I changed this to 'delay(1) ' and went from resting 100 fps control inputs/230 fps control inputs to resting 400 fps and 700 fps with control inputs. The first thing I noticed was the sample rate for the controls were higher, which allows for quicker reaction and better feel on the track.Ģ020 Update: Interesting change: I was looking at the RCUSB4 code and saw that there was 'delay(8) ' in the void loop, which in Arduino means 8 milliseconds every time it goes through the loop looking for control inputs. After calibrating the USB Controller (the Arduino Micro) in Windows, I started playing VRC as normal. It loaded up just fine, and after clearing up some confusion on the pinouts used to connect to the receiver, things got up and running quickly. A week later I got my board, but it took a couple days to get the time to get the code and libraries set up and uploaded to the Arduino. I thought this was a great idea and ordered one right away. I was contacted by Joel (another VRC racer) with the idea of using an Arduino Micro (USB enabled dev board). With all the delays and costs a DIY option was looking good, just in case I need a replacement for my older original VRC dongle. VRC did team up with 9-turbo to sell them for 60 Euros after some time. So, no official dongles were available anymore, and even some of the 3rd party adapters went out of stock like the MHW and 9-turbo. Unfortunately, the official VRC dongle went out of production due to permanent supply issues: The sim allows you to use your real life radio control transmitter and receiver by the use of a dongle that plugs into the USB port of your computer. It is a very faithful and complex simulation of R/C car racing. I race a simulator for R/C cars called VRC Pro (Virtual Radio Control). You can use the same DIY instructions below or I build, program, test, and ship one to you for just $40 in the US! Solid 700+ frame rate showing in VRC instead of variable. New V2.0 with updated code, new board that eliminates the USB cord, new connectors for easier channel connections.
