HAL library 3- DELAY for STM32Fxxx 16

HAL library 3- DELAY for STM32Fxxx

Delay functions are needed in your program, no matter how optimized and fast program you wanna do. Delay functions I’ve updated my delay library to support milliseconds and microseconds delays. Milliseconds based delay is done using systick timer which makes interrupts every 1ms generated by HAL library. For microseconds based delay, DWT cycle counter is used to get maximal optimized delay. DWT unit is for F4 and F7 only, F0 series does not have DWT, because of Cortex-M0. Software timers...

HAL library 1.5- GPIO for STM32Fxxx 6

HAL library 1.5- GPIO for STM32Fxxx

GPIO library is second mainly used library in your project. It is designed to be very easily used for initializing GPIO pins without making sure if clock is enabled or not because this will library do for you. It can init pin as normal or alternate with passing alternate function, it can deinit pin to set it as analog input, it can read pin, set pin and more. Library Read more about new HAL libraries Features Initialize pins with single...

HAL library 01- RCC for STM32Fxxx 8

HAL library 01- RCC for STM32Fxxx

This is first description for libraries in HAL section for STM32F4 and F7 lines using HAL drivers provided from ST for each section. RCC (Reset and Clock Control) library is needed to set up clocks for running STM devices at high speed. It sets up PLL parameters provided from user and enables internal or external high speed clock. Library Read more about new HAL libraries Features Works on STM32F0xx, STM32F4xx and STM32F7xx series Enables HSE or HSI oscillator Sets PLL...

All STM32 HAL libraries 106

All STM32 HAL libraries

In this section, I will write all libraries based on HAL drivers from ST. If you see this first time, make sure you read this post first about how structure of my libs looks like!

New library system built on STM32Fxxx HAL drivers 123

New library system built on STM32Fxxx HAL drivers

As you maybe saw, when STM32F7-Discovery board arrived, I switched to make libraries also for this board. And if you want easy libs for this boards, you have to switch to HAL drivers provided from STMicroelectronics. HAL drivers are basically supported for all STM32 families, so I decided to make a library in a way, that will be very easily to used with any STM32 family, especially targeted to these 3 series: STM32F0xx: For very basic and small project can...
