Are bitwise operations unsafe?
Thank you, another thing I learn ;)

Adc and pin configuration help
mmm I see there are internal overriding signals. Am I right thinking that enabling ADC, will turn all ADC pins into analog inputs? And the digital input register is there to...

Looking for a NPN transistor
I used a resistor on emitter (emitter polarization), that's why the transistor didn't blow up. But still got very hot. So tried Geronimo's suggestion and it's working great now...

Looking for a NPN transistor
lol, I've seen the schematic on a university book. And there was no base resistor in it. But i'll research a bit more on this topic and digital output currents. Thanks for the tip...

Looking for a NPN transistor
Hi guys, I'll be having a 430mA Ic current. Vcc will be 10V and Vb will be digital output. I'm not using a resistor in the base, is it wrong? So, Ve will be 5-0.7 = 4.3V There is...

Penalty for using 32bit variables?
It's already solved guys, thanks! Hosted my code on github: https://github.com/jvalencia80/atmega-timers take a look :) (I forgot to add UL on some constants of the readme, but i'...

Penalty for using 32bit variables?
hi, i'm using avr-gcc on linux, latest stable I think I will be using uint32_t for counting and some divisions. Nothing complicated.

ok, i'll check it. thanks guys

Register names in several chips
lol, ok, so it's impossible to code for all mcu's, but what are the most used families?

Port output speed
I mean input/output and latches. For input, there is a timing diagram in the pdf, but nothing for outputs. So I supposed, output is atomic?!
