We need a python script that can run on a linuxbox with a CANBUS card installed. This box will simulate sensors giving voltage to a processor on the other end of the can bus. We need to be able to rerun log files with values that need to translated into voltages and then transmitted at the current rate. A web interface is needed to administer the program. The web socket must be part of the program no bloated installation like django or such is wanted. We have a proof of concept script that runs the sensors on the bus and the hardware is ready. Script literally needs to do data parsing and organising with the different datatypes. Have more precise documentation and example dumps and scripts and log files. nothing fancy needed just a stable script. Must run with Python3 and use the python-can libs.

Hello, I believe that I am particularly qualified to build this code for you. I have 3 years of experience building software drivers to communicate with energy meters, implementing various protocols at the byte-stream level (modbus, DLMS, ION, among others). I also have 2 years of experience building data-intensive python scripts, including webapis. From your proposal, I understand that I would need to build the following components: very basic webinterface with three pages * settings * static sensor mode * logfile rerun mode settings page: * read and parse config file * list of all sensors * button to remove sensor * fields to define analog sensor * button to add analog sensor * fields to define serial sensor * button to add serial sensor * save config to file static sensor mode page: * read and parse config file * list all sensors * add checkbox for each sensor * start button * stop button logfile rerun mode page: * select logfile from disk * upload logfile * field for frequency * start button * stop button CANBUS data transmission module: * must be started in another thread/process so that webserver can handle future requests, such as stop * receive parameters from sensor configuration * in the case of serial sensors, read in the NMEA template * in the case of logfile rerun, load and parse the log * pack CAN messages correctly and send them in the correct interval * signal between threads/processes to cancel sending when a stop signal is sent
