PJDL – Multi master, software emulated one wire data link in 171 lines of code
- gioscarab 9y agoPJDL v2.0 requires 1 or optionally 2 wires and no additional hardware to handle one or many to many communication on a single channel or bus. It can be run on low performance microcontrollers sharing a common direct pin-to-pin connection. It is a valid alternative to 1-Wire because of its flexibility and reliability. Bus maximum length is mostly limited by resistance of the common conductive element used. It has been tested with up to 50m long insulated wires, results demonstrate the same high performance achieved with shorter lengths.
