Hello, I am really new to python and really have not programmed much since college, I played with it a little now, and it seems to be a tool I feel comfortable implementing a personal project in.
I wish to communicate via a serial port to a device that is using COBS. I wish to configure it and then receive data at an interval and store it in a rrd. The device itself receives telemetry information from other devices, and this telemetry info is going to get graphed and made available via a web page. The serial port will be com or tty, for which I prepped by playing with pygarmin and miniterm. The device is working and communicable? via a program written in .NET by a friend of the friend who gave it to me. The program has so many things I wish to change that it would be easiest to start from scratch. I have some of the source for bits and pieces that may be needed. The data coming in/going out will be COBS encoded, which changes/escapes all 0x00 bytes, then uses a 0x00 byte for the framing. COBS theory is explained here: http://www.stuartcheshire.org/papers/COBSforToN.pdf and it looks like a version written in c is at: http://gtk-gnutella.sourceforge.net/doxygen/cobs_8c.htm I would initially be happy creating a cobs.py and then modding the initial 1.1 release of miniterm and seeing if I could listen to the device... The device will be sending packets of 2-12 bytes at regular intervals (99% will be 7 byte packets every minute or so), and I can just move the serial cable over from the com port with the working application to the cobs-miniterm one to see if I am getting the right. Thanks in advance! -mike clearwater, fl __________________________________ Yahoo!
