Do i need some kind of resistors? cause i got all connect directly to the board. After alot of time lost, just realized that the pins 0 and 1 on the arduino are switched, tought it starts 0, 1, 2 etc, but its 1, 0, 2 etc...im not at home but im sure thats the problem.

MsG 0 Report post Posted November 2, 2016 Yeah, I used this schematic: Let me know if it worked. For pedals and shifter you need some places which are already occupied for either one, so you need to solder some wires together. I thought it were a few 5V lines that I needed to combine. I suggest you first try it out on a breadboard, and then make it final. Share this post Link to post Share on other sites

bardocz 0 Report post Posted November 12, 2016 Hey Guys! Is it possible, to make it work with this board? Arduino copy I already have this, so that would be great. I'm not a programmer, but I guess if I change the pin number in the code to the correct ones, then this will work too. I hope I'm not wrong. I just got a G29, and I can't use my G25 shifter anymore.

Esdrasrk 0 Report post Posted January 12, 2017 My g27 does not have the original cable so I connected the cables of the x, y and z axes separately. I do not want to use the buttons, just the shifter. Can someone help me ? I tried to put the code straight but it appears that a variable has not been declared . In my connection the x-axis stayed with the red wire, the y-axis with the brown and the reverse gear button turned orange Share this post Link to post Share on other sites
Dinkpit 0 Report post Posted March 3, 2017 (edited) Hi Guys, Newb to coding and I am running into major issue. I have the Pro Mini 5v by Inland (this guy) and when I try to paste the code over I get an error while compiling:"Arduino: 1.8.1 (Windows 7), Board: "Arduino Pro or Pro Mini, ATmega328 (5V, 16 MHz)" C:\Users\TIM_DE~1\AppData\Local\Temp\arduino_modified_sketch_776978\G27_Pedals_and_Shifter.ino:8:36: fatal error: ./lib/G27PedalsShifter.h: No such file or directory #include "./lib/G27PedalsShifter.h" ^ compilation terminated. exit status 1 Error compiling for board Arduino Pro or Pro Mini." Do I just copy and paste the code? compile? or do i need to file in the: void setup() { // put your setup code here, to run once: } void loop() { // put your main code here, to run repeatedly: } Also, soldiering the wires on, do I use the power and grounding points from the write up, then just adjust the code for my pin out? Any help would be very appreciated! Edited March 3, 2017 by Dinkpit Share this post Link to post Share on other sites
VSteve 13 Report post Posted March 5, 2017 Hi Dinkpit. You have to copy G27_Pedals_and_Shifter.ino: file to an exact place. Maybe under the projects folder. Then open it with arduino. But Aruino pro mini doesn't have usb port. So you can not use for usb joy. It will not work. Share this post Link to post Share on other sites

When you will work a lot (and suck) with Pro Mini, Read :https://github.com/functionreturnfunction/G27_Pedals_and_Shifter "Required Parts/Materials SparkFun Pro Micro or clone (must be a 5V/16MHz ATmega32U4 with onboard USB)" And just buy a SparkFun Pro Micro (or any ATMEL mega 32u4 ) Share this post Link to post Share on other sites

In the process he lost the G25 shifter that he used mainly for Nascar and MX5 racing. To get a working shifter, there were several choices: Buying a new shifter: obvious but expensive Use the G25 shifter connected to the wheel without using the wheel: inelegant! Buying a Leo Bodnar interface (http://www.leobodnar.com/shop/index.php?main_page=product_info&cPath=72&products_id=188): cheap and easy Build our own interface: even cheaper and more versatile We chose the latter option to have the best possible control on the gear shifting logic: the stock G25 shifting logic is somewhat buggy, leading to quite frequent mis-shifts. Having full control of the software also allows adding some new functions: a handbrake mode seems the most obvious as the G25 shifter has all the necessary hardware. In the following posts I will explain all the steps required to build a G25 shifter to USB interface, based on a Teensy 2.0 board. This writeup is split into 5 chapters, each chapter being one post: Chapter 1: Hardware and tools required Chapter 2: Wiring and canning Chapter 3: Software Chapter 4: Tests and configuration Chapter 5: Conclusion Hello I need some help.

I'm new to his and still leaning. Thank you! It is not very difficult: Hardware: from what I read the sensor needs GND, VCC and signal connection (3 wires). The signal output needs to be connected to an analog input of the Teensy board. The first unused pin is A5 (pin 16).

However make sure your board is really a Teensy and not a knock-off advertised as a Teensy: the Teensyduino environment will usually not work with those boards.
