The AD9850 is a DDS Synthesizer chip sold by Analog Devices. Check the datasheet for general information about it.
This Rust crate implements an interface for embedded devices to control such an AD9850 chip.
- Reset the device
- Program in Serial mode
- Program in Parallel mode
- Power down / wakeup
This example uses the arduino-hal. The ad9850 library is not device specific though, so
it should be easy to adapt the example to other devices. The only requirement is that the device's pins have an implementation
of the OutputPin trait from embedded_hal.
#[arduino_hal::entry]
fn main() -> ! {
let dp = arduino_hal::Peripherals::take().unwrap();
let pins = arduino_hal::pins!(dp);
// Initialize the device
let ad9850 = ad9850::Ad9850::new(
pins.d4.into_output(), // Connect D4 (Arduino) to RESET (AD9850)
pins.d5.into_output(), // Connect D5 (Arduino) to DATA (AD9850)
pins.d6.into_output(), // Connect D6 (Arduino) to FQ_UD (AD9850)
pins.d7.into_output(), // Connect D7 (Arduino) to W_CLK (AD9850)
).into_serial_mode().unwrap();
// ^^^^ unwrap is ok here, since `set_low`/`set_high`
// are infallible in the arduino-hal.
// Set the output frequency to 1 MHz
ad9850.set_frequency(1000000.0);
