Summary
This function handles NMI exception.
This function handles Hard Fault exception.
This function handles Debug Monitor exception.
This function handles Memory Manage exception.
This function handles Bus Fault exception.
This function handles Usage Fault exception.
This function handles SysTick Handler.
Main program
This function handles PPP interrupt request. This function handles TIM interrupt request.
This function handles LTDC global interrupt request.
BSP_Background.
Provide the GUI with current state of the touch screen
Return Pixel format for a given layer
This routine is used by the STemWin color conversion routines to use DMA2D for color conversion. It converts the given index values to 32 bit colors. Because STemWin uses ABGR internally and 0x00 and 0xFF for opaque and fully transparent the color array needs to be converted after DMA2D has been used.
This routine is used by the STemWin color conversion routines to use DMA2D for color conversion. It converts the given 32 bit color array to index values. Because STemWin uses ABGR internally and 0x00 and 0xFF for opaque and fully transparent the given color array needs to be converted before DMA2D can be used.
Color format of DMA2D is different to STemWin color format. This routine inverts alpha that it is compatible to STemWin and vice versa
GetBufferSize
CopyBuffer
CUSTOM_FillRect
Function for mixing up 2 colors with the given intensity. If the background color is completely transparent the foreground color should be used unchanged.
The STemWin function LCD_GetpPalConvTable() normally translates the given colors into index values for the display controller. In case of index based bitmaps without transparent pixels we load the palette only to the DMA2D LUT registers to be translated (converted) during the process of drawing via DMA2D.
Static code Initialize the LCD Controller.
Initialize the LCD Controller.
CUSTOM_CopyBuffer
CUSTOM_CopyRect Copy rectangle
System Clock Configuration The system Clock is configured as follow : System Clock source = PLL (HSE) SYSCLK(Hz) = 180000000 HCLK(Hz) = 180000000 AHB Prescaler = 1 APB1 Prescaler = 4 APB2 Prescaler = 2 HSE Frequency(Hz) = 8000000 PLL_M = 8 PLL_N = 360 PLL_P = 2 PLL_Q = 7 VDD(V) = 3.3 Main regulator output voltage = Scale1 mode Flash Latency(WS) = 5
Initializes the STM32F429I-DISCO's LCD and LEDs resources.

Summary
Internal High Speed oscillator (HSI) value. This value is used by the RCC HAL module to compute the system frequency (when HSI is used as system clock source, directly or through the PLL). Value of the Internal oscillator in Hz
Adjust the value of External High Speed oscillator (HSE) used in your application. This value is used by the RCC HAL module to compute the system frequency (when HSE is used as system clock source, directly or through the PLL). Value of the External oscillator in Hz
Miscellaneous Configuration *********************** Vector Table base offset field. This value must be a multiple of 0x200.
