@Aganyte: il est possible que la FFB controller bloque sur attente de la réponse de la DriveBoard au boot, et donc refuse la communication avec le BFF.
Je ne connais pas les différences entre les deux versions de code pour me prononcer sur le comportement de l'une ou l'autre des versions.
Côté BFF, malheureusement je n'ai pas plus d'info que le fait que la carte ne réponde pas lors du handshaking de version à la connexion.

@ShinkoNet: as Aganyte explained, you might encounter a communication error between the FFB Controller and the servoboard, and it could be that the FFB Controller is locked waiting for an answer from the midi servoboard during its own initialization. When connecting, the BFF PC software will send a "V"ersion command during handshaking, which should be acknowledged by the FFB controller in less than 1s. Here it seems like the FFB controller is not responding in time.
Please check again your connection between FFB to the midi servoboard connection.

Hello, it took a while, but it is now working. Aganyte and I sorted it out and we found that my FFB board was not sending any inputs (only receiving) so we flashed a custom version that doesn't wait for the FFB to send anything back.

Hello (sorry for English),
I am trying to use BackForceFeeder with a 838-14174 MIDI Drive board.
The drive board is tested working (runs great when connected to a Sega NAOMI running Initial D 3), as well as the FFB Controller Pro (Aganyte has confirmed the MIDI Tx+- and Rx+- are fine on the board, we have tested the connection.)

I am having issues with force feedback using the FFB Controller Pro's firmware (PC_To_SegaFFB_MIDI, PC_To_SegaFFB_MIDI_4Views).
If I run PC_To_SegaFFB_MIDI_4Views, I get a connection (but with errors, since it is incompatible with the MIDI Drive Board's firmware)
https://pastebin.com/xpUgkU45
The motor turns the wheel to the right, but it does not go back to the left, and my oscilloscope confirms the drive board is not sending back any data while it waits for the motion to end.

I am trying to use the PC_To_SegaFFB_MIDI_Bis firmware instead, as I believe my problem is the same as seen here: https://www.youtube.com/watch?v=lFiZWJb-KAU

However, BackForceFeeder cannot interface with the FFB Controller when this firmware is flashed.
I get this error:

Going directly to the COM Terminal in Arduino's IDE, I can successfully connect to the FFB Controller myself.


Is there a reason why BackForceFeeder cannot connect to the FFB Controller Pro while it is running PC_To_SegaFFB_MIDI_Bis ?

Hi Aganyte,

I really appreciate your efforts in doing this!!
I also have an Initial D Arcade Stage 3 cabinet.
Mind if we can PM to order a FFB Controller board?

Thank you

Keep up with the good work too! 

Bonjour! (Hello!)

I'm an Australian arcade cabinet owner.
I have an Initial D Arcade Stage 3 in my garage.
Racing and rhythm games are my favourite.
When I'm not gaming, I'm normally creating my own music compositions.

Pleased to meet you!
