STMPE1600 I/O Expander Rust Driver

This is a platform-agnostic Rust driver for the STMPE1600 I/O expander.

This driver can: - Setup the pins as input, output or interrupt pins. - Get/set the state of a specific pin. - Get/set the state of all the pins at once. - Enable interrupt capability. - Set the interrupt output polarity.

Interrupts

The STMPE1600 handles interrupts by triggering an interrupt output pin when it detects an interrupt on any of its configured interrupt pins. The polarity of the interrupt output pin can be configured to be HIGH or LOW, and when the interrupt is triggered, the microcontroller can get any pending interrupts by calling get_interrupts, which will also clear the pending interrupts on the STMPE1600 itself.

To-Do

• [X] Add interrupt polarity
• [X] Create a way to access each of the pins individually
• [ ] Implement embedded_hal InputPin and OutputPin traits
