At the beginning of the main program the HAL_Init() function is called to reset all the peripherals, initialize the Flash interface and the systick. The SystemClock_Config() function is used to configure the system clock for STM32H743xx Devices : The CPU at 400MHz The HCLK for D1 Domain AXI and AHB3 peripherals , D2 Domain AHB1/AHB2 peripherals and D3 Domain AHB4 peripherals at 200MHz. The APB clock dividers for D1 Domain APB3 peripherals, D2 Domain APB1 and APB2 peripherals and D3 Domain APB4 peripherals to run at 100MHz. The BSP examples detects the presence of Adafruit 1.8" TFT shield with joystick and uSD. If the Adafruit shield is NOT connected, then: - Blue led (led2) blinks waiting the user button is pushed. - Then blue led swithces off and green & red leds start blinking at high frequency. - Pushing user button again and again blinking frequency decreases until looping to high frequency. If the Adafruit shield is connected, then this example shows how to use the different functionalities of LCD, SD card and joystick by switching between tests using user button. At the beginning of each example the blue led (led2) blinks waiting the user button to start. - Firstly, use the joystick button to move a pointer inside a rectangle (up/down/right/left) and change the pointer color(select). - Secondly, this example shows how to use the different LCD features to display string with different fonts, to display different shapes and to draw a bitmap. - Thirdly, this example shows how to erase, write and read the SD card. At the end of the three examples when pushing the user button the application loops to the beginning (first examples). @par Keywords Board Support Package, BSP, Adafruit, TFT, LCD, Joystick, SD Card @Note If the application is using the DTCM/ITCM memories (@0x20000000/ 0x0000000: not cacheable and only accessible by the Cortex M7 and the  MDMA), no need for cache maintenance when the Cortex M7 and the MDMA access these RAMs.       If the application needs to use DMA(or other masters) based access or requires more RAM, then  the user has to:               - Use a non TCM SRAM. (example : D1 AXI-SRAM @ 0x24000000)               - Add a cache maintenance mechanism to ensure the cache coherence between CPU and other masters(DMAs,DMA2D,LTDC,MDMA).         - The addresses and the size of cacheable buffers (shared between CPU and other masters) must be properly defined to be aligned to L1-CACHE line size (32 bytes).   @Note It is recommended to enable the cache and maintain its coherence, but depending on the use case       It is also possible to configure the MPU as "Write through", to guarantee the write access coherence.               In that case, the MPU must be configured as Cacheable/Bufferable/Not Shareable.               Even though the user must manage the cache coherence for read accesses.               Please refer to the AN4838 “Managing memory protection unit (MPU) in STM32 MCUs”               Please refer to the AN4839 “Level 1 cache on STM32F7 Series” @note It is highly recommanded to set the SPI parameter "MasterKeepIOState" to "SPI_MASTER_KEEP_IO_STATE_ENABLE" at init time. This configuration allows to avoid glitches on SPI lines especially the clock. Glitches that could lead to Master/Slave desynchronization. This config allows SPI Master to keep control on output state even if it is disabled. @par Directory contents - BSP/Src/main.c Main program - BSP/Src/system_stm32h7xx.c STM32H7xx system clock configuration file - BSP/Src/stm32h7xx_it.c Interrupt handlers - BSP/Src/joystick.c Joystick feature - BSP/Src/lcd.c LCD drawing features - BSP/Src/sd.c SD features - BSP/Inc/main.h Main program header file - BSP/Inc/stm32h7xx_hal_conf.h HAL configuration file - BSP/Inc/stm32h7xx_it.h Interrupt handlers header file - BSP/Inc/stlogo.h Image used for BSP example @par Hardware and Software environment - This example runs on STM32H743ZI Devices - This example has been tested with STMicroelectronics NUCLEO-H743ZI Rev.B board and can be easily tailored to any other supported device and development board. - NUCLEO-H743ZI Rev.B board Set-up - Connect the Adafruit 1.8" TFT shield (https://www.adafruit.com/products/802) - Make sure the SB146 is closed and the SB165 and SB174 are opened on the NUCLEO-H743ZI board @par How to use it ?
