UART object now uses a stream-like interface: read, readall, readline, readinto, readchar, write, writechar. Timeouts are configured when the UART object is initialised, using timeout and timeout_char keyword args. The object includes optional read buffering, using interrupts. You can set the buffer size dynamically using read_buf_len keyword arg. A size of 0 disables buffering. |

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.
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
sudo ARDUINO=~/arduino-1.0.5/ make deploy
Currently, the Python prompt is through the USB serial interface, i.e.
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:
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:
$(info Executing GNUmakefile)
ARDUINO=${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.
