Hi all,
I have decided to change my compiler from CV to winavr just because of limited size of my codes,but just started to write a simple program of blinking an led it gives me this error"opening dependency file
.dep/led.o.d No such file or directory "
Will you please help me on this?
This is my code:
#include <AVR/io.h>
#include <util/delay.h>
int main(void)
{
DDRD=0xff;
while (1)
{
PORTD=0x00;
_delay_ms(1000);
PORTD=0xff;
_delay_ms(1000);
}
}
I see some things not being right, but none that could explain this with the very limited information you have given.
There must be more warnings/errors there as this error merely gives note that something went wrong on another place and it had not created the file mentioned.
1 tip: define F-CPU before all the include files to make sure the delay functions use the right CPU clock frequency to calculate their delays on.
THIS is the total report:

js 
to winavr
I hope you know that is it very old and will not support newer chips. Any problems installing AS7 apart from the huge size?
It may be complaining about the upper case AVR?? Try lower case.

It may be complaining about the upper case AVR?? Try lower case.
But the point is that WinAVR2010 is actually a compiler from late 2009. That is 11 years ago. No one should be using WinAVR in 2020 really. The build tools have been much fixed and much extended in those intervening years. That dep/.d thing was a common fault back then (though a "make clean" should clear it).
If you want avr-gcc on Windows in 2020 then if there is some reason you don't want the whole of AS7 (editor, debugger, simulator, compilers, assemblers, linkers) you can get just the compiler/assembler/linker part separately as a "Toolchain" which is a kind of "modern day WinAVR". You get it here:
https://www.microchip.com/mplab/avr-support/avr-and-arm-toolchains-c-compilers
specifically: AVR 8-bit Toolchain v3.62 – Windows : https://www.microchip.com/mymicr...
I would, however, suggest that life is a whole lot simpler if you just download and install: https://www.microchip.com/mplab/avr-support/atmel-studio-7 (in which case forget "toolchain" as there's a copy in there already).

Absolutely!
And note that there's a whole load of Getting Started videos near the bottom of that page to, well - get you started!
Also a link to "Hands-On" training.

Thank you all,
I think I better try the [Atmel Studio] .
clawson AVRStudio4.18
Hello clawson
Yes, I still have an old WIN XP computer and there the AS4 is still active as it is on my WIN7 computer.
Now my question is - can I have AVRStudio4.18 AND AS7 on my WIN7 computer without interfering each other? And will my programmer still work when using AS7? It's a programmer with a 6-pin ISP header based on a Atmel AT90USB162 with 8MHz (STK500V2 protocol) which I use to flash my sw.
And what else (apart from AS7) do I need? Any additional sw (like Microsoft Visual Studio 2015 which I do not have) or is in the AS7 setup all neccessary sw included?
Thanks for your help 
regards

clawson js Just watch that you don't upgrade your programmer or debugger for AS7 or it will no longer work with AS4.
I have both on AS4 and AS7 my computer but have kept the JTAG Mk2 2 I have for AS4 and kept it away from AS7.

Just watch that you don't upgrade your programmer or debugger for AS7 or it will no longer work with AS4.
All you do is "update firmware" depending on teh version you are using. If you use your programmer on AS$, and then move to AS7, you update teh firmware in AS7 to make teh programmer AS7 compatible, and then when you go back to AS4 you update again to change teh firmware to AS4 compatible.
Annoying yes.
