Wiring of buttons.

[lazenyuk-dmitry]

Somehow very difficult in your project with buttons. And you can make more buttons. I think you could implement the same button connection as in this project like https://github.com/vsulako/AFFBWheel.

Hi Dmitry,

Tnx for your feedback.

My implementation of buttons is the same as in the project you mention. I'm using a standard shift register protocol, except that instead of shift register chips I'm using Arduino nano that simulates a shift register and has 16 buttons. It is possible to just change one line of code and have the ability to read more than 16 buttons when using shift register chips stacked in series.

I believe that my wiring diagram shown on the button box wiring png is clear enough, there is all information one needs, but you are right there can be improvements I'll think about it and put a better picture. I did show an example of wiring one button, but the same goes for all other buttons, not sure what exactly is not clear there to you.

Best regards, Milos.

Here is the documentation, I have already put these in the release.

Bye, Milos.

This txt file contains details for connecting a second Arduino Uno or Nano board, that will act as a shift register (button box) inside a custom wheel rim

Ver. 1.01 - 2015-06-17 Ver. 1.02 - 2018-06-17, modified by Milos Rankovic

This sketch emulates Thrustmaster TX RW 458 Italia wheel allowing to connect arduino to TX RW wheelbase (may work for T500/T300 as well) and emulate button presses - up to 17 buttons can be connected to arduino, if you don't need a serial debugging

!!! There are 2 flavours of arduino boards - powered by +5 volts or +3.3 volts !!! !!! If you have +5V Arduino version - disconnect it from USB before connecting to a wheelbase !!! !!! Just power your arduino from TX RW wheelbase Black pin - it supplies +3.3V voltage (should be enough) !!! !!! don't connect USB +5V wire to TX RW wheelbase Black +3.3V - you'll get a collision !!!

Thrustmaster Wheelbase cable pinout (PS/2 connector, also known as mini-Din 6pin female): 1 - Green - not used 2 - Blue - GND (ground) 3 - White - MISO (master in, slave out - to read the data from the wheel) 4 - Orange - SS (slave select, or PL - parallel load, set it to 0 when you want to read the data) 5 - Red - CLK (clock impulses) 6 - Black - +VCC (+3.3 volts! if you have Arduino 5V version - use external +3.3V power or use the wheelbase power!!!)

Arduino UNO pins -> TX RW wheelbase cable pins

Arduino GND -> TWRX Blue wire (2) Arduino pin 12 -> TXRW White wire (3) (data from wheel to base) Arduino pin 10 + pin 2 (SS) -> TXRW Orange wire pin (4) (yes, on Arduino it's wired to two pins. 10 - SS, 2 - INT0) Arduino pin 13 (SCK) -> TXRW Red wire (5) Arduino +5V -> TXRW Black wire (6) (it gives 3.3V, but must be connected into +5V socket on arduino uno side)

Arduino Leonardo FFB (as wheelbase) -> Arduino Nano or UNO (as button box)

Leonardo GND -> Nano GND Leonardo 5V -> Nano 5V Leonardo pin 6 (DT_sw) -> Nano pin 12 Leonardo pin 7 (CLK) -> Nano pin 13 Leonardo pin 8 (PL) -> Nano pin 10 and pin 2

Button mappings (we send 8 bytes to wheelbase, first 16 bits are for buttons, the rest are unused - no more pins on nano)

Byte 0 1 – A (button 6) -> pin 7 (portD bit7) 1 – B (button 4) -> pin 6 (portD bit6) 1 – RS (button 12) -> pin 5 (portD bit5) 1 – Menu (button 9) -> pin 4 (portD bit4) 1 – Gear Down (button 1 = L_Pad) -> pin 3 (portD bit3) 1 – X (button 5) -> pin 9 (portB bit1) 1 – Manettino CCW (button 7, View) -> pin 1 (portD bit1) - if you don't use serial debug (UART TX) 1 – Manettino CW (button 8, Menu) -> pin 0 (portD bit0) - if you don't use serial debug (UART RX)

Byte 1 1 – Gear Up (button 2 = R_Pad) -> pin 8 (portB bit0) 1 – Y (button 3) -> pin 11 (portB bit3) 1 – LS (button 11) -> pin A5 (portC bit5) 1 – View (button 10 – under X) -> pin A4 (portC bit4) 1 – D-Pad Down -> pin A3 (portC bit3) 1 - D-Pad Right -> pin A2 (portC bit2) 1 - D-Pad Left -> pin A1 (portC bit1) 1 - D-Pad Up -> pin A0 (portC bit0)

Each push button has 2 pins - you connect one to Arduino, another to the Ground :) Pressed button gives you "1" (grounded signal), released = "0" (pulled-up to +VCC)
