Minimum mA sleep and chicken and egg
Quote:which monitors the INT0, pin for a key press. Yes, that is the chicken and egg there, to get a signal on int0 I have to have the op amp powered but Ahhh... I think with all...

Peak Amplitude Detector
I dont have the part numbers at hand but I am using a piezo buzzer and a single supply dual op amp to feed the comparator on a tiny13 This gives me trigger on off but no amplitude...

Pot or Not?
Yes with the calibration and micky mouseing around I decided to get some increment-decrement digital pots with 100 steps, I can use a high low transition on one io pin to...

Pot or Not?
I am using a single supplu op amp so no neg suppply is needed Also I am using 4.5 volts for both the avr and the op amp (op amp runs at 3V to 18V I am ging to try the pwm method...

How to Read VCC without external circuit Tiny45V
I don't use bandgap at all (that Iknow of anyway) all I did was set the reference voltage to VCC instead of the 1.1 or 2.56 ref voltages. (the reference to VCC is internal to the...

How to Read VCC without external circuit Tiny45V
Quote:or.. is there another way I should be thinking of to calibrate the gauge to the voltage supply? Yes there is metron. Just use the VCC as a reference voltage for the ADC,...

Assembler vs C
Really it boils down to the task at hand and the space you have to work with. I like the Bascom compiler for mega48's and program design as you can use both where needed. I use...

[DIS] [HARD] Using the analog comparator...
Just set your positive input at 1/2 what the mic is using and use the interrupt perhaps debounce as you would a switch. You don't need the bandgap as the mic will be at 0V no...

I looked around.. I'm a bit lost (newb)
I started with the basic stamp folks at parallax (well C-64 20 years ago) but for getting started programming chips and tons of stuff to read on small circuits and connecting them...

RCALL vs SRAM in tiny12
Finally one I can answer. Page 8 in the datasheet During interrupts and subroutine calls, the return address program counter (PC) is stored on the stack. The stack is a 3-level-...
