HAL library 09- GENERAL for STM32Fxxx 3

HAL library 09- GENERAL for STM32Fxxx

With this name I mean that in this library, a lot of different stuff, maybe unrelated between, but very useful things will be implemented. It allows you to make software reset, get reset source, disable or enable global interrupts (NVIC) and more. It will be updated frequently but for now it’s just a start to use it in your projects. Library Read more about new HAL libraries Features Support for software reset with callback Get reset source, what resets your...

HAL library 08- SPI for STM32Fxxx 32

HAL library 08- SPI for STM32Fxxx

Next library in ported libs is SPI for HAL based drivers for STM32F4xx and STM32F7xx based devices. Library Read more about new HAL libraries Features Operate with up to 6 SPI peripherals Send single or multiple bytes at time Automatic SPI prescaler selection based on maximum clock selected for your external device Software based Chip Select pin Support for custom GPIO pins combination for SPI

HAL Library 07- USART for STM32Fxxx 59

HAL Library 07- USART for STM32Fxxx

Here it is. UART library for HAL based libraries. If you don’t know, how UART work on STM32Fxxx devices, then you might take a look at my first library, where I also explained how to used it. This library works successfully on F4 and F7 based devices for now. I will add support for F0 too as soon as possible. Library Read more about new HAL libraries Features Supports up to 8 UART peripherals at a time Interrupt driven RX...

HAL library 3- DELAY for STM32Fxxx 17

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 2- LEDS and BUTTON for STM32 boards 3

HAL library 2- LEDS and BUTTON for STM32 boards

Next library in series in disco library for controlling leds and reading button state on various STM32F0, STM32F4 and STM32F7 boards. Supported boards: STM32F401-Discovery STM32F4-Discovery STM32F411-Discovery STM32F429-Discovery STM32F439-EVAL, STM32F401-Nucleo STM32F411-Nucleo STM32F446-Nucleo STM32F091-Nucleo STM32F7-Discovery Library Read more about new HAL libraries Features Set LED state Read LED state Read button state Dependencies HAL TM STM32Fxxx HAL defines.h Library required settings In order to tell which board you use, you have to set some defines for it. These defines are also used in other...

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...
