Problems with attiny13a
OpAmp lowpass could be an option to next version, but not for this one :) Ripple voltage should not be more than 0.1V

Problems with attiny13a
Only load is input of opamp. Maybe I'll try to change bit smaller capacitor. EDIT: What do you suggest when I'm running PWM channel ~5kHZ? I don't need to generate any high...

Problems with attiny13a
Finally got it working by moving variables to global and fixed a calculation. Now the problem is that i'm using PWM for DAC and it isn't linear. Linearization with interpolation...

Problems with attiny13a
As you see, they are both implemented. PWM generation itself seems to be working as seems also frequency measurement. But conversion from frequency to PWM calculation fails for...

Problems with attiny13a
This version should work. It should measure frequency and convert it to PWM. BUT.. it doesn't work. Any ideas? #include #include #include #define HZ_LO 50 #define HZ_HI 150...

Problems with attiny13a
It seems to be problem with stack. When I simplify code (remove code and variables) it works. How can I change size of stack??

Hmm... What am I missing... I can't compile DualCDC or CDC demos: make: *** No rule to make target `DualCDC.elf', needed by `elf'. Stop. I can't see any error in makefile?

Uh.. AVR is acting little bit odd. :) I had another program which had input capture enabled and interrupt service routine for it and for overflow. In that application CDC serial...
