HAL Library 16- I2C for STM32Fxxx devices

Here it is. After some email for I2C library for HAL, I’ve made it. I ported my old for F4 to HAL based libraries for F0/F4/F7 series. I added method to read single byte, multi bytes, write single byte, write multi bytes, write/read single byte from/to register which has 16-bit address size. Library Read more about new HAL libraries Features Supports up to 4 I2C peripherals Supports different pinouts selectable on initialization Supports custom pin combinations Supports multiple read/write modes...

HAL library 15- HD44780 for STM32Fxxx

HD44780 LCDs are still very popular devices in embedded project so I think you can’t without simple library for them. I’ve port my old library to HAL based libraries for these LCDs. Library Read more about new HAL libraries Features 4-bits operation mode Minimum GPIOs used (6) Supports different LCD sizes Supports up to 8 custom characters Enable/disable cursor blinking Show/hide cursor Shift content in ram left/right Connection pins to board are user selectable Automatically jumps to new line when...

HAL Library 14- Fast Fourier Transform for STM32Fxxx

Here is an example of Fast Fourier Transform on STM32F4xx devices. This HAL library works for F4 and F7 series! That was the main reason I decided to make a library for FFT on STM32F4xx. To use this library, some third-party libraries are also required. All these required files can be found in STM32F4xx Standard peripheral drivers and DSP instructions provided from ST.com from their website. Now is version 1.5.1 of these drivers and also .lib file is included for ARM...

HAL Library 13- Buttons for STM32Fxxx

New port. Buttons library for HAL based libraries. It can handle buttons, connected to your STM32Fxxx devices. It supports basically unlimited number of buttons with different triggering. Currently, callback functions can be called on these events: Button on pressed: Called directly when button is pressed Button normal press: Called when button is released after specific amount of time Button long press: Called when button is pressed for specific “long” amount of time It uses malloc() to allocate memory, so you...

HAL library 12- LCD for STM32Fxxx

LCD is first big library provided from me. It’s the same as SDRAM, it works on STM32F429-Discovery, STM32F439-EVAL and STM32F7-Discovery boards. With one library you can control 3 boards just by selecting proper define in your target. Library can be extended to other boards. Library requires FMC peripheral for SDRAM for display memory, DMA2D for fastest graphic accelerations and LTDC for transferring layers to LCD.

HAL library 11- SDRAM for STM32Fxxx

SDRAM library was designed to be used on STM32F429-Discovery, STM32F439-EVAL and STM32F7-Discovery boards. With single define, library will know which board is used and which settings should use to get proper working for RAM. FMC peripheral is used for driving SDRAM. Library Read more about new HAL libraries Features Use SDRAM on STM32F429-Discovery board Use SDRAM on STM32F439-EVAL board Use SDRAM on STM32F7-Discovery board Supports custom pins initialization in case user has own board with RAM Supports commands for read...
