USB HID Joystick & PPM-In program was created by hmjack2008

Just upload my program, DEVO10 for "USB HID Joystick".
(1) in Menu->USB page.
(2) press "DN" to enable USB.
(3) plug-in USB to PC, PC will detect Mass Storage & USB HID Joystick.
(4) press "UP" to enable send Joystick data.

So head tracker be an option soon, sweet

possibly option for 7e(hint)

Some details on how to add it to build would be handy for dim wits like me

Thanks,Phil

Basically, you would drop the files in the root dir, and add ppm_Init() after the Init() call in main.c

Note that is just from inspection I didn't try it.
it will override the normal inputs I think and isn't configurable, so it is more of a proof of concept than anything else.

Still, it is great work, and I look forward to spending more time looking at it.

So would work for 7e& others or just 10?

I think I am going to tackle the USB Joystick for the Devo 8, my goal is to have it working by tonight.

may be you need change "mixer.c" for DEVO8 & DEVO7 :

(1) change : "7" to "5"
(2) change : "15" to "13"

=========== mixer.c ===========

#define devoCH_size 4+1 //devo7;8;10 = 5;5;7
#define devoSW_size 4+1+8 //devo7;8;10 = 13;13;15

/******************** Joystick ********************/
#ifndef EMULATOR
if (JoystickEn && PrevXferComplete) {

if (i<devoCH_size) { // devo7;8;10 = 1~4: Aixs; 5~6:AUX4~AUX5
Joystick_Buffer[i+2] = (s8) ((raw)/79);
} else {
if (i<devoSW_size) { //switch 1st-byte
if (raw>0) {
Joystick_Buffer[1] |= (uint8_t) 0x01<<(i- devoCH_size);
} else {
Joystick_Buffer[1] &= (uint8_t) ~(0x01<<(i- devoCH_size));
} //if (raw>0)
} else { //switch 2nd-byte, devo7 not use
if (raw>0) {
Joystick_Buffer[2] |= (uint8_t) 0x01<<(i- devoSW_size);
} else {
Joystick_Buffer[2] &= (uint8_t) ~(0x01<<(i- devoSW_size));
} //if (raw>0)
} //else if (i< devoSW_size)
} //if (i< devoCH_size)

JoystickBuff = 1;
} //if (JoystickEn && PrevXferComplete)
#endif // #ifndef EMULATOR

I use "menu-> about page" to do enable ppmin.c and show the ppmin channels & signal-width.

(0) use trainer cable to connect
(1) in about page
(2) press "ENTER" to enable ppmin
(3) press "DN" to show the ppmin channels & signal-width

NOTE:
Do NOT plug in/out the trainer cable when ppmin enable !!

I got the problem .... if plug in/out when ppmin enable.
=> sometime, LCD become no display,
=> if LCD no display, need reflash to walkera fireware for recover.

====about_page.c====

static u8 _action_cb(u32 button, u8 flags, void *data)
{
    (void)data;
    if ((flags & BUTTON_PRESS) || (flags & BUTTON_LONGPRESS)) {
        if (CHAN_ButtonIsPressed(button, BUT_EXIT)) {
            PAGE_ChangeByID(PAGEID_MENU, PREVIOUS_ITEM);
        } else {
            if (CHAN_ButtonIsPressed(button, BUT_ENTER)) {
            #ifndef EMULATOR
            // ppm-in
            sprintf(up->tmpstr, "ppm: '%d'-'%d'", 0, 65535),
             GUI_CreateLabelBox(0, 55, 128, 8,&TINY_FONT, NULL, NULL, up->tmpstr);
            ppmin_TIM5_Init();
            ppmin_Init();
            ppmIN = 1;
            }
            if (CHAN_ButtonIsPressed(button, BUT_DOWN)) {
            ppmin_Stop();
            sprintf(up->tmpstr, "ppm#: %d-%d-%d",ppmin_num_channels,ppmChannels[0],ppmChannels[ppmin_num_channels]);
             GUI_CreateLabelBox(0, 55, 128, 8,&TINY_FONT, NULL, NULL, up->tmpstr);
            }
            // ppm-in
            #endif    // #ifndef EMULATOR
            }
        }
    }
    return 1;
}

Hi
Well i give it ago awhile back and tried to build 10c and 7e no joy lots of build errors. I know you did this for 10c only then added 7e. hoping either you've done more with it or some pointers on how it should be built. I did try build just Hid then PPM and then both.

thanks,Phil

Edit PB:
Removed entire post due to discussion of illegal software. the zip itself is the usb joystick code and looks ok.

Please read the message posted on the forum page. No discussion of subverting copyright will be tolerated on this board.

Sorry, I included the illegal message, and thanks PhracturedBlue removed these immediate.

below is my updated :
(1) for USB joystick,
(1.1) change for DEVO7;8;10;12.
(1.2) rearrangement the sequence of axis.

(2) for PPM-In
(2.1) the program not compatible with Walkera f/w.
(2.2) the ppm-in need special audio cable to connect.
coach(audio-left, ppm-out) --to--> trainer(audio-right, ppm-in)

Too bad you included the crack... Good work on the ppm in and usb joystick support but the crack will get this post deleted as soon as pb or fdr see it.

There are 10 types of people in this world. Those that understand binary and those that don't.

is the ppm in with usb hid ?

Phoenix R/C is cheap enough compared to few crash's. Guy puts more updates out than PB

Even if you sell up phoenix holds it's value and never up for sale to long. Small heli's hard to say how good but 450 up and trex600 is perfect.

Which one is the TIP of the plug? I can't recall off the top of my head. If the TIP is left for ppm out, then maybe the standard "mono" cable will work for trainer and sim without having to use an adapter?

Can't wait to see both of these features working... will be great!

(And yes, Phoenix is great! I have Phoenix and RF6.5 but I shouldn't have bothered with RF6.5...)

well once have a working code you'll only have 2 options so i think i can work it out

I'm thinking it maybe simple way to add multipole switch's ok maybe hard to configure/not supported but simple/easy.

I started with reflex and at the time thought it was good till started flying with heli pilot and saw how much better it was. And I'm not going to comment about realflight as not to start flame war.

I've started implementation of the ppm-in capabilities.
So far I only have the menuing created. The actual ppm code is not yet ready.

My idea is that there are 2 modes for PPM-in:
1) Trainer mode: In this mode each input channel is mapped to an output of the transmitter when the relevant switch is enabled, otherwise the channels act as normal

2) FPV mode: in this mode we enable a set of new inputs that can be used like any other analog input. this will allow for head-tracking or whatever other external inputs you like.

The PPM controls will allow specifying the PPM parameters (similar to how the PPM-Out controls work), as well as the channel order (when using train mode)

Well that's a lot more than expected. Trainer function going to be life saver

Friend dropped quite a lot money into mid range quad and only flown on sim and watched me. He's not the type to give tx when i first ask for it

FPV great!!!

Thanks, Phil

IMO even with the only FPV mode one can manage both situations.
I think trainers don't always let control all channels by the tranee anyway...

The point is there should be PPM in inputs assignable to any channel source, All the rest can be done with switches...

I agree it could be done with just extra inputs, but configuration would be cumbersome as you'd end up needing to tune every model for train mode. With this configuration, you can very easily configure an existing model for work with a trainer. It is a good point about some channels not being mapped. I'll make sure you can disable the mapping of the input channels in train mode.

Before is based on my own ideas in this ppm-in program.
I use my JR-10S (9 channels ppm-out) for DEVO10 ppm singals input.

So, my program not compatible walkera firmware.

Today, I use Arduino to do out put 8 channels ppm signal (Student mode simulation ).
The DEVO(walkera firmware) can use on Coach mode.

Now, I finally know the walkera's algorithm.

well, I have the code all put together, but it doesn't actually work. The code hmjack posted uses GPIOA.10 as the trigger (the uart-rx pin), but as far as I can tell, that pin is not connected to the trainer port at all. While the jack supports a 3-pin 1/8" plug, the wiring only seems to connect the tip and ground and not the middle terminal.

Thus I can probably setup GPIOA.9 to work (though it will be impossible to use ppmin and ppmout at the same time which is too bad). But hmjack seems to have been able to get it to work with GPIOA.10 and I am not sure how.

It is odd because the plug on the circuit-board exposes both pins, but only one seems to be attached to the phono plug.
