Mcu_strcuture_headerfile

This header file contains the base address peripherals like (GPIOX, SPIX,I2CX,USARTX/UARTX,TIMERSX..etc) lieing on buses(APHB1, APHB2, APHB3, APB1, APB2). And some of the peripherals structure of GPIOX, SPIX,I2CX. Even with the required macros of communicaiton protocols.

GPIO_headerfile

Contains GPIO handle structure, which can handle GPIO port (A...H) and configurations like pin(number, mode, type, speed ..etc,) and with required API prototype declaration like Initialise, De-initiaslise,read, write, and toggle..etc,.Even with the required macros of GPIOX.

SPI_headerfile

In this header file it contains SPI handle structure, which can handle SPI1, SPI2, SPI3, and SPI4 and configurations like device mode (Master or Slave mode), busconfiguration (Full duplex, Half duplex or Simple duplex), speed selection, data register (8bit or 16bit register), slave select management, CPHA, CPOL along with required API prototype declaration like Initialise, De-initiaslise,send,receive data..etc,,Even with the required macros of SPIX.

I2C_headerfile

This header file has I2C handle structure, which can handle I2C1, I2C2,I2C3, and I2C4 and configurations like device mode (Master or Slave mode), busconfiguration (Full duplex, Half duplex or Simple duplex), speed selection, data register (8bit or 16bit register), slave select management, CPHA, CPOL along with required API prototype declaration like Initialise, De-initiaslise,send,receive data..etc,.Even with the required macros of I2CX.

GPIO_library

This library contains the defintion for Intialise, Deintialise, Toggle, read and write API as menitoned in respective headerfile.

SPI_library

Spi library contians funciton definitions for the funciton declare in the header file

I2C_library

It contians defintions for the PeripheralControl, Init, DeInit, MasterSendData API's mentioned in the I2C headerfile.

Projects

The created libraries are tested with a simple project. Using SPI protocol, a communication is established between ST microcontroller and Arduino. ST controller has master, which been sending char array data "Hello World" was received at the slave arduino sucessfully.
