New Studio 4 with WinAVR. Latest versions.
Simple test program will compile, but can't do a build all? Errors on *.elf ?
Have tried several new projects from scratch. Get the same results?
Is something set wrong? I don't know enough to fix this, especially don't want to make my own "make" file.
Thanks for any help!
Mike
I get one error, the description is below on Blinky.
Happens no matter what project I start, new or old?
avr-objcopy: 'Blinky.elf': No such file
4.19 does not find WinAVR so you must now set the location manually for each project under "Custom Options"
Thanks!
I un-checked AVR Tool Chain and tried a few times.
I see the option, but don't know what file to browse to? I want basic C. I tried a few and got error message that I had no compiler chosen?
Almost there? Don't know what file does the compiling?
Mike
Build failed... No build tools defined.
I have not picked the correct file yet?
Hit the "...config. options" button and go to "custom options" . Uncheck avr tools and in avr-gcc field you need to put the path to this, or wherever Winavr is on your PC :
C:\WinAVR-20100110\bin\avr-gcc.exe
In make field do :
C:\WinAVR-20100110\utils\bin\make.exe
OK!
Thanks! I wondered where the make file was!
Now I can continue!
Mike :D
I am getting the following error while building the code "undefined reference to main"
pls help me
I am getting the following error while building the code "undefined reference to main"
sr i am trying to compile a simple program of lcd interfacing using Avr studio 4 and winavr.......bt sr at the time of building it it shows an error that "AVR Simulator: Invalid opcode 0xffff at address 0x001c00
"sr what should i do now........plz help me
at the time of building
Anyway, flash that has not been filled with code usually holds 0xFFFF so if you end up executing 0xFFFF it means something went seriously wrong in your program and the PC ended up with a rubbish value. Just one of an infinite number of ways for this to happen might be something like:
void a_function(void) {
char buffer[10];
int i;
for (i = 0; i < 20; i++) {
buffer[i] = PINB;
}
}
That defines a 10 byte buffer on the stack but then writes to 20 locations. The ones "off the end" of the buffer are where the return address from which this function was called will be held so when this function does a RET it will go back to some completely random location.
As I say this is just one of an infinite number of ways to end up with PC holding an invalid value. You own the code, you have more idea why your own program is doing this than we do.
As your error clearly is not when building your thread hijack is completely off-topic for this question. I suggest you create a brand new thread in AVr Forum and post the code you are using because without it no one but you has any hope of seeing what it is you have done wrong.
sr my code is........
#include
#include
#define LCD_DATA PORTA // LCD data port
#define ctrl PORTB
#define en PB2 // enable signal
#define rw PB1 // read/write signal
#define rs PB0 // register select signal
void LCD_cmd(unsigned char cmd);
void init_LCD(void);
void LCD_write(unsigned char data);
int main()
{
DDRA=0xff; // making LCD_DATA port as output port
DDRB=0x07; // making signal as out put
init_LCD(); // initialization of LCD
_delay_ms(50); // delay of 50 milli seconds
LCD_write('A'); // call a function to write A on LCD
return 0;
}
void init_LCD(void)
{
LCD_cmd(0x38); // initialization of 16X2 LCD in 8bit mode

delay_ms(1);
return;
}
void LCD_cmd(unsigned char cmd)
{
LCD_DATA=cmd;
ctrl =(0<<rs)|(0<<rw)|(1<<en); // RS and RW as LOW and EN as HIGH
_delay_ms(1);
ctrl =(0<<rs)|(0<<rw)|(0<<en); // RS, RW , LOW and EN as LOW
_delay_ms(50);
return;
}
void LCD_write(unsigned char data)
{
LCD_DATA= data;
ctrl = (1<<rs)|(0<<rw)|(1<<en); // RW as LOW and RS, EN as HIGH
_delay_ms(1);
ctrl = (1<<rs)|(0<<rw)|(0<<en); // EN and RW as LOW and RS HIGH
_delay_ms(50); // delay to get things executed
return ;
}

Sr what should i do to remove this error........
Read this: http://www.nongnu.org/avr-libc/u...
sr still is a problem........bt its only a warning...and when i double click at it....a yellow colour's arrow points to my programs particular line that is "DDRA=0xff".....and the warning is

Dear sir my Code is.......

But sir as i build it.....it gives me a warning...

that is the reason it is not detecting myheader file.
What is interesting is that you were knowledgeable enough to change the optimization setting in the first place but not knowledgeable enough to read the warning and revert the optimization setting back to default :roll:

Sir, i recently downloaded avr studio 4.19 and have the latest winavr. I have already changed the pathways to winavr/bin/avr-gcc and winavr/utils/bin/make.
My code for a simple adc conversion using attiny 13a and the code is given above. The error i get while building is unrecognised command line option "mmcuattiny13a"
PS: im a newbie
Although it's 6 years old the C compiler in WinAVR does know the tiny13a:

So passing -mmcu=attiny13a should work. However your error message is "unrecognised command line option "mmcuattiny13a"" which suggests that a '-' at the start and a '=' in the middle are missing.
But seriously, why not upgrade to avr-gcc 4.8.1 or even 4.9.2? Atmel have builds of both for Windows.
