RP1210 0.0.2

A Python32 implementation of the RP1210C standard.

pip install rp1210

A Python module for interacting with RP1210 adapter drivers, following the RP1210C standard. Contributions welcome!

This module was written and tested with Python 3.9, 32-bit. Older Python versions have not been tested and may not be supported. 32-bit Python is required because RP1210 drivers are all 32-bit, and can thus only be loaded with 32-bit Python. A 64-bit implementation via MSL-LoadLib is planned and may be released as a separate module.

This module is currently in alpha, and changes to core functionality may happen. Not all aspects of the RP1210C standard are implemented. Currently, my focus is on J1939 communication. Other protocols have significantly less support.

While I try to provide adequate documentation, the RP1210C standard is owned by TMC, not me, and is not reproduced here. For a complete understanding of the RP1210 standard, you must purchase and read the official RP1210C documentation from TMC.

Official RP1210C documentation can be purchased from TMC at this link ($37.50 at time of writing): https://www.atabusinesssolutions.com/Shopping/Product/viewproduct/2675472/TMC-Individual-RP
