ATTINY85 doesn't work with "TinyWire.h" and "DigiKeyboard" together in the same code

[Giova02]

Hi to everyone!
That's my first post here.
I'm trying to write presaved messages controling a digispark attiny85 using i2c communication with an esp01 in AP mode to control the system via smartphone.
Doing some tests I can now do everything I wanted to do but now, after adding the DigiKeyboard commands and lib, when I tried uploading the following I got this error..

C:\Users\10293_~1\AppData\Local\Temp\arduino_build_994554\libraries\TinyWire-master\twi.cpp.o: In function __vector_2':
C:\Users\10293_000\Documents\Arduino\libraries\TinyWire-master/twi.cpp:822: multiple definition of __vector_2' C:\Users\10293_~1\AppData\Local\Temp\arduino_build_994554\libraries\DigisparkKeyboard\usbdrvasm.S.o:C:\Users\10293_000\Documents\ArduinoData\packages\digistump\hardware\avr\1.6.7\libraries\DigisparkKeyboard/usbdrvasm165.inc:41: first defined here collect2.exe: error: ld returned 1 exit status Using library DigisparkKeyboard in folder: C:\Users\10293_000\Documents\ArduinoData\packages\digistump\hardware\avr\1.6.7\libraries\DigisparkKeyboard (legacy) Using library TinyWire-master in folder: C:\Users\10293_000\Documents\Arduino\libraries\TinyWire-master (legacy) exit status 1 Error compiling for board Digispark (Default - 16.5mhz).

Can someone help me to solve this pls?

Here's also the attiny85 code (I don't think it's a problem related to the esp01 code so i think that the attiny85 one could be enough)

`#include "KeyboardIT.h"
#include <TinyWire.h>
#define own_address 9

void setup()
{
TinyWire.begin(own_address);
TinyWire.onReceive(comando);
pinMode(0, OUTPUT); //LED on Model B
pinMode(1, OUTPUT); //LED on Model A or Pro
}

void loop()
{
}

void comando(int dato)
{
while (TinyWire.available())
{
char c = TinyWire.read();
if(c=='1')
{
digitalWrite(0, HIGH);
digitalWrite(1, HIGH);
}
else if(c=='2')
{
DigiKeyboard.sendKeyStroke(0);
DigiKeyboard.delay(2000);
DigiKeyboard.sendKeyStroke(KEY_H);
DigiKeyboard.delay(2000);
DigiKeyboard.sendKeyStroke(KEY_E);
DigiKeyboard.delay(2000);
DigiKeyboard.sendKeyStroke(KEY_L);
DigiKeyboard.delay(2000);
DigiKeyboard.sendKeyStroke(KEY_L);
DigiKeyboard.delay(2000);
DigiKeyboard.sendKeyStroke(KEY_O);
DigiKeyboard.delay(2000);
for(;;){ /empty/ }
}
else if(c=='0')
{
digitalWrite(0, LOW);
digitalWrite(1, LOW);
}
}
delay(500);
}`

It looks like this library and the DigisparkKeyboard both define an interrupt service routine for the same pin, See the ISR defined for PCINT0_vect from twi.cpp:821 and USB_INTR_VECTOR from usbdrvasm165.inc:39. The compiler must be translating PCINT0_vect and USB_INTR_VECTOR into the same value (__vector_2). Additionally, you can see where USB_INTR_VECTOR is defined in usbconfig.h:377, which is PCINT0_vect.

To me it looks like the libraries are incompatible with each other for this reason.

@RyanLoringCooper Do you know if there could be any solution to this issue? I've searched everywere for a solution but without any result

I found out that in the usbconfig.h it's written:

` #if defined (AVR_ATtiny45) || defined (AVR_ATtiny85)
#define USB_INTR_CFG PCMSK
#define USB_INTR_CFG_SET (1<<USB_CFG_DPLUS_BIT)
#define USB_INTR_ENABLE_BIT PCIE
#define USB_INTR_PENDING_BIT PCIF
#define USB_INTR_VECTOR SIG_PIN_CHANGE
#endif

#if defined (AVR_ATtiny87) || defined (AVR_ATtiny167)
#define USB_INTR_CFG PCMSK1
#define USB_INTR_CFG_SET (1 << USB_CFG_DPLUS_BIT)
#define USB_INTR_CFG_CLR 0
#define USB_INTR_ENABLE PCICR
#define USB_INTR_ENABLE_BIT PCIE1
#define USB_INTR_PENDING PCIFR
#define USB_INTR_PENDING_BIT PCIF1
#define USB_INTR_VECTOR PCINT1_vect
#endif`

, so it define the USB_INTR_VECTOR as SIG_PIN_CHANGE and not PCINT0_vect as you said previously but idk what does it means
