PyPak is a Python library for communication with Campbell Scientific data
loggers through the PakBus interface. It may be useful for people who would
prefer to use their own Python scripts to communicate with their data logger.
The software has been developed using Python 2.5 on Debian Linux and a CR1000
data logger with a NL115 ethernet interface and documentation available from
Campbell Scientific [1, 2]. In principle, it should also run on other platforms
and over a serial connection. However, this has not been tested. You should run
at least run OSVersion 17 on your data logger to make sure that some critical
bugs have been fixed.
Things that have been implemented:
- encoding and decoding of PakBus packets (PakCtrl & BMP5)
- reading and adjusting the data logger's internal clock
- file upload transactions
- file download transactions
- file control transactions
- retrieving table definitions
- retrieving table data
- reading and setting of DevConfig settings
- basic handling of DevConfig control messages
Things that are not yet implmemnted:
- DevConfig fragment handling
- one-way data transactions
- table control transactions
- install Python on your system
- copy the file from the "python" folder into your Python search path
How to get started
Try the examples in the "examples" folder:
IMPORTANT: to run the examples, you have to adapt the host name/address (for TCP/IP
connections) and the PakBus IDs for your computer and data logger in the file 'pakbus.conf' first! shows the clock offset between your computer and your data logger lists files on your data logger outputs the table structure from your data logger outputs the compile status of the (running) program
loggerd: A more complex example code that uses PyPak for communication between a PC, a CR1000 data logger and a MySQL server.
All examples only read data from the logger and should not be able to destroy anything. However, you should not try them on a logger taking mission-critical data. I cannot take any responsibility for lost data or damaged equipment. Backing up your programs and data first is strongly recommended.
