Thanks. I'll try it next week.
Hi thanks for this info squibcakes!
i think this is exactly what I need to move forward.
I have EasyHid and have created the generic files but now need to understand the descriptor files.
one question...don't know where to find 'Descriptor tool'. is it a text editor? where do I find it?
cheers.

Ahhh yes, one of my favorite programs.Quote:

DT.exe :)

Gogsmack01,
Writing descriptors is a headacke. I have managed to modify a few descriptors to do what I want, but always after many hours of banging my head against the walls.

I can't getg it work. can someone upload descriptor file?
Thanks
Pedja089,
Look at the link that Darrel provided above. In there you will find a document about HID descriptors. In one of the appendixes at the end of the document they have descriptors for a mouse, a keyboard, and a joystick. That should help you.
Get one of the sample descriptors that come with PBP and modify it accordingly. It should work.

Hi all
I ran into a problem right at the start when my basic compiler threw some error messages. I am sure it is related to the flavour of PicBASIC I am using.
squibcakes you are using PBP (PicBASIC Pro), I am using Proton+.
the difference can be seen in variable declaration eg.
dog VAR Byte 'PBP
Dim dog Byte 'Proton+
Hope I am not talking mince here, anyone can support this theory I'd be glad to hear.
Once I sort out the source of compile errors I can forge ahead.
cheers.
Gordon.
OK
it is
Dim dog As Byte 'Proton+
cheers.
Gordon.
After reading the guide carefully and preparing the code, while compiling, i get varios errors about Simbols not previously defines.
this happens with USBDeviceInit, USBDeviceTasks GetUSB and PutUSB???
Should something be included here and what??
Thanx
Found a work arround.
Copy the hid_desc.bas file and all associated files to your working directory.
Copy the text made by DT.exe and changed by the ways of the Dummy Manual, into the 'ReportDescriptor1' part, overwriting existing code.
This should do the trick.
By this way I created a 6 axis,16 button pedestal.
Have fun

Can you upload project or pbp code and descriptor file?
A better way is to "INCLUDE" the file like so . . .Quote:

Hi,
I have got my usb joystick working, but my axis starts in the centre moves to the right, to the left side then back to the centre as i increase the pot.
I am doing a simple "adcin, 0, USBBuffer[0]" as in your example.
I tried shifting the result 4 bits to the left but this just mixes it up onto 2 axes.
What am I doing wrong?
Doh, all i had to do is add 128 to the result, boy do i feel foolish :-)
Regards
Bob...
Hello all,
I am trying to convert my old joystick to USB Joystick.Since i am kinda new to USB,i plan to take this advantage to learn how USB works.I have tried CDC before & now HID.As a starting point,i searched for a example code & bumped to a site (www.starlino.com),an accelerometer based joystick.I downloaded the codes (which is in PBP) & researched the codes.After going through the USBDesc & tried the code (which worked very well) & i plan to expand it from original (2 Axis & 6 Buttons) to 3 Axis,Throttle & 8 buttons.I have modified the USBDesc & added some lines in source.To my suprise it connects to the computer (ting tong) & showed the axis,throttle & buttons in the gamepad configuration but it freeze in there.Whenever i press any of the buttons,i didn't work..i mean nothing happened.I have tried few methods but didn't work.Can anyone help me??.Attached codes together.
*PS - The attached code is only for x,y,z axis & buttons.
You help is kindly appreciated :)
Hello all,
Sorry.The above attached USBDesc have throttle & not Z axis.I have modified few of them but the result are the same.No response.One way around the Buttons should work,but in my case none of it is working.
hello all,
Ok.We make it simple here.I added Z axis but in the gamepad configurator it shows the Z axis but not working...
Ok , A 4 axis joystick with 12 buttons and a hat switch:

Hello gentlemen, im new to the forum and dont really know much about usb or PBP3 so sorry for the may-be dumb question since i use HITECH-C
i did all off the dummies guide stuff but in the end, it asks me to compile, compile where? in MPLAB?
ok so i compiled on mplab using the PBP3 compiler on the 15 trial version and it gives me the following:
ERROR: Macro USBINIT? not found in macro file.
ERROR: Macro USBSERVICE? not found in macro file.
ERROR: Macro USBIN?CBBL not found in macro file.
ERROR: Macro USBOUT?CBBL not found in macro file.Halting build on first failure as requested.
BUILD FAILED: Tue Apr 22 22:28:08 2014
apart from this, i would really like to know where do i configure my PIC18f2550??
do i make a .c file?? (i.e MY_JOYSTICK.c)
and work from there??
how do i prevent/correct this compile errors??
also, where can i find the circuit diagram for this "dummie" joystick, thanks a bunch guys and see you later :D
sorry this is what im getting now
