programming avrs

Feb 082010

I have been working on avr project for almost a year now. As I have been getitng closer to completion I have finally jumped from arduino to my own custom avr board. Then came the problem of programming the icsp. I tried 2 different serial and parallel programmers to no luck. And then I thought why not use an arduino to programmer to program my avr 168p. I tried 4 different software ones to no luck and then found this mega-isp . works great, I was able to flash my avr with no troubles I highly recommend it.

I seemed to have a lot of trouble getting pwm code going. below is some simple code that got me going. looking back on it now I am unsure as to why I was having such problems. I think its because, arduino, port codes, and timer codes, and pwm codes dont exactly match and I wasnt looking at the reference material. anyways hope this helps.


int main (void)
{
        DDRD |= (1<while (1)
        {
                asm("nop");
        }
}

I decided having it post to my blog wasnt just enough. Why not track myself via google constantly. below is the bash script i have running in cron minutely to record my coordinates. Enjoy.

if [ `ls .|wc -l` -eq 0 ]; then
    wget -q "http://www.google.com/latitude/apps/badge/api?user=${ID}&amp;type=json" -O new
    mv new `date +%s`
else
    File=`ls |tail -n1`
    Last_Time_Stamp=`grep timeStamp $File|cut -f2 -d':'|cut -f1 -d','`
    wget -q "http://www.google.com/latitude/apps/badge/api?user=${ID}&amp;type=json" -O new
    if grep -q $Last_Time_Stamp new ; then
        rm new
    else
        mv new `date +%s`
    fi
