CC2650 Device Support Crate

Embedded Rust access API for TI CC2650 microcontrollers.

This crate provides an autogenerated API interacting with the CC2650 and its peripherals. The API is generated using svd2rust via dslite2svd.

Usage

To use, in your Cargo.toml:

[dependencies]
cc2650 = "0.1"

The rt feature is optional and brings in support for cortex-m-rt:

[dependencies]
cc2650 = { version = "0.1", features = ["rt"] }

Examples

See my blog post about creating this crate.

Note: The following example assumes you are using Rust 2018, I.e. Rust >= 1.31.

use cc2650;

fn init() {
    let device_peripherals = cc2650::Peripherals::take().unwrap();

    // Configure GPIO pins for output, maximum strength
    device_peripherals.IOC
        .iocfg10
        .modify(|_r, w| w.port_id().gpio().ie().clear_bit().iostr().max());
    device_peripherals.IOC
        .iocfg15
        .modify(|_r, w| w.port_id().gpio().ie().clear_bit().iostr().max());

    // Enable the PERIPH power domain and wait for it to be powered up
    device_peripherals.PRCM.pdctl0.modify(|_r, w| w.periph_on().set_bit());
    loop {
        if device_peripherals.PRCM.pdstat0.read().periph_on().bit_is_set() {
            break;
        }
    }

    // Enable the GPIO clock
    device_peripherals.PRCM.gpioclkgr.write(|w| w.clk_en().set_bit());

    // Load settings into CLKCTRL and wait for LOAD_DONE
    device_peripherals.PRCM.clkloadctl.modify(|_r, w| w.load().set_bit());
    loop {
        if device_peripherals.PRCM.clkloadctl.read().load_done().bit_is_set() {
            break;
        }
    }

    // Enable outputs
    device_peripherals.GPIO
        .doe31_0
        .modify(|_r, w| w.dio10().set_bit().dio15().set_bit());
}

Supported Devices

• CC2650 — Datasheet, Product Page

Note: There are other devices in the CC26x0 family that may also work but these have not been tested.

Generating
