Conditional syntax for different MCU not working
Thank you all for the help. #if defined() was exactly what I needed. Here's the working code snippit: #if defined(__AVR_ATmega8__) //ATmega8 //INT0 register definitions #...

Need advice on keeping track of time
@JohanEkdahl: Nope, separate conversation with a person who went way out of their way to help... I didn't want to tread on his good will by asking him for even more help. @kk6gm:...

Broken avrdude on Linux
Yes! Thank you! This has been plaguing me for quite some time (well, since I installed 9.10, Karmic Koala). I've been booting into an older version of Ubuntu on a thumb drive to...

Is this an optimal way to use a timer?
I was unsure of the benefits/drawbacks of this situation. In my mind I thought that preloading the timer to trip at overflow would prevent any chance of missing a compare match....

Trying to understand why my Atmega168 doesn't respond.
What is the output of this: avrdude -c jtabmkii -p m168 -v If you're able to read the chip through ISP this should display fuse settings.

What protocol should I be using - LCD display
Thanks for the help. Unfortunately I don't have access to the A0 input so I must use 9-bit SPI. Thanks for pointing out the problems with my code. I wrote it quite a while ago...

What protocol should I be using - LCD display
The controller chip is an S1D15G14. I am using a 9-bit interface and have attached the timing diagram from the datasheet.

tiny2313: PD0 unable to sink when all PortD pins are low?
I decided on a 22 ohm resistor for the common anode. I plan to drive this from 3v unregulated (two AAA batteries) and always have at minimum 4 segments illuminated (the number 11...

tiny2313: PD0 unable to sink when all PortD pins are low?
Thank you. Yes I do understand the drawback to using a single resistor. This is not a production design and for my purposes I find the brightness when all segments are lit to be...
