ft6236

Platform-agnostic Rust driver for the FT6236, FT6206, and FT6236U capacitive touch screen controllers, built on top of embedded-hal traits.

Supported Devices

Chip	Chip ID
FT6206	0x06
FT6236	0x36
FT6236U	0x64

Features

• Multi-touch support (up to 2 simultaneous touch points)
• Touch event detection (press down, lift up, contact)
• Gesture recognition (swipe up/down/left/right, zoom in/out)
• Configurable touch detection threshold
• Hardware reset with proper timing sequence
• Optional defmt support for logging

Usage

Add the dependency to your Cargo.toml:

[dependencies]
ft6236 = "0.1"

To enable defmt logging:

[dependencies]
ft6236 = { version = "0.1", features = ["defmt"] }

Example

use ft6236::{FT6236, Config};

// Initialize the touch controller
let mut touch = FT6236::new(i2c);

// Reset the controller (optional, requires a reset pin)
touch.reset(&mut rst_pin, &mut delay).unwrap();

// Initialize with default config (threshold = 0x40)
touch.init(Config::default()).unwrap();

// Read touch points in your main loop
loop {
    if let Some(point) = touch.get_point0().unwrap() {
        // point.x, point.y - touch coordinates
        // point.event - PressDown, LiftUp, or Contact
    }

    if let Some(gesture) = touch.get_gesture().unwrap() {
        // Handle gesture (MoveUp, MoveDown, MoveLeft, MoveRight, ZoomIn, ZoomOut)
    }
}

Note

• INTn (interrupt output) is not managed by this driver. You need to configure the interrupt pin externally if you want interrupt-driven touch detection.
• The I2C default address is 0x38.

Minimum Supported Rust Version (MSRV)
