# Micropython-AD9833

This script is written in python 3.x for interfacing the AD9833 with micropython microcontrollers over SPI.

## Usage

Import

```python

from ad9833 import AD9833

from pyb import Pin

from pyb import SPI

```

Choose SS pin

```python

ss = Pin('X5', Pin.OUT_PP)

```

Choose SPI

```python

spi = SPI(1, SPI.MASTER, baudrate=9600, polarity=1, phase=0,firstbit=SPI.MSB)

```

Takes 2 arguments: sbi and ss

```python

wave = AD9833(spi,ss)

```

Set the frequency

```python

wave.set_freq(14500)

```

Set the wave type: 0 for sin 1 for square 2 for triangle

```python

wave.set_type(2)

```

Finally, send command to the AD9833

```python

wave.send()

```

You can also get some useful information

```python

print(wave.shape_type)

print(wave.freq)

```
