2020年01月03日 | codeblocks+winavr开发avr单片机（atmega16）
2020-01-03 来源：eefocus
在avrfeaks论坛里，有一个帖子是关于在codeblocks环境下（与winavr结合）开发avr单片机的，挺不错的，这里转载一下：
I got curious, so I downloaded the current C::B installer. It looks better than when I last used it (a year ago?):
- A working installation program, with no need to install graphics packages and stuff (WxWidget, MinGW) separately.
- A user manual is now available.
Upon first launch I was asked if C::B should "steal" the C and C++ filetypes. I said no at this moment.
I then was presented with a choice of copiler, and THERE IT WAS: GNU AVR GCC Compiler
So I chose that, and started creating a new project. The project type "AVR Project" was available so I chose that.
A wizard starts with the usual stuff in the first step: Project name, location etc.
Second step: Select AVR processor, and I have a ATmega88 on the STK500 so I chose that. Here is also the setting of F_CPU, what files to generate and an option to run avr-size after build.
Finish!
I now have a main.c, with a int main(void) which I add two lines to so I get:
Code:
#include int main(void) { DDRB = 0xFF; PORTB = 0x55; while(1); return 0; } Quote: Compiling: main.c Quote: "CBAVRtest - Debug" uses an invalid compiler. Skipping...
I hit build and ... it does not work. C::B can not locate the compiler, and used odd names (In my view) for it. ON to theSettingsmenu,Compiler and Linker... item, Toolchain Executablestab. There I browse for the correct executables (in my case they are in the WinAVR installation) and add paths to the two directories containing those executables.
But there it stops: I cannot get a build to build correctly.
Choosing Compile current file I get
cc1.exe: error: missing argument to "-mmcu="
Process terminated with status 1 (0 minutes, 0 seconds)
0 errors, 0 warnings
A double-check that the AVR model is set in the project confirms that it is.
Choosing Build it gets worse:
Nothing to be done.
Oh, well... It was woth the half-hour I spent. C::B has a nice forum with helpful people (you have to do your home/leg-work though. If you think we here at AVRfreaks are tough then you've seen nothing. Them there C::B'ers are far worse (or better?
)
If anyone does anything more on this I am very interested in the results! Come back here with them!
