I'm happy to deal with my syntax and logic errors when they arise, so for now, I just want the thing to build as it is.Thanks for reading, and any help One question. this contact form
Like Rick said just put it in your include statement but you have to have the correct path! How do I convert text to datetime? Make loop more efficient Texas, USA speed ticket as a European citizen, already left the country What happens after reaching 99x items of a kind? Stop.I tried adding timerx8.c in the 'Other Files' section and got the three original errors again.It looks like the issue is with the makefile but I don't know enough about them

Build FAILED. ========== Build: 0 succeeded or up-to-date, 1 failed, 0 skipped ========== Log in or register to post comments Top JohanEkdahl Level: 10k+ Postman Joined: Wed. Maybe there is a way to compile your c code in the Arduino IDE, but I haven't figured out how unless I wrap your code in a c++ class. Rick February 08, 2012 by amartinez Rick. My targetx8.c is just a bunch of stub functions to give the linker something to be happy with.
This could be a moot point as perhaps to use the USART code I must use a c compiler. I'm really weak with Studio -- I haven't used it since like 2006. February 05, 2012 by Rick_S Don't add it to the avr directory, put it in your project folder or as PCBolt said, put the full path in your include statement. Thanks February 04, 2012 by Rick_S Why don't you just use the Nerdkit library?

We all have to use the one's that best fit us. http://www.atmel.com/webdoc/AVRLibcReferenceManual/FAQ_1faq_libm.html Studio really seems convinced that you're working in C++ rather than C, and that's what's forcing you to write in C++ rather than C. The path of least resistance, as @PhillyNJ found out, seems to be starting off in C++ for the Arduino libs, and then including whatever straight-C code wrapped in the "extern C" I am an advocate of your book, and I am compelled to inform you.
when in the Arduino IDE. weblink Also, I've added the path to the directory where timerx8.h AND timerx8.c sit, into the Libraries Search Path section of the AVR/GNU C Linker options, in the Project Properties. Well the error suggests that either the file that contains the function was not built/linked or that there's something in it (perhaps #if protection?) that prevents the body of the function Robert Keim Load More Your name or email address: Do you already have an account?
When you choose the project type, it knows how to compile the code. Here’s the code in question giving me the undefined reference error lcd_home(); fprintf_P(&lcd_stream, PSTR("Raw: %7.2f"), temp_avg); The header file “lcd.h” is called up but from the AVR Studio include files not I could go that route but that would not solve my existing problem. navigate here Yours has it in another subdirectory under the source.I don't think you need all the libraries you added (although I'm not sure AS isn't my bag).
I'm using AVR Studio 5.From what I know about C compiling, which is very little, the errors mean that it can't find the timerx8.c file. Crystal oscillator or silicon oscillator? The GCC compiler/linker will take care of the rest for you.
Done building target "CoreBuild" in project "GccApplication2.cproj" -- FAILED.

The important parts are below the all: targetI believe you can setup AS4 to use an external makefile, try this makefile (you'll probably have to modify it a bit to add but to no avail. If you must make a new project, see these instructions. -Paul paul 2011-05-08 17:26:21 UTC #5 By the way, I also noticed that in your modified program you were trying to You just gotta figure out how to convice it.
Shouldn't it be the case that AVR Studio populates the makefile itself from what you code and the options that you choose in the GUI?I'll put the makefile contents in the Target "CoreBuild" in file "C:\Program Files (x86)\Atmel\Atmel Studio 6.2\Vs\Compiler.targets" from project "C:\Users\Philip\Documents\Atmel Studio\6.2\AvrI2CTesting\TestOne\TestOne.cppproj" (target "Build" depends on it): Task "RunCompilerTask" Shell Utils Path C:\Program Files (x86)\Atmel\Atmel Studio 6.2\shellUtils C:\Program Files (x86)\Atmel\Atmel Did you pick these extensions? PCBolt, very informative info.
More precisely, you are not linking the files together. So I canged the Linker Flags section from## Linker flagsLDFLAGS = $(COMMON)LDFLAGS += -Wl,-Map=LED.mapto## Linker flagsLDFLAGS = $(COMMON)LDFLAGS += -Map=LED.map,-WIWhen I rebuilt the project I only had two errors. In Atmel Studio, it was a C/C++ project. The sample code provided in the book and this repo is for c only compilers (no C++ linkage) and does not compile in Atmel Studio (c++ projects) or the Arduino IDE
The other is in the /default directory. « Last Edit: January 29, 2012, 07:14:03 AM by ChrisMcC » Logged ChrisMcC Jr. PhillyNJ commented Jun 30, 2015 Hi - Thanks for the response. I think it's the makefile. The issue with the defines is due to Studio putting global defines somewhere other than the makefile.
Did you use a different extension from .c? That means I can relax abit and spend more time reading and learning, so I will be making use of the forums on both sites.Gertlex, that's what was confusing me. Then there was a long process of copying in other functions and variables in them that weren't recognised, until the program built successfully. However, when I try to compile it gives the following error: C:\Users\vincent\Documents\AVR\Contiki\default/../Contiki.c:145: undefined reference to `i2c_start_wait' Where i2c_start_wait is a function defined within the i2cmaster.h and .s files.
pulling my monkey hair out! So believe me, I'm no knocking it one bit. Jump to the solution. the command line.
