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...

Disable peripherals in debug mode on STM32F4xx 0

Disable peripherals in debug mode on STM32F4xx

Have you ever used watchdog in your application? Have you ever debug your application when watchdog was enabled and you hit stop? Watchdog did not stop in this case and when you pressed “continue” in your debugger, your program starts over because WDG has reset your system. One choice is that you remove line where you initialize IWDG, but you then must recompile and redownload and all that stuff. Wasting useful time. To avoid this problem, STM32 devices have possibility...

Library 62- Fast Fourier Transform (FFT) for STM32F4xx

Here is an example of Fast Fourier Transform on STM32F4xx devices. Today, I was looking something on ARM DSP documentation and I saw that some functions for FFT used in my example are deprecated and will be removed in future. 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...

Library 59- Change PLL settings while STM32F4xx is running 4

Library 59- Change PLL settings while STM32F4xx is running

I’ve been already talking about topic, how to properly set clock speed for your device with PLL settings. This article could be found here and it is definetelly worth of readiny, especially for beginners. Today, it was very rainy and bad day, so I was thinking about a library that could dynamically change PLL settings. This can be used to change current consumption of your device if there is no need for very high speed clock for some time. Changing...

Library 58- Dynamic strings on STM32F4xx 0

Library 58- Dynamic strings on STM32F4xx

Have you ever been in position where you need to store some string informations just for a small amount of time? Did you reserve ram memory before you worked with strings? If you did it like that, than this library might be a solution for you. This library was designed directly for a purpose where you need to store your information for a few time. For example, getting some string informations from your sensor, USART, etc. It uses malloc and...

FatFs library extended for SDRAM 6

FatFs library extended for SDRAM

As mentioned at the beginning of post about FATFS with SDCARD, I’ve updated library to extend support for SDRAM on STM32F429-Discovery or STM324x9-EVAL board. Low level functions have been added in library for write/read data ti SDRAM. SDRAM set up To use SDRAM with my FATFS library, you will need to include my SDRAM library, which implements low level functions for read/write in SDRAM and initialization process.  Next thing, you need to do, is to open defines.h configuration file and...
