Caring for your pyboard ----------------------- Because the pyboard does not have a housing it needs a bit of care: - Be gentle when plugging/unplugging the USB cable. Whilst the USB connector is soldered through the board and is relatively strong, if it breaks off it can be very difficult to fix. - Static electricity can shock the components on the pyboard and destroy them. If you experience a lot of static electricity in your area (eg dry and cold climates), take extra care not to shock the pyboard. If your pyboard came in a black plastic box, then this box is the best way to store and carry the pyboard as it is an anti-static box (it is made of a conductive plastic, with conductive foam inside). As long as you take care of the hardware, you should be okay. It's almost impossible to break the software on the pyboard, so feel free to play around with writing code as much as you like. If the filesystem gets corrupt, see below on how to reset it. In the worst case you might need to reflash the MicroPython software, but that can be done over USB. Layout of the pyboard --------------------- The micro USB connector is on the top right, the micro SD card slot on the top left of the board. There are 4 LEDs between the SD slot and USB connector. The colours are: red on the bottom, then green, orange, and blue on the top. There are 2 switches: the right one is the reset switch, the left is the user switch. Plugging in and powering on --------------------------- The pyboard can be powered via USB. Connect it to your PC via a micro USB cable. There is only one way that the cable will fit. Once connected, the green LED on the board should flash quickly. Powering by an external power source ------------------------------------ The pyboard can be powered by a battery or other external power source. **Be sure to connect the positive lead of the power supply to VIN, and ground to GND. There is no polarity protection on the pyboard so you must be careful when connecting anything to VIN.** **The input voltage must be between 3.6V and 10V.** @ 1.1.1.1 log @Import micropython version 1.5.2 into othersrc. Micropython is a python3 implementation that has been optimised for micro-controllers and small embedded systems. It also has a "unix" port. It has an MIT license. This is version 1.5.2 of micropython. MicroPython implements the entire Python 3.4 syntax (including exceptions, "with", "yield from", etc.). The following core datatypes are provided: str (including basic Unicode support), bytes, bytearray, tuple, list, dict, set, frozenset, array.array, collections.namedtuple, classes and instances. Builtin modules include sys, time, and struct. Note that only subset of Python 3.4 functionality implemented for the data types and modules. This is the standard micropython source (version v1.5.2), which has been adapted to use reachover infrastructure. At the present time, libffi (from pkgsrc) is used. Alternative locations for libffi can be set using the PKGSRC_PREFIX definition to make. In the whole scheme of things, micropython is quite small: % size bin/micropython text data bss dec hex filename 393495 1624 2208 397327 6100f bin/micropython % and runs much as expected: % bin/micropython MicroPython v1.5.2 on 2016-01-13; linux version Use Ctrl-D to exit, Ctrl-E for paste mode >>> print("hello world") hello world >>> list(5 * x + y for x in range(10) for y in [4, 2, 1]) [4, 2, 1, 9, 7, 6, 14, 12, 11, 19, 17, 16, 24, 22, 21, 29, 27, 26, 34, 32, 31, 39, 37, 36, 44, 42, 41, 49, 47, 46] >>> % python2.7 Python 2.7.10 (default, Oct 17 2015, 17:55:29) [GCC 4.8.5] on netbsd7 Type "help", "copyright", "credits" or "license" for more information. >>> print("hello world") hello world >>> list(5 * x + y for x in range(10) for y in [4, 2, 1]) [4, 2, 1, 9, 7, 6, 14, 12, 11, 19, 17, 16, 24, 22, 21, 29, 27, 26, 34, 32, 31, 39, 37, 36, 44, 42, 41, 49, 47, 46] >>> ^D % This (reachover) version runs all the tests which the gmake version does. % make t cd bin && make t cd /home/agc/local/micropython/bin/../dist/unix/../tests && env MICROPY_MICROPYTHON=/home/agc/local/micropython/bin/micropython ./run-tests pass basics/0prelim.py pass basics/andor.py pass basics/array1.py pass basics/array_add.py pass basics/array_construct.py pass basics/array_construct2.py ... pass unix/ffi_callback.py pass unix/ffi_float.py pass unix/ffi_float2.py 474 tests performed (15812 individual testcases) 474 tests passed 5 tests skipped: cmd_showbc cmd_verbose machine1 machine_mem extra_coverage % The sources are available from github: https://github.com/micropython/micropython micropython release at: https://github.com/micropython/micropython/releases Sources for 1.5.2 taken from: https://github.com/micropython/micropython/archive/v1.5.2.tar.gz Alistair Crooks agc@@netbsd.org Wed Jan 13 17:15:30 PST 2016 @ text @@
