Waterproof a rotary encoder
I've got a small Sharp mechanical rotary encoder with 24 detent positions (11) and I want to know how I can make it waterproof. CW = 11 10 00 01 11 CCW = 11 01 00 10 11 What I do...

PWM 2313
Gday I setup the PWM function on a AT90S2313, output at PB3 (OC1) Xtal is 4MHz. Timer1 running @ ck/64, PWM OC1 clear and 8-bit mode, but a measure a PWM period of about 8msec on...

PWM, servo and jitter
What is the problem with jitter and PWM? How can I filter a normal i/o, so that I have no more jitter? I need 12 PWM signals, I can take 12 tiny's or 2 mega128's, then I have real...

Saving registers using double
8) I am using a lot of registers (almost all lower, one left), so now I use doubles. Program size increases a littlebit. How can I do the next piece of code shorter...

Interrupt at pinswitch problem
Here I am again... :oops: I have a circuit with LED's, and when an timer1 interrupt occurs sometimes I see the LED's switch on and off very fast. Now I use cli to disable the...

No tiny AVR with 16bit timer and ADC?
Which AVR (tiny) has a 16bit timer and ADC and goes up to 20MHz clock? Seems none? Only ATmega48/88. Before there was an all AVR table on this website with all the features with...

How calculate T from f?
I want to calculate T=1/f. But how can I devide 1/f? This will be very small numbers when f gets greater. Difficult? :roll:

What is the lowest PWM freq. possible?
I wonder what is the lowest PWM frequency possible for an AVR? Highest is 500kHz fast PWM, but is there also a slow PWM function (trick)? :roll:

Using multiple ADC channels
How does multiple ADC channels work? I understand does you have to run the ADC in free running mode, and wait until conversion complete interrupt occurs, then switch the ADMUX? Is...

0 - 1023 from 1023 - 0
8) I have a 10k pot hooked to an ADC input (ATtiny26), but the turn direction is wrong, now going from 1023 to 0 when I turn right, I want it going from 0 - 1023 when turning...
