Simulate C's switch statement (Python)

2016-12-11T16:28:50-08:00

Python recipe 580730 by Vasudev Ram (c, features, language, python, switch).

This recipe shows a Python construct that can behave somewhat like C's switch statement. It is not a perfect one-to-one simulation. But it does have some of the features of the C switch. One feature not supported is the fall-through feature in C's switch.

An old game I created freshman year of college. For use on Windows OS only. (The code contains a few Windows system calls.)

csc prototype to arduino board with python API. part I (C)

2010-12-26T12:14:33-08:00

C recipe 577520 by cheeng shu chin (api, arduino, c, python, serial). Revision 2.

Few day ago, i'm try out arduino UNO robotic board. found it not that easy to use (C <--> Python). I wrote a arduino UNO prototype to serial API, which can interface to any programming Language. as long as the programming Language can interface to virtual serial port and using serial API, this recipe can be use... Requirement:

Upload this recipes to arduino uno with my prototype code (name "csc.pde" as below)

Base concept:

wait from serial reply "?" and ready for read
pass function name as string to arduino uno
pass all argument as string to arduino uno
read result as string from arduino uno

Can easy extend it to support:

python API(open source and i like most) in part II
other arduino board
Bluetooth with serial interface
any PC can control the arduino board easily via your prefer Language.
interrupt

Future add-on:

Json string passing to arduino
Json Reply from arduino
thread base design
Interrupt direct call

Please study it and extend it and share among open source members especially in python... :)

csc prototype to arduino board with python API. part II (Python)

2010-12-26T12:20:48-08:00

Python recipe 577521 by cheeng shu chin (api, arduino, c, python, serial). Revision 2.

This is the Python API for my arduino uno board. this is base on what i posted in Part I .. I didn't spend time to comments it... I'll do it once free soon. Please study it and extend it and share among open source members especially in python... :)

The file name is "cscarduino.py"

Add function to Python's builtin module through C API (C)

C recipe 579110 by airween (api, builtins, c, exten, python).

Add function to __builtin__ module through C API

Sometimes it need to embedding a Python script to a C code, and it references to a function, which also provided by the same C code. Then you have to import the module, as you defined in your C code.

But this import would be skipped, if you add your function to your __builtin__ module. In Python3 (3.5), there is the PyModule_AddFunctions() function, but in the previous versions, you can make it like this snippet.
