WinAVR 20081205) 2.19

It looks that the project for WinAVR is here -
http://www.webring.org/l/rd?ring=avr;id=59;url=http%3A%2F%2Fwinavr.sourcefor ge.net%2F

But there is not much information about how to use the as.exe

Thank you and regards,

Daniel

Do you really plan to sell a device in such great quantities that it makes sense do invest a lot of software engineering effort in an 8 Bit arch instead of one of the (better) supported 32 Bit archs, just to save some cent per piece ?

Where did he say that he wants to sell anything? Maybe he just wants to try FPC on AVR 8-bit for fun?

Sven

OK :-) :-) :-)
(For me, this fun would be too expensive in terms of engineering effort.)

Have fun,

Why? I'd try it as well if I'd have the time. At least I could then help with improving/finishing the AVR port :)

And so would I, if I didn't have the i8086 port to work on ;-) Besides, it's the next logical step for the compiler to become 32/64/16/8-bit :)

Also, 6502 becomes even closer ;-)

The fact is that the 8bit AVR (Atmel) chips are well supported and more than just "some cent per piece" cheaper, and they work with a wider voltage range then any 32bit chip out there (without expensive circuitry to get the same voltage "agnostic"). They are the base, in form of the ATmega328(P) and ATmega32u4 MCUs, for the most common Arduino boards and their derivatives, the Arduino Uno and Arduino Leonardo. Very common, and very cheap... ;-)

And hence very useful when you want do do mass products.

But for any projects below 10.000 pieces to do I would try to take advantage of the benefits of modern 32 Bit archs E.g. very versatile PIC 32 chips (MIPS architecture) start @ $1.50 .
