Because of the recent need to do some STM32 development, and most of my other development on Linux, often in Windows and Linux switching feeling more inconvenient, so I studied the Linux under the development of STM32 tools, by the way to do the next record.The development tools usedSoftware platform:Eclipse LunaDownload: HTTPS://ECLIPSE.ORG/DOWNLOADS/PACKAGES/RELEASE/LUNA/SR2For installing the system Workbench for STM32 plug-in, it is recommended that you download the Eclipse IDE for C + + deve

ObjectiveAs St company launched more than STM32F1 cost-effective F0 chip, now on the market F0 chip share is very high. F0 chip belongs to M0 core, the main frequency 48M (of course, can overclock, but try not to exceed too much), the resource size can be selected according to the project needs. So, in recent days, summarize the knowledge about STM32F0 development.This article mainly stm32f0, mdk-arm to explain the "new software engineering detailed process."

is 1032. Because of the user heap (Cstack) We set the 1024, so the actual application code occupies the SRAM amount of 8=1032-1024. The operational efficiency portion of the code is calculated by the number of kernel runs (Cycleconter) provided by the IAR. At the beginning and end of the function function, the breakpoint is set, and the difference between the number of two cores running cycles is the running period of the code here. The test hardware selects the nucleo-f302 evaluation board

development, viewing some of the relevant register configurations when debugging, how to use related functions, etc.Of course, the two above is about the whole chip all the information, development time also have some relevant information, such as: Application Manual, Errata Manual, Programming manual, and so on, explained some details of things, do not abandon troublesome friends, recommended reference to these documents.St Official F4 Documentation:http://www.st.com/content/st_com/zh/products

Stm32cubemx is a graphical software setup tool that allows the use of graphical wizards to generate C initialization code. It is the future development of STM32 series of mainstream software, is the initiative of St company original, can reduce development work, time and cost. Stm32cube covers the STM32 series. At present, St company recommends that software developers use the software to configure stm32 underlying code and to promote it. Welcome ever

the development of STM32: Register development, Standard peripheral library, STM32CUBEMX configuration and so on. Since there are too many registers for STM32 (unlike registers with 51 or 430), it is not recommended to use register development for beginners. The tools for STM32CUBEMX configuration code are really powerful, but not for those who want to understand the underlying driver development. Therefor

I have a piece of stm32f429 discovery Board, for some reason need to use 8080 interface lcd, and the block Development Board comes with the LCD interface using LTDC drive, so on the right atom here bought a 4.3 inch capacitive touch screen, driver IC for the NT35510.In order to quickly build a software engineering, I use the STM32CUBEMX tool to generate code templates, and write the LCD.C and nt35510.c two files, the code is as follows:Lcd.ctypedef st

This article is based on St official demo board stm32f429 Discovery Hardware platform, in order to see the figure of the form of speaking to you to explain the main parameters of LTDC configuration. The code section mentioned in this article is excerpted from my other article "stm32f429 LTDC code template", LCD hardware for 240x320, driver IC for ili9341. The purpose of this article is to let you through a few pictures can master the stm32f429 LTDC controller configuration Essentials, and from t

at the moment, I think the biggest convenience of Stm32cube is that you can use STM32CUBEMX software to graphically configure peripherals.

Fortunately, this bypass mode is not used as much as the external crystal mode, otherwise more people may be in trouble here.Let's take the 3f4 series chip as an example.As mentioned above, besides configuring hseon, the bypass mode also requires configuring hsebyp.For the standard library function voidrcc_hseconfig (uint32_t rcc_hse)Or the related parameters in the cube library function _ hal_rcc_hse_config (rcc_oscinitstruct-> hsestate) may be: rcc_hse_on, rcc_hse_bypass, or rcc
