Hi everyone,
I've just received few ATTINY 10 and several LM 327 in small package. The size of a SMD resistor !!!
So, my plan is to use them to make the smallest PI detector, just for the challenge and for fun.
I programm using ATMEL STUDIO 7. T My programming skills are not so good but it's the occasion to upgrade them.
The ATTINY has 4 I/O pins that can be used as PWM, CAN, I/O and interrupts.
I don't know wher to start but i'm awared of the PI functionning.
I'll used a PWM output to drive a MOSFET directly (IRL's mosfet can be drived without transistors).
This signal will drive an interrupt input in order to launch a measurement.
Those measurements will be put in a FIFO array in order to compare a mean signal level with three sensitivity levels.
One input will be connected to a swith with pullups and two pushs duration :
Long push : Zeroize the sensitivity with the actual field value
Short push : toggle sensitivity levels that will be added to the compare value.
I'de like to have your advices and hints for finalize and calculate the OP AMP values...
