The ELM327 is a programmed microcontroller produced for translating the on-board diagnostics (OBD) interface found in most modern cars. The ELM327 command protocol is one of the most popular PC-to-OBD interface standards and is also implemented by other vendors.
OBD-II is an improvement over OBD-I in both capability and standardization. The OBD-II standard specifies the type of diagnostic connector and its pinout, the electrical signalling protocols available, and the messaging format. It also provides a candidate list of vehicle parameters to monitor along with how to encode the data for each.
Although this gives a more versatile trip computer compatible with most modern vehicles, the ELM327 chip adds significant cost to the circuit and requires a significant supporting circuit for different protocols. It removes the complexity of interpreting the various OBD protocols. STN1110 which is software compatible with the ELM327 ...
OpenXC could offer a standard interface, similar to the ELM327 interface. An OBD interface may be complex to implement, while the OpenXC API is designed to be friendly for application developers; Possible advantages of using the OBD interface include Use well established existing OBD interface hardware and software, e.g. using the ELM327 protocol
As Holocaust Remembrance Day is marked on Jan. 27, a town in southwestern Germany unflinchingly confronts its past and reaches out to Jews.
JD Vance is “fulfilling his promise" to American voters as he makes his first trip as vice president to Damascus, Virginia, on Monday to visit hurricane-impacted areas.
OBD-II PIDs (On-board diagnostics Parameter IDs) are codes used to request data from a vehicle, used as a diagnostic tool. SAE standard J1979 defines many OBD-II PIDs. All on-road vehicles and trucks sold in North America are required to support a subset of these codes, primarily for state mandated emissions inspections .
Citadel CEO Ken Griffin on Tuesday called aggressive trade talk from the new Trump administration" 'huge mistake," producing chaos that in Griffin's view poses an "impediment" to economic growth.
