Hi all, I've looked through the threads about embedded Python that are a year and a half old, and I thought that I'd ask this question now to see if anything has changed. Has anyone, or is anyone working with Python in an embedded Linux environment? Mine is NO where near as constrained as a cell phone since I've got plenty of memory to work with, I'm just running a Linux 2.4 kernel ...

Hello, I've been trying to figure out the way the CORDIC algorithm works and I am not sure if this is the right place to post this, so feel free to point me in the right direction to get help. I usually code a quick prototype in python for verification and understanding of an algorithm I need to implement. For those of you who don't know Python but know C, you should be able to follow it s...

Apropos to the question "Python for DSP" in comp.dsp (http:// www.dsprelated.com/showthread/comp.dsp/243722-1.php): How fully object-oriented is Python? I'm doing an app that really wants to be prototyped in something Scilab-ish (i.e., interpreted so it's easy to do graphs or computation on bits of it), but which is seriously challenging Scilab's sorta-object oriented-ness. I'm running...

I was looking for Python modules for embedded systems, and I have found the following website: http://elk.informatik.fh-augsburg.de/da/da-49/ In the subdirectory http://elk.informatik.fh-augsburg.de/da/da-49/trees/pyap7k/lang/ there is a lot of GPL-ed code which may be used to interface Python to different I/O interfaces in embedded systems. I've managed to succesfully integrate the py-sp...

Greetings, I wish to transfer binary data in the simplest way possible from a PC to either an AVR or TMS320F2812 embedded target via USB. The PC will be running a Python/wx.Python program and use PySerial to send data out through the virtual COMM port produced by using a FTDI FT245BM USB-to-FIFO parallel interface chip on the target. Ideally this program will be useable on Linux as ...

Hi all, I've been working on a simple python 'compiler' targetting the AVR (inspired by Pyastra, the equivalent PIC program). The (rather bare) website is here: http://www.ecs.soton.ac.uk/~jb1403/projects/avrpy/ The code is fairly simple (though my tarballing skills leave much to be desired), and produces surprisingly clean assembly (optimal in many simple cases), though it only attem...

Hi! I have an application running on F1101a which I want to migrate to F2001 (I don't use all the I/Os and the lack of POR reset in F1101a is not a feature that I like). Now, I did all my firmware development under open source tools using mspgcc and their python driven tools to program MSP430 parts (I've used both the JTAG and the BSL). It was especially convenient for me since I'm usin...

Hi everybody. This may be slightly off topic - I am looking for an embeddable script interpreter or VM. If you know of any more appropriate groups to post to, please let me know. It should have the following features: - Stand alone interpreter (or VM) should have very small memory footprint (less than 500k on Windows). - Reasonably high level programming language (on par with python/Ja...

Has anybody worked with these? I'm having trouble finding any information about serial output formats. I've got this far: I've configured it for UDP, and sent a UDP packet with a string of ASCII alphanumeric characters as payload (using the Python socket module). The serial output then provides * a byte 0x02 -- perhaps ASCII STX, perhaps not * 4 bytes that could be the IP address of the...

I am not sure this is the best group, but it might be close enough. In our current project we use PSoC controllers from Cypress and we access our application by reading and writing variables (by address). To do so we parse the map file on the host to figure out the address of a variable and then send the address to the PSoC. Over time our host code (in Python) became more complex and w...
