NOTES FOR REPL (READ EVAL PRINT LOOP)

- Easiest way to test code and run commands on the pyboard

- Can be used in addition to the main.py script

- Need to be connected to pyboard's USB serial (instructions below)

-----------------------------

Mac OS X

1. Open Terminal

2. Type in the following and hit enter:

screen /dev/tty.usbmodem*

-----------------------------

Windows:

1. Make sure the pyboard driver('pybcdc.inf' which is visible in the same directory as 'main.py' and 'boot.py') is installed.

2. Access the Device Manager (Start > Control Panel > Device Manager) and click on 'Ports' to check the port to which the pyboard is connected (eg. COM8).

3. Install PuTTY < http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html >

4. Run putty.exe

5. In the PuTTY Configuration window, click on 'Session' on the left pane.

6. Under 'Connection type', select 'Serial'

7. Change the 'Serial line' field to the port on which your pyboard is connected (eg. COM8)

8. Change 'Speed' to 115200

9. Click Open

-----------------------------

Linux:

1. Open any terminal

2. Type in the following and hit enter:

screen /dev/ttyACM0

3. You may have to replace ACM0 with ACM1 or a higher number and may have to prefix sudo to the command

-----------------------------

Now that the serial program is running hit enter and the prompt i.e. >>> will appear

Type in the following and hit enter:

pyb.LED.toggle(4)

The blue led on the board should toggle its state (if on, goes off and vice versa)

On most terminals the upward arrow key is a shortcut to go to the last used command. Hit it and pyb.LED.toggle(4) should re-appear. If not just type it out. Hit enter.

The state of the blue LED on the pyboard (LED 4) toggles its state each time the command is called.

FOOTNOTE: added a boot.py that imports pyb and an empty main.py

If pyb is not imported it will obviously need to be imported while playing with REPL.
