OBD2 Speedometer Badge and Development Tool
This unit is fully-scriptable using the PAWN language and has its own SDK.
It features 448 RGB LED's arranged in an arc around the gauge perimeter that use a 12-bit color space (4 bits per color). Refresh rates can achieve ~20 frames per second!
There are two HSCAN channels routed to the HSCAN pins on the OBD2 connector (6 and 14) and the MSCAN pins (for Ford) on pins 3 and 11. Using the scripts, many combinations of gateway functionality between the two CAN channels can be created - making this a valuable tool for automotive hacking and development.
The badge can be powered through the micro USB connector, the OBD2 connector, or the included 1100mAh LiPo battery. The battery charges via USB or OBD2.
Scripts are created in PAWN, compiled, then loaded onto the unit for fully autonomous operation. USB connectivity to windows PC allows for both reprogramming and real-time communication with device during operation. See the user's guide page for an overview of the process.
Two push buttons can be used for script control. The unit features 128kB script space and 68kB RAM accessible by scripts. This allows for very large scripts (thousands of lines of code).
The unit ships with a pre-installed script that contains many examples of using the display and buttons. This demo script, along with many other demo scripts (including one that turns the badge into an RPM/Speedometer using OBD2), are included in the SDK.
