# BSP STM32H7B3I-EVAL Component
![latest tag](https://img.shields.io/github/v/tag/STMicroelectronics/stm32h7b3i-eval.svg?color=brightgreen)
## Overview
**STM32Cube** is an STMicroelectronics original initiative to ease developers' life by reducing efforts, time and cost.
**STM32Cube** covers the overall STM32 products portfolio. It includes a comprehensive embedded software platform delivered for each STM32 series.
* The CMSIS modules (core and device) corresponding to the ARM(tm) core implemented in this STM32 product.
* The STM32 HAL-LL drivers, an abstraction layer offering a set of APIs ensuring maximized portability across the STM32 portfolio.
* The BSP drivers of each evaluation, demonstration or nucleo board provided for this STM32 series.
* A consistent set of middleware libraries such as RTOS, USB, FatFS, graphics, touch sensing library...
* A full set of software projects (basic examples, applications, and demonstrations) for each board provided for this STM32 series.
Two models of publication are proposed for the STM32Cube embedded software:
* The monolithic **MCU Package**: all STM32Cube software modules of one STM32 series are present (Drivers, Middleware, Projects, Utilities) in the repository (usual name **STM32Cubexx**, xx corresponding to the STM32 series).
* The **MCU component**: each STM32Cube software module being part of the STM32Cube MCU Package, is delivered as an individual repository, allowing the user to select and get only the required software functions.
## Description
This **stm32h7b3i-eval** MCU component repository is one element of the **STM32CubeH7** MCU embedded software package, providing the **STM32H7B3I-EVAL** BSP BOARD component part.
## Release note
Details about the content of this release are available in the release note [here](https://htmlpreview.github.io/?https://github.com/STMicroelectronics/stm32h7b3i-eval/blob/main/Release_Notes.html).
## Compatibility information

<h1 id="purpose">Purpose</h1>
<p>The BSP (Board Specific Package) drivers are parts of the STM32Cube package based on the HAL drivers and provide a set of high level APIs relative to the hardware components and features in the evaluation boards, discovery kits and nucleo boards coming with the STM32Cube package for a given STM32 series.</p>
<p>The BSP drivers allow a quick access to the boards’ services using high level APIs and without any specific configuration as the link with the HAL and the external components is done in intrinsic within the drivers.</p>
<p>From project settings points of view, user has only to add the necessary driver’s files in the workspace and call the needed functions from examples. However some low level configuration functions are weak and can be overridden by the applications if user wants to change some BSP drivers default behavior.</p>

* @brief This file provides a set of functions needed to manage an I2C M24LR64
* EEPROM memory.
@verbatim
To be able to use this driver, the switch EE_M24LR64 must be defined
in your toolchain compiler preprocessor
===================================================================
Notes:
- The I2C EEPROM memory (M24LR64) is available on separate daughter
board ANT7-M24LR-A, which is not provided with the STM32H7B3I_EVAL
board.
To use this driver you have to connect the ANT7-M24LR-A to CN3
connector of STM32H7B3I_EVAL board.
===================================================================
It implements a high level communication layer for read and write
from/to this memory. The needed STM32Fxxx hardware resources (I2C and
GPIO) are defined in stm32h7b3i_eval_bus.h file, and the initialization is
performed in BSP_EEPROM_Init().
You can easily tailor this driver to any other development board,
by just adapting the defines for hardware resources and
BSP_EEPROM_Init() function.
+ Call the function BSP_EEPROM_WritePage() to write a single page of 4 bytes
+ Call the function BSP_EEPROM_ReadPage() to read a single page of 4 bytes
+ Call the function BSP_EEPROM_WriteBuffer() to write a buffer of N bytes to EEPROM
+ Call the function BSP_EEPROM_ReadBuffer() to read a buffer of N bytes from EEPROM
+ Call the function BSP_EEPROM_IsDeviceReady() to verify if device is ready. This function
returns a BUSY error if the device is not ready after several trials.
@note Regarding the "Instance" parameter, needed for all functions, it is used to select
an EEPROM instance. On the STM32H7B3I_EVAL board, there's one instance. Then, this
parameter should be 0.

******************************************************************************
* @file stm32h7b3i_eval_io.c
* @author MCD Application Team
* @brief This file provides a set of functions needed to manage the IO pins
* on STM32H7B3I_EVAL board.
@verbatim
How To use this driver:
-----------------------
- This driver is used to drive the IO module of the STM32H7B3I_EVAL board.
- The MFXSTM32L152 IO expander device component driver must be included with this
driver in order to run the IO functionalities commanded by the IO expander (MFX)
device mounted on the board.
Driver description:
-------------------
+ Initialization steps:
o Initialize the IO module using the BSP_IO_Init() function. This
function includes the MSP layer hardware resources initialization and the
communication layer configuration to start the IO functionalities use.
+ IO functionalities use
o The IO pin mode is configured when calling the function BSP_IO_ConfigPin(), you
must specify the desired IO mode by choosing the "IO_ModeTypedef" parameter
predefined value.
o If an IO pin is used in interrupt mode, the function BSP_IO_ITGetStatus() is
needed to get the interrupt status. To clear the IT pending bits, you should
call the function BSP_IO_ITClear() with specifying the IO pending bit to clear.
o The IT is handled using the corresponding external interrupt IRQ handler,
the user IT callback treatment is implemented on the same external interrupt
callback.
o The IRQ_OUT pin (common for all functionalities: JOY, SD, LEDs, etc) can be
configured using the function BSP_IO_ConfigIrqOutPin()
o To get/set an IO pin combination state you can use the functions
BSP_IO_ReadPin()/BSP_IO_WritePin() or the function BSP_IO_TogglePin() to toggle the pin
state.

******************************************************************************
* @file stm32h7b3i_eval_nor.c
* @author MCD Application Team
* @brief This file includes a standard driver for the MT28EW128ABA1LPC-0SIT NOR flash memory
* device mounted on STM32H7B3I_EVAL boards.
@verbatim
How To use this driver:
-----------------------
- This driver is used to drive the MT28EW128ABA1LPC-0SIT NOR flash external memory mounted
on STM32H7B3I_EVAL board.
- This driver does not need a specific component driver for the NOR device
to be included with.
Driver description:
------------------
+ Initialization steps:
o Initialize the NOR external memory using the BSP_NOR_Init() function. This
function includes the MSP layer hardware resources initialization and the
FMC controller configuration to interface with the external NOR memory.
+ NOR flash operations
o NOR external memory can be accessed with read/write operations once it is
initialized.
Read/write operation can be performed with AHB access using the functions
BSP_NOR_ReadData()/BSP_NOR_WriteData(). The BSP_NOR_WriteData() performs write operation
of an amount of data by unit (halfword). You can also perform a program data
operation of an amount of data using the function BSP_NOR_ProgramData().
o The function BSP_NOR_Read_ID() returns the chip IDs stored in the structure
"NOR_IDTypeDef". (see the NOR IDs in the memory data sheet)
o Perform erase block operation using the function BSP_NOR_Erase_Block() and by
specifying the block address. You can perform an erase operation of the whole
chip by calling the function BSP_NOR_Erase_Chip().
o After other operations, the function BSP_NOR_ReturnToReadMode() allows the NOR
flash to return to read mode to perform read operations on it.

* @brief This file includes the SDRAM driver for the IS42S32800J-6BLI memory
* device mounted on STM32H7B3I_EVAL boards.
@verbatim
How To use this driver:
-----------------------
- This driver is used to drive the IS42S32800J-6BLI SDRAM external memory mounted
on STM32H7B3I_EVAL board.
- This driver does not need a specific component driver for the SDRAM device
to be included with.
Driver description:
------------------
+ Initialization steps:
o Initialize the SDRAM external memory using the BSP_SDRAM_Init() function. This
function includes the MSP layer hardware resources initialization and the
FMC controller configuration to interface with the external SDRAM memory.
o It contains the SDRAM initialization sequence to program the SDRAM external
device using the function BSP_SDRAM_Initialization_sequence(). Note that this
sequence is standard for all SDRAM devices, but can include some differences
from a device to another. If it is the case, the right sequence should be
implemented separately.
+ SDRAM read/write operations
o SDRAM external memory can be accessed with read/write operations once it is
initialized.
Read/write operation can be performed with AHB access using the functions
BSP_SDRAM_ReadData()/BSP_SDRAM_WriteData(), or by DMA transfer using the functions
BSP_SDRAM_ReadData_DMA()/BSP_SDRAM_WriteData_DMA().
o The AHB access is performed with 32-bit width transaction, the DMA transfer
configuration is fixed at single (no burst) word transfer (see the
SDRAM_MspInit() static function).
o User can implement his own functions for read/write access with his desired
configurations.
o If interrupt mode is used for DMA transfer, the function BSP_SDRAM_DMA_IRQHandler()
is called in IRQ handler file, to serve the generated interrupt once the DMA
transfer is complete.
o You can send a command to the SDRAM device in runtime using the function
BSP_SDRAM_Sendcmd(), and giving the desired command as parameter chosen between
the predefined commands of the "FMC_SDRAM_CommandTypeDef" structure.

* @brief This file includes the SRAM driver for the IS61WV102416BLL-10M memory
* device mounted on STM32H7B3I_EVAL boards.
@verbatim
How To use this driver:
-----------------------
- This driver is used to drive the IS61WV102416BLL-10M SRAM external memory mounted
on STM32H7B3I_EVAL board.
- This driver does not need a specific component driver for the SRAM device
to be included with.
Driver description:
------------------
+ Initialization steps:
o Initialize the SRAM external memory using the BSP_SRAM_Init() function. This
function includes the MSP layer hardware resources initialization and the
FMC controller configuration to interface with the external SRAM memory.
+ SRAM read/write operations
o SRAM external memory can be accessed with read/write operations once it is
initialized.
Read/write operation can be performed with AHB access using the functions
BSP_SRAM_ReadData()/BSP_SRAM_WriteData(), or by DMA transfer using the functions
BSP_SRAM_ReadData_DMA()/BSP_SRAM_WriteData_DMA().
o The AHB access is performed with 16-bit width transaction, the DMA transfer
configuration is fixed at single (no burst) halfword transfer
(see the SRAM_MspInit() static function).
o User can implement his own functions for read/write access with his desired
configurations.
o If interrupt mode is used for DMA transfer, the function BSP_SRAM_DMA_IRQHandler()
is called in IRQ handler file, to serve the generated interrupt once the DMA
transfer is complete.

/* File Info : -----------------------------------------------------------------
User NOTES
1. How To use this driver:
--------------------------
- This driver is used to drive the FT5336 touch screen module
mounted over TFT-LCD on the STM32H7B3I_EVAL board.
2. Driver description:
---------------------
+ Initialization steps:
o Initialize the TS module using the BSP_TS_Init() function. This
function includes the MSP layer hardware resources initialization and the
communication layer configuration to start the TS use. The LCD size properties
(x and y) are passed as parameters.
o If TS interrupt mode is desired, you must configure the TS interrupt mode
by calling the function BSP_TS_ITConfig(). The TS interrupt mode is generated
as an external interrupt whenever a touch is detected.
The interrupt mode internally uses the IO functionalities driver driven by
the IO expander, to configure the IT line.
+ Touch screen use
o The touch screen state is captured whenever the function BSP_TS_GetState() is
used. This function returns information about the last LCD touch occurred
in the TS_State_t structure.
o The IT is handled using the corresponding external interrupt IRQ handler,
the user IT callback treatment is implemented on the same external interrupt
callback.
