dac8564

A platform agnostic library for the Texas Instruments DAC8564.

• https://crates.io/crates/dac8564

Add the package with Cargo: dac8564 = "0.0.1"

features

• Also supports the Texas Instruments DAC7565, DAC7564, DAC8164
• Full no-std support
• Implemented with embedded-hal (https://docs.rs/embedded-hal/0.2.3/embedded_hal)
• Blocking and non-blocking support

example

Note: Quick example based on the stm32h7xx-hal.

blocking

``` fn main() -> ! { // SPI interface pins let sck = sck.intoalternateaf5(); let mosi = mosi.intoalternateaf5();

// Control lines
let ldac = ldac.into_push_pull_output();
let enable = enable.into_push_pull_output();
let nss = nss.into_push_pull_output();

let spi: Spi<SPI2, Enabled> = interface.spi(
    (sck, NoMiso, mosi),
    spi::MODE_0,
    20.mhz(),
    prec,
    clocks,
);

let mut dac = dac8564::Dac::new(nss, ldac, enable);
dac.enable();

// Blocking call. Set value to 1000 on the DAC
dac.write_blocking(&spi, Channel::A, 1000);

}

```

non-blocking

``` fn main() -> ! { let mut dac = dac8564::Dac::new(nss, ldac, enable); dac.enable();

// Prepare the transfer, the payload value here is the data that needs to be
// written to some kind of buffer, e.g. for DMA or Interrupt usage.
dac.prepare_transfer(Channel::A, 1000, |payload| {
    // Write payload values to a DMA buffer
});

} ```
