So, I wrote a simple program to blink an led in atmel studio.
Whenever I want to build the code. I receive an error message .
- recipe for target 'main.o' failed
- 'bit_is_clear' was not declared in this scope
- macro "bit_is_clear" requires 2 arguments, but only 1 given
'_delay&ms' was not declared in this scope
'else without a previous 'if'
- '_delay_ms' was not declared in this scope
Kindly check the picture to see this message.
Note am using AS 7.0

So you need to provide the macro bit_is_clear and also define your F_CPU speed and include the delay.h lib.
Just as the error msg says....

Please see Tip #1 for how to take a screenshot, and how to post it!
And how to do that as am still practically new to atmel studio
How do I do that @Jim
awneil I just wrote a tutorial on how to do replies in the forum: https://www.avrfreaks.net/forum/... - including how the forum shows what you're replying to.
And how to do that as am still practically new to atmel studio
There's not really anything special about Atmel Studio here - it's standard 'C' programming stuff.
There's a load of introductory videos to get you started with Atmel Studio on the Atmel Studio page:

awneil How to set Project Defines - such as F_CPU - in Atmel Studio:

Advantage of using the Project Defines over #defines in the source code:

Thank you for your response.
So, I uninstall the AS 7.0 as the VASSIST is grayed out and I installed AS6.0
writing the following code
#define F_CPU 8000000UL
#include <avr/io.h>
#include <util/delay.h>int main(void)
{
DDRB |= (1<<0);
DDRB &= ~ (1<<1);
PORTB |= (1<<1);
while(1)
{
PORTB ^= (1<<0);
if (bit_is_clear (PINB, 1))
_delay_ms(100);
}
else
{
_delay_ms(10);
//TODO:: Please write your application code
}
}
But I get the following errors
'else' without a previous 'if'
But I get the following errors
'else' without a previous 'if'
Thank you.
Issue sorted!
awneil I uninstall the AS 7.0 ... and I installed AS6.0
That's really not a good idea!
7 is definitely superior to 6.
The errors you are reporting are not due to installation problems.
Please see Tip #1 for how to properly post source code, and Tip #5 for how to mark a thread as solved.
As side from that.
I can't access the Vassist X feature of the atmel studio 7
awneil That's a separate issue - it wouldn't have helped with any of the errors reported above.
It would certainly be better to use AS7 instead of 6.
You could start a separate thread if you want help to get it working ...
Sorry I have been busy working at my day job, looks like Andy answered your questions.
Thanks Andy!
Jim
