Crate gt9x 

GT9x Touch Screen Controller Driver

This crate provides a no_std driver for the GT9x series of capacitive touch screen controllers. It supports both asynchronous and blocking I2C communication.

Supported Chips

• GT911 (5 points)
• GT928 (10 points)
• GT9147 (5 points)

Features

• async: Enables the asynchronous driver based on embedded-hal-async. This is a default feature.
• blocking: Enables the blocking driver based on embedded-hal.
• defmt: Enables logging with defmt.

Usage

Asynchronous Driver

use gt9x::{Gt911, Gt9x};

// let i2c: I2c = ...;
// let mut int_pin: Wait = ...;
// let mut buf = [0u8; 64];

// Without interrupt pin
// let mut gt9x = Gt9x::<Gt911, _, _, _>::new(i2c, &mut buf);

// With interrupt pin
// let mut gt9x_int = Gt9x::<Gt911, _, _, _>::new_int(i2c, &mut buf, int_pin);

Blocking Driver

use gt9x::{Gt911, Gt9xBlocking};

// let i2c: I2c = ...;
// let mut buf = [0u8; 64];

// let mut gt9x = Gt9xBlocking::<Gt911, _>::new(i2c, &mut buf);
