[ugfx LTDC and chibios]

I update repository and now works good. thank you.

[ugfx LTDC and chibios]

Hi

Is there any example use ltdc with https://github.com/ChibiOS/ChibiOS-Contrib.

I test ugfx with STM32F429i-Discovery board on chibios 3 but not work.

[Support RTL language For ugfx]

I worked to integrated fribidi to show Bidirectional (Complex RTL and LTR) language in ugfx.

This is my repository

https://bitbucket.org/vahid_sohrabloo/ugfx

I Tested on stm32f429 with ili9341 and correct work.

I create fribidi folder in 3rdparty and create one example (fonts_bidi)

Please check my code if no problem I create pull request.

[ugfx custom font error]

you right.

I am php programmer . if I can help please tell me

[ugfx custom font error]

Hi

I want to use custom font but any ttf file uploaded to ugfx.org/fontconvert.php say "Could not import font - bad file format?"

[µGFX and mbedos]

I worked on touch and widgets.

[µGFX and mbedos]

Finally Work. Horaaaaaaaaaaa.

Very thank you inmarket .

I very soon release my code and work on touch.

But I change very litle in ugfx.

[µGFX and mbedos]

are you sure you're code is correct?

I have error

./ugfx/src/gos/gos_mbed.h:52:9: error: 'gfxMutex' does not name a type
typedef gfxMutex void;

[µGFX and mbedos]

sorry for my bad English. I have question. I Switch to Mbed 2. and try to display.

I need to use mbed data type in H file (Muttex) In example.

I don't know how to handle. I can't Use mbed.h in header but need datatype Mutex that defined in mbed.h.

Just please help in Mutex functions.

[µGFX and mbedos]

Thank you.

I need to use some type in mbed.h (need c++) to define in gos_xyz.h file

like this

in my header file need Mutex object type

void gfxMutexInit(Mutex *pmutex);

and in my cpp file

void gfxMutexInit(Mutex *pmutex)
{
  //todo
  *pmutex = new Mutex;

}

[support unicode and RTL language]

did ugfx support unicode and RTL language such as Persian, arabic and ....

[µGFX and mbedos]

Thank you.

I finaly compile with out error and runtime error. but on my dispay not show anything.

I create new ili9341 to work with mbed spi

void init_board(GDisplay *g){

    _spi.format(8,0);                  
    _spi.frequency(100000);

     _CS=1;
     _DC=1;
     _reset=1;


}



void post_init_board(GDisplay *g) {

  (void) g;


}


void setpin_reset(GDisplay *g, bool_t state) {
  if (state == TRUE) {
    _reset=0;

  } else {
    _reset=1;
  }
  (void) g;

  // (void) state;
}

void setpin_dc(GDisplay *g, bool_t state) {
  if (state == TRUE) {
    _DC.write(1);

  } else {
    _DC.write(0);
  }
  (void) g;
  // (void) state;
}

void set_backlight(GDisplay *g, uint8_t percent) {
  (void) g;
  (void) percent;
}

void acquire_bus(GDisplay *g) {
  _CS = 0;
}

void release_bus(GDisplay *g) {
  _CS = 1;
}

void write_index(GDisplay *g, uint16_t index) {

  _DC.write(0); // 0=cmd
  _spi.write((int)index);      // write 8bit
  _DC.write(1); // 1=data next
}

void write_data(GDisplay *g, uint16_t data) {
  _spi.write((int)index);      // write 8bit
}

void setreadmode(GDisplay *g) {
  (void) g;
}

void setwritemode(GDisplay *g) {
  (void) g;
}

int16_t read_data(GDisplay *g) {
  return _spi.write(0);
}

and in my app

coord_t   width, height;
  coord_t   i, j;
    gfxInit();

    width = gdispGetWidth();
    height = gdispGetHeight();

    // Code Here
  gdispDrawBox(10, 10, width/2, height/2, Yellow);

[µGFX and mbedos]

I remove mbed.h and compile with gcc and not give me error.

[µGFX and mbedos]

I very try to fix this but I dont know how to fix.

I include drivers/gdisp/ILI9341/gdisp_lld_ILI9341.c file but I have this error again

/home/vahid/blinky2/yotta_modules/mbed-ugfx/source/src/gdisp/gdisp.c:607: undefined reference to `GDISPVMT_OnlyOne'

[µGFX and mbedos]

My g++ version

gcc version 4.9.3 20150529 (release) [ARM/embedded-4_9-branch revision 224288] (GNU Tools for ARM Embedded Processors) 

Ok I change some code in ugfx to work correctly with g++

but now I have again problem

[µGFX and mbedos]

I can't use gcc beacuse I need to include mbed/mbed.h and mbed use c++ library. I must use g++

[µGFX and mbedos]

I have one problem

mbed program language is C++

ugfx program language is C

I need to compile with g++ and ugfx have many problem to compile with g++.

do you have any solution?

[µGFX and mbedos]

mbedOs provice allocator manager. is this memory manager?

https://github.com/ARMmbed/ualloc

I very amatur on embeded device. but try to integrate with MbedOs and sure publish as open source.

[µGFX and mbedos]

Thanks for response.

I found that ugfx need thread. but mbedOs dos't have thread and just use minar

https://github.com/ARMmbed/minar

Is possible to use ugfx with minar?

[µGFX and mbedos]

MbedOs 3 released.

can I use µGFX with MbedOs?
