| PIC18F4550 as a 4 player arcade joystick (only 3 working) |
 Posted: Mon Jun 19, 2017 10:20 pm |

Hi,
I am developing an USB composite device with 4 HID Joystick interfaces, 16 buttons each, using a PIC 18F4550, for myself. So far I am able to make it work as a 3 player usb arcade, but I cannot make the 4th USB endpoint to work at all and I can't find the problem.
If I make it a 3 player arcade joystick, I am able to send to Windows the button keypresses of each joystick., but when I try sending anything to the 4th one, then all of the others stop receiving data. Actually, even if I try to send data only to the 4th endpoint, it won't work. I double checked that I wasn't missing any updating on offsets on descriptors as I was copy pasting from 2 to 3 and then to 4 players (adding interfaces to the composite device).
Before I quit trying, I decide asking for some help from you guys. Is this even achievable? Here is my code:

A couple of comments, though I've not played with this....
1) Try reducing the buffer sizes. There may be a 256 byte limit somewhere, so 32 byte buffers may be needed once you have >3 devices.
2) Look at the HID2 example. They only generate one interface, but then two endpoints. Might be worth trying to base on this. |

This did not solved the problem, so I changed it back to 64 bytes.

This totally worked! Thanks man, you rock!
------------------------
May I abuse of your knowledge just a little bit more? There is only one small thing that was bothering me previously and it still is:
On the USB_STRING_DESC, I've set the interface names I'd like to have Windows recognizing for each interface. But no matter what I write there, all of the interfaces will share the same string, even though I wrote different indexes of string descriptors for each interface as you can see in the above joystick.h file (when I had 1 interface descriptor for each interface, but now I am sharing the third interface descriptor with report IDs 3 and 4, so I think if this has a solution, I'll still have at least these 2 "interfaces" with the same name).
I would love if I could have it listed there as:
ARCADE #1
ARCADE #2
ARCADE #3
ARCADE #4 |

I think you would have to use the serial number.
Looking at the Windows stack definitions, it seems it'll always assign the same name to all the devices, but will allow the serial number to be different.
So a limitation of the Windows driver, but one that the serial number should allow you deal with.... |

| Hello Ghostjager, I'm working on an arcade joystick too. Please, could you post the working (modified) code for 4 joysticks ? Thanks in advance. |

Is not this part of the code wrong?
| Quote: | //endpoint descriptor 4 IN
USB_DESC_ENDPOINT_LEN, //length of descriptor ==124
USB_DESC_ENDPOINT_TYPE, //constant ENDPOINT (ENDPOINT 0x05) ==125
0x84, //endpoint number and direction (0x84 = EP4 IN) ==126
0x04, //transfer type supported (0x03 is interrupt) |
Would not it be 03? |
