Is the STMPE610 the only Resistive Touch Controller that's compatible with CircuitPython?

Started a thread since there's already a convo going on

[covert leaf]

do you need a controller? We have this library: https://github.com/adafruit/Adafruit_CircuitPython_Touchscreen

Two questions:

1. Is this for resistive touch?
2. Does this work for any resistive touch driver?

Ignore question 1, just saw that it is for resistive touch

Still new to all this, it says "4 wire", I assume it should work for any that uses the same interface

that is the basic 4 wire touch, I though that was not even using a chip, it's just the basic resistive matrix

it does analog reads to measure the resistances

Wanted a chip for wake up optimization that a chip would provide

it looks like the STMPE610 is only resistive controller we support. You could wake up and poll the 4-wire every once in a while. In general I think we have mostly sold the 4-wire type

they are inexpensive and come with many screens

I see

Thank you!

there are some ideas for doing wakeup here: https://www.google.com/search?q=wakeup+resistive+touch+screen

without using a controller

[zealous topaz]

I see, I'll look into it

i don't remember the reason for your looking for another controller besides the STMPE610? Is it unavailable?

It is not that hard to write a new CircuitPython driver for an I2C device. You can often modify an existing one and just change some details.
