How to use a function in a sketch

Projects Programming

Hi,

I have some problems for writting my code, i don't know how to use those functions in my sketch:

void BPLib::gameJoyPress(byte BP_ST_BTN, byte BP_ND_BTN){
Serial1.write((byte)0xFD); //Start HID Report
Serial1.write((byte)0x6); //Length byte
Serial1.write((byte)BP_ST_BTN); //First Button byte
Serial1.write((byte)BP_ND_BTN); //Second Button byte
for(byte i = 0;i<4;i++){ //Send four zero bytes
Serial1.write((byte)0x00);
}
}
void BPLib::gameJoyMove(signed int BP_X1,signed int BP_Y1,signed int BP_X2,signed int BP_Y2){
Serial1.write((byte)0xFD); //Start HID Report
Serial1.write((byte)0x6); //Length byte
Serial1.write((byte)BP_GAMEJOY_ST_NOBTN); //First Button byte
Serial1.write((byte)BP_GAMEJOY_ND_NOBTN); //Second Button byte
Serial1.write(BP_X1 & 0xFF);	//First X coordinate
Serial1.write(BP_Y1 & 0xFF);	//First Y coordinate
Serial1.write(BP_X2 & 0xFF);	//Second X coordinate
Serial1.write(BP_Y2 & 0xFF);	//Second Y coordinate
}
void BPLib::gameJoyReleaseAll(){
gameJoyPress(BP_GAMEJOY_ST_NOBTN, BP_GAMEJOY_ND_NOBTN);
}

These are the codes i should use in the first function:

//GAMEPAD/JOYSTICK BUTTON CODES
//ST == First button combination (BTN0 to BTN7)
#define BP_GAMEJOY_ST_BTN0	(1<<0)
#define BP_GAMEJOY_ST_BTN1	(1<<1)
#define BP_GAMEJOY_ST_BTN2	(1<<2)
#define BP_GAMEJOY_ST_BTN3	(1<<3)
#define BP_GAMEJOY_ST_BTN4	(1<<4)
#define BP_GAMEJOY_ST_BTN5	(1<<5)
#define BP_GAMEJOY_ST_BTN6	(1<<6)
#define BP_GAMEJOY_ST_BTN7	(1<<7)
#define BP_GAMEJOY_ST_NOBTN	0x00

//ND = Second button combination (BTN0 to BTN7)
#define BP_GAMEJOY_ND_BTN0	(1<<0)
#define BP_GAMEJOY_ND_BTN1	(1<<1)
#define BP_GAMEJOY_ND_BTN2	(1<<2)
#define BP_GAMEJOY_ND_BTN3	(1<<3)
#define BP_GAMEJOY_ND_BTN4	(1<<4)
#define BP_GAMEJOY_ND_BTN5	(1<<5)
#define BP_GAMEJOY_ND_BTN6	(1<<6)
#define BP_GAMEJOY_ND_BTN7	(1<<7)
#define BP_GAMEJOY_ND_NOBTN	0x00

Here's a part of my sketch (with the first function):

 if (button1 == LOW){
    BPMod.gameJoyPress(BP_GAMEJOY_ST_BTN0,BP_GAMEJOY_ND_NOBTN);

    // slight delay to avoid flooding RN42.
    delay(50);

    // "lift" the key
   BPMod.gameJoyReleaseAll();

Do you think it's right way to use this function?

Thank you!!!

Please post the whole code, the snippets are not enough, sorry....

  int button4 = digitalRead(buttonPin4);
  
  
  
  // Check Button Press on Joystick
 
  if (button1 == LOW){

    // slight delay to avoid flooding RN42.
    delay(50);

    // "lift" the key
   BPMod.gameJoyReleaseAll();
    
  
  } 
  
 if (button2 == LOW){

    // slight delay to avoid flooding RN42.

    delay(50);

    // "lift" the key
    BPMod.gameJoyReleaseAll();
    
   
       
  } 


 if (button4 == LOW){
    BPMod.gameJoyPress(BP_GAMEJOY_ST_BTN7,BP_GAMEJOY_ST_NOBTN);

    // slight delay to avoid flooding RN42. 
    delay(50);

    // "lift" the key

Thank you for your help.

Hi gorafi, could you find how to use gameJoyPress and gameJoyMove functions? I'm facing the same problem
