TWR-LCD-RGB

hello,

we got a TWR-K70F120M + TWR-LCD-RGB, all the set, using Kinetis Design Studio 3.0.0 IDE.

I added LCDC_LDD componnent, configuried pins of RGB and V/H sync, added code from help "typicla use", but every time that code tried to use PutPixel(x, y, c); it throwing to ISR

PE_ISR(Cpu_ivINT_Hard_Fault)

{

/* This code can be changed using the CPU component property "Build Options / Unhandled int code" */

PE_DEBUGHALT();

}

this is the code:

void main(void)

{

/* Write your local variable definition here */

LDD_TDeviceData* dd;

LDD_LCDC_TBitmap bitmapInfo;

LDD_LCDC_TWindow windowInfo;

/*** Processor Expert internal initialization. DON'T REMOVE THIS CODE!!! ***/

PE_low_level_init();

/*** End of Processor Expert internal initialization. ***/

/* Setup drawing variables for buffer */

bitmapAddress = LCD_START_ADDRESS;

bitmapWidth = LCD_RES_X;

bitmapHeight = LCD_RES_Y;

/* Clear buffer - red color */

ClearScreen(63, 0, 0);

/* ... draw some primitives or load image data ... */

dd = LCD_Init(NULL);

/* Fill bitmap information */

bitmapInfo.Address = (LDD_TData*)bitmapAddress;

bitmapInfo.Width = bitmapWidth;

bitmapInfo.Height = bitmapHeight;

/* Fill window information */

windowInfo.X = 0;

windowInfo.Y = 0;

windowInfo.Width = bitmapWidth;

windowInfo.Height = bitmapHeight;

/* Initialize background plane 0 */

LCD_SetupBitmap(dd, LDD_LCDC_PLANE_0, &bitmapInfo);

LCD_SetupWindow(dd, LDD_LCDC_PLANE_0, &windowInfo);

LCD_SetupWindowPosOnScreen(dd, LDD_LCDC_PLANE_0, 0, 0);

/* Enable LCD */

LCD_Enable(dd);

for(;;) { }

}

what do I miss?

as I understood there are no examples for KDS.

is there any demo app that I can boot to mk70 to see something on the screen, the screen is always white, like there is no signal to it.

please help, thank you!

Hi Alon,

As you mention there are no examples for KDS using TWR-LCD-RGB but you could use the eGUI demo application for the TWR-K70F120M board fusing the TWR-LCD-RGB, you can find more information on this link:

Getting started with the eGUI (a.k.a. D4D)

Hope it helps!
