do a little bit of subtraction
and then output the values
I've looked at the attiny, but that appears to just have the SPI interface
Quoteand then output the valuesWhat sort of values? Floating-point? Discrete? Randomly generated?
QuoteI've looked at the attiny, but that appears to just have the SPI interfaceThe ATtiny2313 (and family) has a UART.
I'm getting pulse lengths to read a RC receiver I had lying around.
QuoteI'm getting pulse lengths to read a RC receiver I had lying around.What is the price if a pulse is missed?In your post you mention "cheap" and "four digital inputs". Why not just use four pins on your Arduino and use pulseIn to read the pulses?
Using the Arduino is too slow
I probably did something wrong though,
I found something that might work
QuoteUsing the Arduino is too slowThe Arduino is just an AVR like most others. If you can do it with a tiny13 you can certainly do it with a mega328.
