STM32F4xx_customLibrary

At the moment it is not a complete library like HAL or SPL. The purpose of this library is to understand in detail how to work with the controller's peripherals. As needed, I add new drivers and features.

Library content

• MISC driver
• RCC driver
• GPIO driver
• DMA driver
• SPI driver
• UART driver
• I2C driver
• CAN driver

How to use

• сonnect ush_stm32f4xx_conf.h file to your project;
• comment out/uncomment required drivers in ush_stm32f4xx_conf.h file.

Further possible improvements

Since the drivers are obviously raw, then all the improvements can be listed indefinitely, however, I would like to note the following general changes:

• redesign of SPI and UART drivers, since at the time of their design it seemed to me a great idea to add initialization of auxiliary peripherals such as GPIO and DMA inside. Because of this, the initialization functions turned out to be unnecessarily complex and long;
• bringing all drivers to a single code style such as in I2C and DMA drivers, as well as getting rid of unnecessary enumerations;
• add error handling
