Issues with Arduino Mega about vjoyserialfeeder HOT 3 CLOSED

Hi, I'm not sure why the number of channels is wrong. Anyway if you are not using the analog channels you should change the code to:

#define NUM_ANALOG_INPUTS 0
byte analogPins[] = {};
#define NUM_DIGITAL_INPUTS 12
byte digitalPins[] = {40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51};
#define NUM_DIGITAL_BITMAPPED_INPUTS 0
byte digitalBitmappedPins[] = {};

But I would recommend to use the bitmapped inputs like this:

#define NUM_ANALOG_INPUTS 0
byte analogPins[] = {};
#define NUM_DIGITAL_INPUTS 0
byte digitalPins[] = {};
#define NUM_DIGITAL_BITMAPPED_INPUTS 12
byte digitalBitmappedPins[] = {40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51};

This will allow all 12 buttons to be packed in just one channel (2 bytes/16bits). Otherwise, with every frame you are sending 12 16bit channels of which really only 1 bit has any meaning, so it's a waste.

Thanks for the insight. I've reconfigured with your suggestion but still having issues with these momentary buttons.

Firstly when I upload the script I get the following warnings:

C:\Users\William\Desktop\vjoy-serialfeeder\Joystick\Joystick.ino:15:0: warning: "NUM_ANALOG_INPUTS" redefined
#define NUM_ANALOG_INPUTS 0

In file included from C:\Program Files (x86)\Arduino\hardware\arduino\avr\cores\arduino/Arduino.h:258:0,
from sketch\Joystick.ino.cpp:1:
C:\Program Files (x86)\Arduino\hardware\arduino\avr\variants\mega/pins_arduino.h:29:0: note: this is the location of the previous definition
#define NUM_ANALOG_INPUTS 16

Secondly, in the vJoySerialFeeder App I now show only one channel detected, so I configured a bit-mapped button. Tied it to channel 1 and here are my settings for each bit:

Nothing seems to be working, I'm not getting any feedback or seeing any button response in the vJoy Game controller.

Oh, I see now. I had no idea that NUM_ANALOG_INPUTS is actually #define that is used in Arduino code itself =O
I'll have to update the sketch to use another name. Please replace every instance of NUM_ANALOG_INPUTS inside the .ino file with something else.

About the the other problem: I completely forgot that recently there was update of vjsf that is probably the reason for this.

Some time ago it turned out that IBUS uses only 12bits (0-2047) for each channel. This leaves 4bits free from every 16. Thus FlySky is using the 4bits of three consecutive channels to pack another 12-bit channel. For this reason if you have 3 channels (2 bytes/16-bit each) in the frame, you can pack inside one additional 12-bit channel (3 times the 4 unused bits).

This is the reason that you got 37 channels instead of 28.
28/3 = 9.333... So with 28 16bit values you can pack 9 additional channels, giving the total of 37.

Newer AFHDS3 tranismitters pack these additional channels. Within the standard 14 channels they pack 4 additional for total of 18. That's why I've implemented this in vjsf, but also made it possible to use the old behavior that uses the full 16-bits for each channel. You have to click the Setup button next to the IBUS protocol selector and there choose 16-bit channels.

I had to document this but I completely forgot about all this.
