Still a few hiccups...
When I hit the reset button on the board I get a light sequence from the LEDs installed on the protoshield. Each flash quickly in turn so something seems to be working.
I went through the same sequence as before and now I get a red blink when uploading and some synch errors. I got some of the "nuisance" errors before but it doesn't seem to be working.
I was trying a different chip this time though and I had tried to do the bootload on it without success before and it doesn't seem to be working now either.
I may try loading a sketch onto the chip I had working earlier and see how it goes.
I did the usual continuity checks, etc. plus triple, triple checked the wiring and all seems OK. I have a sneaky feeling I'm forgetting to do something that I did right before but d@mned if I can figure out what it is
Seems like I used the sketch from post 39 :
http://arduino.cc/forum/index.php/topic,108797.30.html
Strange, I went back to the breadboard with my original setup and I can't duplicate earlier success... I'm getting the "avrdude PAGEL BS2" and "protocol error" errors after burn bootloader and uploading the blink sketch which I believe are just nuisance errors but no blink...
One thing I'm not sure about is if the capacitor is needed for "burn bootloader"? And will it damage the chip if I burn it more than once. Earlier I managed to load several different sketches onto the 85 without any problems but after putting this shield together things are a little wonky...
I suppose I need to troubleshoot the pins on the arduino which are used to program the 85. I may have damaged them. I figure if I can get pins 11, 12 and 13 to blink an LED then all is well on that front.
Thanks again for all the help. It's just a little frustrating that I can't get it to work again...
Well, the pins seem to be working. I can still blink LEDs on 11, 12 and 13.
Triple checked the wiring again:
Pin 10 on Arduino to pin 1 on 85
All is well again... Looks like my oscillator or something is screwy because it blinks every 7 seconds or so. I'm pretty sure I loaded 8mhz but I was pretty sure I had it wired correctly too...
