Most analog thumsticks are typically 10k range but the project I wanted to do expects 1Mohm range. The digital potentiometers I've looked at all uses I2C so is there a quick and easy interface from analog stick to digital potentiometers? Or should I use ATTiny84 for analog in, digital signal via I2C out? Wanting to use both analog stick on a donor PS2 controllers so I'd need 4x digital pots and at least 4 analog inputs (ATtiny85 has only 3 analog)
Or is there digital pots in 1Mohm range that doesn't use I2C and could work with something like ADC chip to skip the need for a microcpu?
