HAL Library 19- CPU LOAD monitor for STM32Fxxx

CPU load monitor library is simple library, which counts number of sleeping cycles using WFI() instruction compared to working cycles in one second. Load variable is updated every 1 second to determinate how much your processor works. For that case, you have to always put your system to sleep mode when you don’t need it. It uses DWT counter in Cortex M4/M7 to measure cycle counters! Library Read more about new HAL libraries Features Measures CPU load. Load depends between...

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...

New STM32F7-Discovery board

After STM32F411-Nucleo, STM32F439-Eval board, ST sends me a new discovery board, STM32F7-Discovery. This is a very powerful discovery board according to other series. It is also very big with a lot of features. The STM32F7 discovery kit allows users to develop and share applications with the STM32F7 Series microcontollers based on ARM® Cortex®-M7 core. The discovery kit enables a wide diversity of applications taking benefit from audio, multi-sensor support, graphics, security, video and high-speed connectivity features. The Arduino connectivity support...
