TPA2016D2

Embedded-hal Driver for the TI TPA2016D2 Stereo Class-D amplifier.

Notes

• Max i2c clock 400 kHz

• Datasheet

  Example

  ```rust

  ![no_main]

![no_std]

use cortexmrt::entry; use cortexmsemihosting::hprintln; use panic_semihosting as _;

use nucleo_f401re as board; use board::hal::prelude::*; use board::hal::stm32; use board::hal::i2c::I2c;

use tpa2016d2::Tpa2016d2;

[entry]

fn main() -> ! { // The Stm32 peripherals let device = stm32::Peripherals::take().unwrap();

let rcc = device.RCC.constrain();
let clocks = rcc.cfgr.sysclk(84.mhz()).freeze();

let gpiob = device.GPIOB.split();
let scl = gpiob.pb8
    .into_alternate_af4()
    .internal_pull_up(true)
    .set_open_drain();

let sda = gpiob.pb9
    .into_alternate_af4()
    .internal_pull_up(true)
    .set_open_drain();

let i2c = I2c::i2c1(device.I2C1, (scl, sda), 200.khz(), clocks);

let mut tpa = Tpa2016d2::new(i2c);

// Print the registers
for i in 1..=7 {
    let v = tpa.read_device_reg(i).unwrap();
    hprintln!("{}: {}", i, v).unwrap();
}

// Set the gain
tpa.gain(32).unwrap();

// Should print 32
hprintln!("gain: {}", tpa.read_device_reg(5).unwrap()).unwrap();

loop {
}

} ```
