This is a very daft implementation of an OBD logger. Using the ISO-9141 OBD-II protocol and a VAG COM cable (VAG COM cable, KKL 409.1, having the FT232RL chip by FTDI) This program was written in order to interface with a 2005 lotus elise (with the T4 ECU), however a different definition file may be used in order to interface with a variety of cars. Within the program there are some simple controls including a check list of loggable parameters. The program is a work in progress. This program uses Java 8, I think.

It also uses a Java D2XX library for the FTDI cable: 'JavaFTD2XX-0.2.6.jar' Embarrassingly, I cannot figure out where I got this library from. Download the FTDI drivers (for the VAG com cable) at: In order to use the pre-compiled version of Daft OBD download the following files and place them in the same folder on your computer: DaftOBD.jar also download the FTDI drivers as a setup executable, unzip and install them. This should enable the OBD program to work. When the program first runs, it requires that you select a save location for data logs that the program generates. It also requires you to select a valid definition file which outlines PIDs which are able to be polled. After choosing a definition file, restart the program. An example definition file is included: '2005 Elise OBD parameter definition.txt' When selecting an OBD cable to use, the program is a bit buggy if the cable is not plugged in before the program is started.

This device is a microcontroller which is designed to interface a personal computer or laptop with a vehicle's On Board Diagnostic (OBD II) interface. It is intended to function with all protocols used by vehicle manufacturers to implement the OBD II system as defined by SAE and ISO specifications. The OBD II system became mandatory for 1996 and up vehicles, but some vehicles were already fully or partially compatible with OBD II requirements prior to 1996. The chip is not suitable for the earlier vehicles such as OBD I.

After choosing a definition file, restart the program. An example definition file is included: '2005 Elise OBD parameter definition.txt' When selecting an OBD cable to use, the program is a bit buggy if the cable is not plugged in before the program is started. OBD II diagnostic interface pinout. OBD-2 ISO 9141-2 (14230-4, KWP2000) simple RS-232 cable. Hyundai OBD II diagnostic interface pinout; Kia OBD II diagnostic.

The device is intended to function as a simple scan tool and is capable of sending and receiving any OBD II message defined in SAE J1979 for any of the three types of OBDII bus implementations (PWM, VPW, ISO 9141-2). It can also be used as an inexpensive interface for custom instrumentation monitoring various vehicle parameters such as speed, RPM, coolant or intake air temperature, engine load, intake air flow rate, etc. Download game need for speed carbon rip indowebster indonesia.

Harvestman the biology of opiliones arachnid galaxy. However, mating interactions can proceed through a series of stages, with opportunities for assessment at each stage. We compared whether male or female size predicted mating interaction outcome across several stages of mating in five species of North American leiobunine harvestmen (commonly known as daddy longlegs).
