# Programming the 640
|
|
|
|
## Python
|
|
|
|
### Introduction
|
|
|
|
The Python libraries for the 640 board and some example scripts are available via our GitHub repository. To install them open a terminal window on your Raspberry Pi (unless you are running with only the command line) and enter the following:
|
|
|
|
``` bash
|
|
$ git clone https://github.com/darkwaterfoundation/darkwater_python_640.git
|
|
```
|
|
|
|
### Example scripts
|
|
|
|
Now that you have downloaded the 640 libraries you should have a new directory called *darkwater_python_640, so let's move into that directory
|
|
|
|
``` bash
|
|
$ cd ./darkwater_python_640
|
|
```
|
|
|
|
If you list the files in this directory, you should see a few test scripts
|
|
|
|
``` bash
|
|
$ ls -al
|
|
```
|
|
|
|
**640motortest.py**
|
|
|
|
This script will start each motor port, in the forwards direction, in turn from left to right and then do the same backwards. To run the script enter the following:
|
|
|
|
``` bash
|
|
$ python 640motortest.py
|
|
```
|
|
|
|
**640servotest.py**
|
|
|
|
This script will move any servos connected to the servo headers left, then center, then right. To run the script enter the following:
|
|
|
|
``` bash
|
|
$ python 640servotest.py
|
|
```
|
|
|
|
**640steppertest.py**
|
|
|
|
This script divides the 6 motor ports into 3 stepper motor ports. Motor 1 and 2 will be stepper 1, motor 3 and 4 will be stepper 2 and motor 5 and 6 will be stepper 3.
|
|
|
|
Each stepper will be moved forwards and backwards through 200 steps when the test script is run:
|
|
|
|
``` bash
|
|
$ python 640steppertest.py
|
|
```
|
|
|
|
### Import libraries
|
|
|
|
Now you know everything works, it's time to write your own scripts. So create a new python script in your editor, within the *darkwater_python_640* directory with a memorable name and add the following lines to import our libraries:
|
|
|
|
``` python
|
|
import time
|
|
from darkwater_640.darkwater_640 import dw_Controller, dw_Motor
|
|
```
|
