dac8564
A platform agnostic library for the Texas Instruments DAC8564.
description
The DAC8564 is a low-power, voltage-output, four-channel, 16-bit digital-to-analog converter (DAC). The device includes a 2.5V, 2ppm/°C internal, reference (enabled by default), giving a full-scale output voltage range of 2.5V. The internal reference has an initial accuracy of 0.004% and can source up to 20mA at the VREFH/VREFOUT pin. The device is monotonic, provides very good linearity, and minimizes undesired code-to-code transient voltages (glitch). The DAC8564 uses a versatile 3-wire serial interface that operates at clock rates up to 50MHz. The interface is compatible with standard SPI™, QSPI™, Microwire™, and digital signal processor (DSP) interfaces.
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: Example based on the stm32h7xx-hal
.
fn main() -> ! {
// SPI interface pins
let sck = sck.into_alternate_af5();
let mosi = mosi.into_alternate_af5();
// Control lines
let ldac = ldac.into_push_pull_output();
let enable = enable.into_push_pull_output();
let nss = nss.into_push_pull_output();
// Initialize SPI
let spi: Spi<SPI2, Enabled> = interface.spi(
(sck, NoMiso, mosi),
spi::MODE_0,
20.mhz(),
prec,
clocks,
);
// Initialize the struct
let mut dac = dac8564::Dac::new(spi, nss, ldac, enable);
// Enable the DAC8564
dac.enable();
// Blocking call. Set value to 1000 on the DAC
dac.write(Channel::A, 1000).unwrap();
}
contributing
I am not actively using the DAC8564
chip in any of my current prototypes. For this reason development, features and bug fixes could be slow, but I am fully open to any contribution. Please create a PR if you have any changes 🙏🏼
