Pause/Pulse + Pulse/Pause PWM?
Is it possible to set a pause/pulse to a pulse/pause PWM period, so the middle will be a pulse which can be adjusted from two directions, so more resolution. So were the pulse of...

No AVR with 16 bit fast PWM and PLL?
I wonder which AVR has a 16 bit timer with fast PWM and a PLL at 64MHz. I need 12bit PWM @ 15kHz.

How change the duty cycle of a sine?
I wonder how to change the duty cycle of a sine. Sine is always 50-50, how can I change this? I have a sinetable with for example 256 samples. Looks like I cannot use the...

Drawing lines on an LCD
I can plot pixels on an 128x64 LCD (controlled with an ATmega8), but how can I draw a line? For example I want a line from 0,0 to 63,7. How can I calculate the points (pixels) in...

[ASM] can this be done differently?
It's not the perfect way? notLow: cpi Y, 8 breq loEight brlo loEight ;if Y > 8, subi Y, 8 ; -> Y - 8 rjmp notLow loEight: Is there a shorter and better way to do this?

How from number to bitnumber? (ASM)
How can I set a bit corresponding to the number in a register? (numbers 0 to 7) For example. 00000101 -> 00100000 (five -> 5th bit)

timer1 ovf, LED off, @ ADC a glitch
I am free running the ADC (tiny26), and start timer1 @ ck/16384 when the ADCvalue reads 120 (means ovf after 0.524 sec ,AVR running @ 8MHz RC clock), and when a timer1 ovf occurs...

RC=8MHz, ADCclock 4MHz, t=3.25usec?
Is this correct. An ATtiny26 running @ 8MHz internal oscillator, ADCclock = 4MHz (clk/2) Does this mean one conversion takes 3.25 usec? (13ck/4MHz)

AVR @ 32.768kHz & ADC @ full speed
If I run an AVR @ 32.768kHz, will the ADC speed also decreases? System clock down is ADC clock down? How can I run the AVR @ 32.768kHz and the ADC at full speed? Thanks.
