Here is a gamer that installed some new gauges into his rig. The gauges are controlled by an AVR mega microcontroller which has been programmed in C++ and AVR GNU-GCC.

“Here’s a quick video of me running no-plate daytona with 100% tape so the motor blows up. The gauge on the left is setup as a fuel gauge since I haven’t gotten a fuel gauge yet. The warning light above the oil temp gauge is actually the yellow flag light, since I haven’t gotten a light for that yet, like the ARCA cars have. The oil temp light isn’t used by NR2003. Everything but the warning lights work so far with rFactor. In rFactor, i have the fuel gauge setup as 20 gallons or more reading maximum.

My DIY racing simulator, works with NR2003 & rFactor. There is no “off the shelf” control solution used to drive the gauges. Created using telemetry examples by Papyrus & ISI, powered by an AVR mega microcontroller. Programmed in C++ and AVR GNU-GCC. The sunpro gauge on the left is set as a fuel gauge. None of the gauges have been altered in any way.”
