11/20/2005 - The MicroOBD application is available for download. The application checks with the vehicle computer for supported Mode 01 PIDs and will display the live data from all available sensors. The supported sensors can be disabled/enabled by single click/tap on the gauge. Disabled, but supported PID will change its color to red. Unsuported sensors will be colored gray.
The application features log to file (.csv), packet data mode for ELM v2.0 or newer, US / SI (metric) values conversion, ELM version display and auto-continue. If the program detects errors or no response from the ELM interface, it will wait 5sec. and reset the chip. In case the automobile is turned off, the program will try every 5sec. until the PPC goes to a sleep mode. After the PPC is started again and the program receives the focus, it will reset the ELM chip and continue. Resetting should not affect currently selected for monitoring sensors.
The .csv log file will have only the values when the interface is working and connected to the car. Only enabledfor monitoring sensors will be logged.

MicroOBD is written in eVB. It requires eMbedded Visual Basic runtime in order to run on PPC2003 or newer PocketPC devices. The runtime is a free download from Microsoft website. |

|
|
The source code is available for free download and use, as far as this or any modified version continues to be distributed for free. To take a look at the code, please agree and download.
Required for proper built are the eMbedded Visual Basic 3.0 from the eMbedded Visual Tools 3.0 2002 Edition package, and the PocketPC 2002 SDK or, alternatively, the SDK for Windows Mobile 2003-based PocketPCs, all of which are still free downloads from Microsoft. |
