SPI Slave Select confusion
I haven't thought about that, for me it just seemed natural to keep everything succinct, when you're going to transmit then pull SS low and high when you're done. But indeed, you...

SPI Slave Select confusion
A problem you had in the first piece of code you copied directly from the datasheet was the "DDR_SPI", which is a placeholder name, it doesn't exist in the real hardware. But you...

Starting with AVR assembly

So thus far; An endless loop sooner or later in the program, just like we do when writing in C for the AVR. Gotcha.   Hm yes the simulator. I think I tried to use it but...

Haha okay, in my defense there are many levels of noobness

Thanks to both of you. Is a branch in the end of the program a must? What happens if the AVR reaches the last line of code and it's not a branch backwards? Is it the same as a "...

Thanks for the heads up. I guess that's my first line, yay! *edit, oh, seems it was unnecessary after all in AS6
