Need some helpe with TFT Library

[Jimmie]

Hi i am testing the TFT library and it works fine for drawing shapes but when i add the TFT_Write_Char
and TFT_Write_Text I get a compile error saying: Too many actual parameters.
What does this mean and how do I solve it. Here is my code:

Code: Select all

  char *text = "electronics";
  char test2[2] = "7";

  
// TFT module connections
char TFT_DataPort at LATE;
char TFT_DataPort_Direction at TRISE;
sbit TFT_RST at LATC1_bit;
sbit TFT_BLED at LATD2_bit;
sbit TFT_RS at LATB15_bit;
sbit TFT_CS at LATF12_bit;
sbit TFT_RD at LATD5_bit;
sbit TFT_WR at LATD4_bit;
sbit TFT_RST_Direction at TRISC1_bit;
sbit TFT_BLED_Direction at TRISD2_bit;
sbit TFT_RS_Direction at TRISB15_bit;
sbit TFT_CS_Direction at TRISF12_bit;
sbit TFT_RD_Direction at TRISD5_bit;
sbit TFT_WR_Direction at TRISD4_bit;
// End Glcd module connections

// Touch Panel module connections
sbit DriveX_Left at LATB13_bit;
sbit DriveX_Right at LATB11_bit;
sbit DriveY_Up at LATB12_bit;
sbit DriveY_Down at LATB10_bit;
sbit DriveX_Left_Direction at TRISB13_bit;
sbit DriveX_Right_Direction at TRISB11_bit;
sbit DriveY_Up_Direction at TRISB12_bit;
sbit DriveY_Down_Direction at TRISB10_bit;
// End Touch Panel module connections

// Global variables
unsigned int Xcoord, Ycoord;
char PenDown;
void *PressedObject;
int PressedObjectType;
unsigned int caption_length, caption_height;
unsigned int display_width, display_height;

 // Example of establishing 16-bit communication between TFT display and PORTD, PORTE of MCU :






void PMPWaitBusy() {
  while(PMMODEbits.BUSY);
}

void SetIndex(unsigned short index) {
  TFT_RS = 0;
  PMDIN = index;
  PMPWaitBusy();
}

void WriteCommand( unsigned short cmd ) {
  TFT_RS = 1;
  PMDIN = cmd;
  PMPWaitBusy();
}

void WriteData(unsigned int _data) {
  TFT_RS = 1;
  PMDIN = _data;
  PMPWaitBusy();
}

static void InitializeTouchPanel() {
  AD1PCFG = 0xFFFF;
  PCFG12_bit = 0;
  PCFG13_bit = 0;
  // PMP setup
  PMMODE = 0;
  PMAEN  = 0;
  PMCON  = 0;  // WRSP: Write Strobe Polarity bit
  PMMODEbits.MODE = 2;     // Master 2
  PMMODEbits.WAITB = 0;
  PMMODEbits.WAITM = 1;
  PMMODEbits.WAITE = 0;
  PMMODEbits.MODE16 = 1;   // 16 bit mode
  PMCONbits.CSF = 0;
  PMCONbits.PTRDEN = 1;
  PMCONbits.PTWREN = 1;
  PMCONbits.PMPEN = 1;
  ADC1_Init();
    TFT_Set_Active(SetIndex,WriteCommand,WriteData);
  TFT_Init(320, 240);

  TP_TFT_Init(320, 240, 13, 12);                                  // Initialize touch panel
  TP_TFT_Set_ADC_Threshold(1000);                              // Set touch panel ADC threshold

  PenDown = 0;
  PressedObject = 0;
  PressedObjectType = -1;
}

void main() {
    TRISE = 0;
  TRISD = 0;

  //TFT_Set_Active(Set_Index,Write_Command,Write_Data);
  TFT_Init(320, 240);


  InitializeTouchPanel();

  // You can get calibration constants using touch panel calibration example
  TP_TFT_Set_Calibration_Consts(76, 907, 77, 915);    // Set calibration constants


 TFT_Fill_Screen(CL_WHITE);

  TFT_Set_Font(TFT_defaultFont, CL_BLACK, FO_HORIZONTAL);

 

  TFT_Set_Brush(0, 0, 1, LEFT_TO_RIGHT, CL_BLACK, CL_WHITE);



 TFT_Rectangle(20, 20, 219, 107);
   TFT_Circle(120, 64, 110);
    TFT_Write_Text("test", 4, 4,);  //<<<<<<<<<<<<<<<<<<<<<<<<<<<< compiler complains here
 //  TFT_Write_Char('A',22,23,);


while(1)
{
}
}

Also I wonder if anyone knows a easy way to get the name of all the files from a FAT16 SD card using the Multi Media Card Library

Hello,

you have one " , " behind second 4 (line 125), and that caused error

Code: Select all

TFT_Write_Text("test", 4, 4,);  //<<<<<<<<<<<<<<<<<<<<<<<<<<<< compiler complains here

Best regards,

This is how it appears in the help file.

Code: Select all

TFT_Write_Text("TFT LIBRARY DEMO, WELCOME !", 0, 0,);

If someone do a copy n paste, he get this error.

[Jimmie]

Thank you, yes I only mad a copy paste from the example in the library without checking properly .

I also wonder if there will be a TFT bitmap editor soon that converts pictures from jpg to hex data. Or are there any other ways to print BMP/JPG pictures using “TFT_Image_Jpeg” or “TFT_Image” function.

[Toley]

Hi Jimmie,

Visual TFT can generate the data table. You can use the demo version and only use it to covert your images.

[phil31]

Ho Toley,

do you find a way to generate the data tab to use the "TFT_image" instead "TFT_image_jpeg" procedure ?

thanks
phil

Hi phil31

do you find a way to generate the data tab to use the "TFT_image" instead "TFT_image_jpeg" procedure ?

I'm not sure I understand what you mean, but jpeg are jpeg and they need decoding. TFT_Image is used to print uncompressed images (bmp) and TFT_Image_Jpeg is used to print jpeg.

Hello,

you can use our tool Visual TFT in order to generates a code that can be used in the appropriate compiler.
