# Build Instructions for Teensy 3.1
|
|
|
|
Currently the Teensy 3.1 port of Micro Python builds under Linux and not under Windows.
|
|
|
|
The tool chain required for the build can be found at <https://launchpad.net/gcc-arm-embedded>.
|
|
|
|
Downlaod the current Linux *.tar.bz2 file. Instructions regarding unpacking the file and moving it to the correct location
|
|
as well as adding the extracted folders to the enviroment variable can be found at
|
|
<http://eliaselectronics.com/stm32f4-tutorials/setting-up-the-stm32f4-arm-development-toolchain/>
|
|
|
|
In order to download the firmware image to the teensy, you'll need to use the
|
|
downloader included with TeensyDuino. The following assumes that you have
|
|
TeensyDuino installed and set the ARDUINO environment variable pointing to the
|
|
where Arduino with TeensyDuino is installed.
|
|
|
|
```bash
|
|
cd teensy
|
|
ARDUINO=~/arduino-1.0.5 make
|
|
```
|
|
|
|
To upload micropython to the Teensy 3.1.
|
|
|
|
Press the Program button on the Teensy 3.1
|
|
```bash
|
|
sudo ARDUINO=~/arduino-1.0.5/ make deploy
|
|
```
|
|
|
|
Currently, the Python prompt is through the USB serial interface, i.e.
|
|
|
|
```bash
|
|
minicom -D /dev/ttyACM0
|
|
```
|
|
|
|
## TIPS
|
|
|
|
### Install 49-teensy.rules into /etc/udev/rules.d
|
|
If you install the 49-teensy.rules file from http://www.pjrc.com/teensy/49-teensy.rules
|
|
into your ```/etc/udev/rules.d``` folder then you won't need to use sudo:
|
|
```bash
|
|
sudo cp ~/Downloads/49-teensy.rules /etc/udev/rules.d
|
|
sudo udevadm control --reload-rules
|
|
```
|
|
Unplug and replug the teensy board, and then you can use: ```ARDUINO=~/arduino-1.0.5/ make deploy```
|
|
|
|
### Create a GNUmakefile to hold your ARDUINO setting.
|
|
Create a file call GNUmakefile (note the lowercase m) in the teensy folder
|
|
with the following contents:
|
|
```make
|
|
$(info Executing GNUmakefile)
|
|
|
|
ARDUINO=${HOME}/arduino-1.0.5
|
|
$(info ARDUINO=${ARDUINO})
|
|
|
|
include Makefile
|
|
```
|
|
GNUmakefile is not checked into the source code control system, so it will
|
|
retain your settings when updating your source tree. You can also add
|
|
additional Makefile customizations this way.
